Tyrutils-ericw V0.15.1
Hey, I got around to setting up a website for my branch of tyrutils: (complete with lots of screenshots of different settings of AO, sunlight, etc!)
http://ericwa.github.io/tyrutils-ericw
and making an "official" release of it.

Nothing major changed compared with the last snapshot (may 1st), but a couple new things:

* .lux file support from Spike, for deluxemapping
* gamma control with -gamma flag and "_gamma" key
* rename -dirty flag to -dirt for consistency
* fence texture tracing is now opt-in only with the "-fence" flag.
* light should run a bit faster

This doesn't have lit2. Not sure what to do with that, tbh.

If there's a demand for it, I was thinking I could make a tool that upscales all textures in a wad by 2x or 4x, and adds a "-2x"/"-4x" suffix to the names. You could then manually get the higher-res lightmap on certain faces by applying the upscaled texture, and lowering the texture scale to 0.5 or 0.25 in your editor.

The only real disadvantage of this hacky method over lit2 is more face subdivision by qbsp. This isn't great, but it shouldn't be an issue if the hack is used sparingly (and bsp2 can be used if needed for higher face/vert limits.)

Anyway, enjoy, I hope this is pretty bug-free.
 Nice Site!  #1 posted by generic on 2015/07/15 13:51:22 I like being able to preview the different light settings with just a click of a button :)    #2 posted by Spirit on 2015/07/15 19:25:07 worst quake site ever, what is this, 2115?  Under Construction.gif  #3 posted by mfx on 2015/07/15 20:07:18 give him some time, you.. Nice site eric, i actually learned some new things i wouldnt have with playing around with it.    #4 posted by JneeraZ on 2015/07/15 20:11:15 I like it. Modern day Quake lighting is insane. It would be totally possible to make a great looking monochromatic level these days. Fuck textures. :)    #5 posted by jakub on 2015/07/15 21:12:38 nice page ericw. those comparison pictures are really informative. i'm not a mapper, but i'm seriously considering relighting some of the levels in my collection just to see how it would look like. - warrenm is right monochromatic levels would be great. i've just recently finished naissancee and i was impressed. i would love to see something like that in quake. imagine it... black/white level and the only color would be red bloodstains. - jakub    #6 posted by JneeraZ on 2015/07/15 21:14:16 I should redo White Room ... heh.  This All Looks Very Pretty.  #7 posted by Breezeep_ on 2015/07/16 04:49:59 I would like to make a map with all this, but at the same time, I'm too lazy to even make one properly.  Fgd File For Ericw Tools  #8 posted by DaZ on 2015/07/21 20:57:21 (Consider this a beta as only I have tested it, but it seems 100% bug free!) I have created a .fgd file with all the new parameters for Ericw's compiler suite built in and some nice quality of life upgrades (rgb color pickers etc) for you all. https://dl.dropboxusercontent.com/u/33279452/quake4ericwTools.fgd Let me know if you do find any bugs or confusing titles etc. USE THE HELP BUTTON AS ALL THE DETAILED EXPLANATIONS OF EVERY NEW COMMAND ARE IN THERE <3 <3 <3    #9 posted by JneeraZ on 2015/07/22 12:14:49 New Jackhammer, new compile tools, new FDG ... truly, this will be the jam of kings! Thanks DaZ!    #10 posted by JneeraZ on 2015/07/22 12:16:26 One quick thing in this new FGD ... monsters don't have directional arrows on them anymore. Also, lights used to be colored sprites in Jackhammer. Now they're boxes.  Eh  #11 posted by DaZ on 2015/07/22 14:44:52 The monsters thing is really weird, I didn't touch any of that part at all! As for the lights being boxes, I am sure there is a bit of code to tell the editor what sprite to use for entities but I don't know what it is :| I will investigate!  Oh  #12 posted by DaZ on 2015/07/22 14:48:00 by directional arrows you mean in the 3d view? I thought you meant the direction spinner in the entity properties :P Ok, I'll see where this stuff is so I can add it.  BETA 2 :)  #13 posted by DaZ on 2015/07/22 15:19:28 * added editor models for all items that have a model * added direction arrows to everything has a direction (direction arrows do not show when a 3d model is rendered in place of a solid box) * Lights now have proper sprites and/or 3d models. * entities now appear in the correct position when clicked into the 3d view (mostly) https://dl.dropboxusercontent.com/u/33279452/quake4ericwTools.fgd  Nice  #14 posted by mfx on 2015/07/22 15:30:16 and thx! I think func_detail doesnt need the shadowself and shadow keys.  Hmm  #15 posted by DaZ on 2015/07/22 15:48:24 I'm not sure how to remove just those two entries from a single func_* entity def. The new solid entity parameters are all inside the base solid entity class.  There More  #16 posted by mfx on 2015/07/22 15:56:28 the minlight also doesnt work on them. The whole ModelLight thing can be left out.    #17 posted by JneeraZ on 2015/07/22 15:59:55 Haha, awesome! I think this marks the first time that I've EVER had actual models show up in Jackhammer. This is now the greatest FGD of all time. OF ALL TIME!  BETA 3 :)  #18 posted by DaZ on 2015/07/22 16:53:21 * Additional options removed from func_detail as they don't work * Re-added func_illusionary as somehow I deleted it :P https://dl.dropboxusercontent.com/u/33279452/quake4ericwTools.fgd Ok, I think it's there! Let me know if you find anything else.    #19 posted by - on 2015/07/22 19:18:40 ]@PointClass = info_notnull : "info_notnull (spotlight target)" This line is incorrect, the correct usage for info_notnull is for "teh hax".  BETA 4 :D  #20 posted by DaZ on 2015/07/22 21:56:09 * Spotlight angle renamed to Spotlight direction * Spotlight angle (sets spotlight cone in degrees) https://dl.dropboxusercontent.com/u/33279452/quake4ericwTools.fgd Sorry I had no idea I sucked so bad at this :P Hopefully this will be final version!    #21 posted by JneeraZ on 2015/07/22 22:38:58 Nah, you're a hero for making this thing. It'll make Jackhammer a lot more fun to use during this jam. You've got my vote, congressmen.    #22 posted by Breezeep_ on 2015/07/23 23:58:41 Does the -lightmapscale command only work in the dev builds?  Yeah  #23 posted by ericw on 2015/07/24 00:12:14 that got cut, I guess. See the comment about lit2 in the top post.  BETA 5 :)  #24 posted by DaZ on 2015/07/25 03:11:21 * Removed setting a default for Deviance as it actually forces the light to use deviance! https://dl.dropboxusercontent.com/u/33279452/quake4ericwTools.fgd This can bring your light compile to a slow crawl so be sure to update if you are using this fgd!  Texture Surface Lighting Is A Pain In The Ass To Work With.  #25 posted by Breezeep_ on 2015/07/25 04:29:42 Any advice on how to prevent it from creating too much light and containing it at a small fade scale?  Yeah  #26 posted by ericw on 2015/07/25 05:00:40 I need to put some examples on the website for doing lava surfaces. Here's one that uses two surface lights on the lava: http://i.imgur.com/FAmAZlM.png delay 2, light 20 for the fill light delay 0, light 200 for the direct glow If you use "delay 2" make sure to use low light values or you'll end up with a fullbright room.  Pew Pew  #27 posted by DaZ on 2015/07/25 05:05:16 If you are using my fgd file, download the latest version of it as it causes a bug where all point lights will be deviance lights (each light is broken up into 16 lights!) Make sure to remove any _samples key/values from any lights you have in your level, as they will be left over even after downloading the bug fixed fgd file. If you haven't been using that fgd file, then can suggest some settings for your surface light for lava : wait 3 delay 2 light 100 you can tweak "wait" to have the light be smaller/larger but I've found these settings to be quite nice.  Mind Blown  #28 posted by DaZ on 2015/07/25 05:07:04 Never actually considered that you can use two lights on the same surface :O  Other Stuff  #29 posted by ericw on 2015/07/25 05:16:06 How the surface lighting works exactly: if you look at the BSP surfaces in-engine with "r_drawflat 1", each surface with a matching texture will get a light copied in the centre of the surface, 2 units above it. However, if a surface is larger than 128x128, it's subdivided into sections no larger than 128x128, and the lights are placed above those sections. So, you can think of the lights as being tiled roughly on a 128x128 grid. My lava screenshot above is ugly, so if anyone comes up with a good example scene for lava settings that you want to put on the tool website, that would be welcome!  Personally  #30 posted by - on 2015/07/25 05:28:50 What I've found works best for lava: use really low surface lights just to fill areas (if you find it necessary), and then hand place a couple really bright lights that will do the heavy lifting and cast your major shadows in the area. and be sure to set "_dirt" "-1" on the lava lights, you don't want dirty corners next to your lava!    #31 posted by JneeraZ on 2015/07/25 11:23:51 "Never actually considered that you can use two lights on the same surface :O " !! Same. No idea ... neat!  Oh Shit  #32 posted by DaZ on 2015/07/25 17:09:57 You could use a 2nd light with a high offset on the lava and make it a bounce fill light. AWWWWW YYYYEAAAAHHHH    #33 posted by ma†echa on 2015/07/28 09:38:01 hey DaZ, when I try to load your .fgd (Beta 5) in TrenchBroom I get the following error: "Parse error at line 26, column 39: Expected token type closing bracket, or word but got colon" Personally I'm guessing it's TB's parser, not your .fgd  Hmm  #34 posted by DaZ on 2015/07/28 18:22:42 Looking at the row/col. It's the first line of added code in the file, so I'm guessing that the version of fgd the file is written in is incompatible with TB. This fgd was written for Jackhammer / Valve Hammer and probably uses some things that are not compatible with Trenchbroom (the colour picker comes instantly to mind). It's worth noting that you can still use all these new features that are exposed in this fgd, you just have to add the key/value pairs manually.  It's A Bug  #35 posted by SleepwalkR on 2015/07/28 18:59:44 TB doesn't like the comments after the second colon. This is an oversight by me, I didn't read the FGD spec carefully enough, and the FGD files I had used for TB didn't contain such comments. File a bug report and attach the file so that it gets fixed, please.    #36 posted by JneeraZ on 2015/07/28 19:31:21 So I guess a temp fix would be to just delete the comments. In case that wasn't obvious. :)  But  #37 posted by DaZ on 2015/07/28 19:57:40 the comments are useful as they show up in jackhammer/hammer help screen. That's why I added them in the first place :D But yes, you could remove all the comments and it should work.    #38 posted by JneeraZ on 2015/07/28 20:19:12 Right, I get that. But it's either wait for someone to fix Trenchbroom OR start using the FGD now. So ... choose your path, fair user. :)    #39 posted by ericw on 2015/07/28 20:22:49 The fgd won't be useful in tb1 anyway, since tb1 doesn't display the key/values part of the fgd. Will be nice in tb2 though :-)  Func_group  #40 posted by necros on 2015/07/30 05:34:23 do func_groups get ignored or something? I have a map with a func_group in it with ~4k brushes in it, but qbsp finishes in 1 second with the following: ---- LoadMapFile ---- *** WARNING 06: No info_player_deathmatch entities in level 19190 faces 4766 brushes 4 entities 2 unique texnames 38380 texinfo Opened WAD: ..\..\QE3\gfx\jam6\mapjam666.wad Opened WAD: ..\..\QE3\gfx\jam6\lavacity1a.wad Opened WAD: ..\..\QE3\gfx\sock_palc_supp.wad Processing hull 0...

There's a bug that happens if there are no regular brushes.    #42 posted by necros on 2015/07/30 05:54:42 haha yup! thanks! and while you're here... currently in this qbsp, mixed face contents is a full error that halts compilation, while other compilers (aguirre's in my case) will just give you a warning and convert the brush to a solid. any chance of doing the same here? mixed face contents really isn't a big deal, at least, not enough to warrant an error.  Nice :)  #43 posted by ericw on 2015/07/30 05:59:47 re: mixed face contents, sure, I'll look into how bjptools handles it    #44 posted by JneeraZ on 2015/08/02 12:44:02 One quick suggestion ... when the user doesn't specify "-threads" maybe set the value to "# of cores in this machine" - 1. That leaves one core available for working on the level or checking email or whatever. I found when I set up my batch file to use one fewer core than I actually have, working on maps became a lot more fluid...  Daz  #45 posted by SleepwalkR on 2015/08/02 20:40:57 Your fgd file contains a few integer properties with float default values such as in line 34: _range(integer) : "Global light range" : 0.5 : "Scales the brightness range of all lights without affecting their fade discance. Values of n more than 0.5 makes lights brighter and n less than 0.5 makes lights less bright. The same effect can be achieved on individual lights by adjusting both the 'light' and 'wait' attributes" That's technically invalid and I don't know what JackHammer and others would make of it. TB currently crashes at that line. I'll fix it and round such values.  And More  #46 posted by SleepwalkR on 2015/08/02 20:46:05 In line 76, there is this: @baseclass base(Appearflags) flags(Angle) size(-16 -16 -24, 16 16 32) offset(0 0 24) color(0 255 0) = PlayerClass [] The flags(Angle) part is syntactically wrong. Check https://developer.valvesoftware.com/wiki/FGD  Re: #44  #47 posted by necros on 2015/08/02 22:33:44 While doing n-1 threads by default works, I think I'd prefer auto-setting priority to "below-normal". This way, when the computer is idling, it'll use all cores, but if needed, it can be put into the background while you work on your map.    #48 posted by JneeraZ on 2015/08/02 22:35:02 That might work too. All I know is that right now, if I don't hand set the thread count, I end up with a machine that can't do much while light runs...    #49 posted by necros on 2015/08/02 22:59:46 haha yeah, i know what you mean. as a workaround, you can start light/vis with the start.exe command: START /BELOWNORMAL light.exe to manually set thread priority.  Nice  #50 posted by ericw on 2015/08/02 23:05:19 I'll make it do that automatically in the next release  I Have An Iq Of -94  #51 posted by DaZ on 2015/08/03 16:09:00 Sleepwalkr, I'm fixing the fgd but I don't understand a few parts of it. _range(integer) : "Global light range" : 0.5 : "Scales the brightness range of all lights without affecting their fade discance. Values of n more than 0.5 makes lights brighter and n less than 0.5 makes lights less bright. The same effect can be achieved on individual lights by adjusting both the 'light' and 'wait' attributes" If I just set the value type to float instead of integer will that fix the error? This value defaults to 0.5 and 1 will change light values in the map. @baseclass base(Appearflags) flags(Angle) size(-16 -16 -24, 16 16 32) offset(0 0 24) color(0 255 0) = PlayerClass [] Honestly I just copied this from the fgd that ships with Jackhammer so I don't actually understand it. Can you post the correct syntax and I can update it! <3 <3    #52 posted by necros on 2015/08/03 16:20:12 For float values, just use string!  Daz  #53 posted by SleepwalkR on 2015/08/03 19:49:58 The integer vs. float thing: Integers cannot (or at least should not) have non-integer values, so that default value of 0.5 is nonsensical. Either use float or use an integer default value. If non-integer values are supposed to be okay, then do this: _range(float) : "Global light range" : "0.5" : "yadda yadda" As necros said, default values for floats should be in quotes. As for the flags thing, what are these flags actually for? Does that specify additional spawnflags? Maybe it's something only JH understands. Either way, TB2 now ignores such things (and gives a warning), but it would be cool if that FGD were compatible with all editors. If you want, I'll make you a TB2 build to test with so that you can make all warnings go away.    #54 posted by onetruepurple on 2015/08/03 19:52:05 TB1 also doesn't like the "color255" types used by JH.  Ok  #55 posted by DaZ on 2015/08/03 20:01:13 It might be JH specific. Thinking about it now it might be the part that tells the editor to show the direction arrow in the 3d view for info_* and monster_* entities. I will change to a float for those two non integer integers. Onetruepurple : the color255 brings up the colour wheel for selecting light colours in an rgb 255 format. it's too useful to remove. It would be wonderful if TB supported something like this but for now I guess sleepwalkr can ignore this specific attribute?    #56 posted by onetruepurple on 2015/08/03 20:05:33 TB has a full fledged color picker but I wasn't sure how to replace color255 with it.  It Does?  #57 posted by DaZ on 2015/08/03 20:12:16 I can't find it. TB or TB2?  Derp?  #58 posted by onetruepurple on 2015/08/03 20:20:30   #59 posted by ericw on 2015/08/03 20:21:35 I'm not sure how it's set up internally, but if you add a "_color" key to a light in TB1, a color editor shows up when that row is selected.    #60 posted by necros on 2015/08/03 20:54:19 i think it is hardcoded currently? _sunlight_color gives a picker, but _sunlight2_color does not, for example.  TB1 Doesn't Support It  #61 posted by SleepwalkR on 2015/08/03 21:06:23 TB2 will at some point. Right now, the special semantics of that property are ignored, but it will load and it will show up in the editor.  The Color Picker  #62 posted by SleepwalkR on 2015/08/03 21:07:34 it's not hardcoded, but it tries to guess whether a property is a color property by examining it's name. It's flaky, and the color255 and color1 property definitions in the FGD would surely help. I will support those in TB 2.1    #63 posted by Rick on 2015/08/04 00:14:17 I just tried out this new light utility. I'm have trouble getting lava to look right, but I'm sure I'll get it figured out. One question. Is there a limit to how many surface lights? Because I'm getting some ideas here. I realize it's just one light per texture name, but if I have 30 different light type textures, each can have a different type of surface light emit?  Actually,  #64 posted by ericw on 2015/08/04 00:20:54 no problem having multiple surface lights with the same texture name. The way to think of it is the "_surface" key causes a light to be deleted, and then copies placed across surfaces with that texture. There is currently a 65k limit on total number of lights, for no good reason, but the light tool will be really slow if you get anywhere near that number of lights.    #65 posted by Rick on 2015/08/04 00:56:05 Okay, so it's possible to have multiple different style lights per texture name in addition to many light emitting textures. This is pretty cool. Just as an experiment I lit up a rock formation inside a cave with a func_wall then removed the brush using killtarget on a trigger when the map loaded. Worked fine. I like that the color of the light is controllable. The Quake 2 surface light color was taken from the texture which probably contributed to its reputation for garishly colored lighting.  Surface Lights Moved From Jam Thread...  #66 posted by necros on 2015/08/04 23:46:56 yeah, what happens is the surface lights are already spawning arrays of lights, then each of those lights gets another array of lights. I ran into the same thing, but when you think about it, deviance on surface lights is only necessary if it is a single light (eg: a small wall texture), but not in the case of lava. i wonder if you could track how many lights have been spawned as part of the surface lighting and if it is over a threshold, do not apply deviance lighting. just some internal tracking, nothing added to the actual map or anything. because you would want to use deviance lights for small 32x32 lights, for example.  Hm Good Idea  #67 posted by ericw on 2015/08/05 00:08:43 That would be nice to have. Maybe I was premature to disable combining _deviance + _surface; I could just make it print a warning.  Jitterning  #68 posted by Rick on 2015/08/07 21:56:38 ericw, I had to switch to a faster computer for building the bsp because light was getting pretty slow on my editing computer. I now get those jitterning messages I asked about in the mapping thread. First time I've seen them. Not just a few, but screen after screen of it, but it doesn't take very long to get to the progress indication and the resulting bsp is fine, I just thought you might like to know.  Can You Check You're On The Latest Version?  #69 posted by ericw on 2015/08/07 23:12:37 Duh  #70 posted by Rick on 2015/08/08 01:33:43 Stupid me. There's a copy of the 7/13/2015 zip sitting right there in the maps folder. I guess I downloaded the newer version but forgot to extract it, because the exe in that folder (the one I'm using) is dated 5/15/2015.  Windows Symlinks  #71 posted by necros on 2015/08/09 06:19:40 is there a problem with reading .wads from symlinks? I can only use a single .wad file, if i try to add more than one, it will only read one of them. although... maybe it's not related to symlinks as it happens if it is absolute or relative paths.  Help Installing Tyrutils-ericw On Linux  #72 posted by former_total_newbie on 2015/08/09 17:33:02 So I've downloaded and extracted the tgz archive, but I don't know where to go from here (can't remember how I got the original tyrutils up and running, and I'm sure I didn't do it in the most elegant way). Also, I'm not sure if downloading the archive was the best first step, as I'd ideally like to set it up so as to be directly update-able from github (the way I've got TB2 set up -- but I needed a hell of a lot of help in getting that up and running too, and understood virtually nothing of what I was doing!). Could someone give me some noob-friendly instructions, or tell me where I can find them?  Sure  #73 posted by ericw on 2015/08/09 18:22:51 I should add these to the readme. Assuming you start in your home directory, git clone https://github.com/ericwa/tyrutils-ericw.git cd tyrutils-ericw make If there are no errors this will generate ~/tyrutils-ericw/bin/qbsp, etc. To update: cd tyrutils-ericw git pull make clean make  Thank You So Much!  #74 posted by former_total_newbie on 2015/08/09 18:43:57 That was painless :) Am I correct that the actual programmes are now in tyrutils-ericw/bin? Do I need to cd into that directory every time I wish to compile, light, etc.? Also, do I need to have the files I want to use (e.g. the .map file from which I want to create a .bsp) inside the tyrutils-ericw/bin directory? I ask because that was the only way I could ever get the original tyrutils to work, but I suspect there might be another way...    #75 posted by ericw on 2015/08/09 19:17:17 the actual programmes are now in tyrutils-ericw/bin Yup. You can run the from another directory by using the full path to the tool, like this, if you had maps in ~/maps: cd maps ~/tyrutils-ericw/bin/qbsp test.map -- What I actually do is use this build script: https://gist.github.com/ericwa/360f35c92a0139961f35 If you want to try that, save it as build.sh, update the UTILSPATH and DEST variables to match your tyrutils bin path and quake/id1/maps path, run chmod +x build.sh to make it executable, and copy it to your mapping directory. Now you can do: ./build.sh test.map and it will compile and copy the resulting bsp/lit to your quake/id1/maps folder.    #76 posted by ericw on 2015/08/09 19:17:18 the actual programmes are now in tyrutils-ericw/bin Yup.

I'll give that a shot. Spirit, no, I'm on Mint -- but thank you for offering.  Beta For Next Release  #79 posted by ericw on 2015/08/10 18:10:42 download Changes since 0.15.1: * qbsp: make "mixed face contents" and "degenerate edge" non-fatal, from txqbsp-xt * qbsp: make "-oldaxis" the default. new "-nooldaxis" flag to get the previous behaviour. * light: add "-surflight_subdivide" flag to control amount of surface lights created * light, vis: use below normal process priority on Windows * light: allow negative surface light offset * light: ensure light values in the bsp equal the average of the lit file color components. This fixes "dark" colors (where all components are < 1), on some engines (such as MarkV), which require the bsp lightmap brightness to match the .lit brightness as a cheat prevention mechanism. * light: fix lighting of hipnotic rotating entities. * light: fix crash in "Bad texture axes on face:" Thanks to everyone for testing & reporting bugs :D  Thank You!  #80 posted by mfx on 2015/08/10 18:47:23     #81 posted by Rick on 2015/08/10 21:15:17 I've run my lava map through this new lighting program about 20 times this morning and I'd have to say that the sub_divide switch has definitely helped. There is one room with a large rectangular area of lave (320x2048) which does not get lit (well, it does but very dim). In game, r_drawflat shows this lave as one single color. I think adding some structure to break the lava surface up more will fix the problem. I still have problems getting enough light near the lava without having it light up the entire cave, but I've got it pretty close. I'm up to wait 18 and my puny little 200 value delay 5 lava surface light still lights the the ceiling 1200 units above, but not a lot.  Negative Offset  #82 posted by Rick on 2015/08/10 22:49:28 The negative offset is very useful. You can sink the lava lights down below the surface and eliminate much of the spotty appearance, doesn't help much with default delay lights though. Those just basically paint the walls/shores up to a point then stop, which looks pretty bad, I've decided default delay is mostly useless for lava lights.    #83 posted by ItEndsWithTens on 2015/08/12 03:17:26 I'm working on a map for Jam 6, like so many others, and in experimenting with surface lighting using the beta Tyrutils posted earlier, I've run into a problem. As far as I can tell, 'samples' on a light entity is being used whether 'deviance' is set or not. Even in a simple box test map, making one light and setting its texture name to the floor texture, with the deviance key either unset or set to 0, I get a certain number of total lights reported. Lowering the samples value down from its default 16 to 1 reduces the total count. With the total light count being a new addition, I can't confirm whether this is new behavior or not. I've had one other problem, where light exits with no errors after reporting "X entities, Y are lights" but before actually computing any lightmaps, but I'm still trying to find a minimal repro for that one. The deviance/samples thing is either more pressing, or just me being an idiot, so I thought I should speak up now. Am I just misunderstanding how to use these features?  Martin  #84 posted by DaZ on 2015/08/12 05:20:48 If you are using that fgd I created for JH I strongly suggest getting the latest version at https://dl.dropboxusercontent.com/u/33279452/quake4ericwTools.fgd as an old version set _samples 16 (which is default, but doesn't need to be set by the fgd) which caused some lights to use deviance automatically. With the new fgd this doesn't happen (but you will still need to remove the _samples key from any lights that had it assigned before you got the new fgd). And err, if you aren't using that fgd, then ignore all of this post. YAY!  Aha  #85 posted by ItEndsWithTens on 2015/08/12 06:11:32 Yes, I was indeed using an outdated version of your FGD. The new one fixes it, thanks! If I may, I'd humbly suggest the tool docs and FGD be updated to clarify the _samples description, which says "Default 16 (only used if "_deviance" is set)." I didn't understand that any value of _samples activates the feature regardless of the _deviance value. Thanks, Wiiki! (Can you guess where my username comes from? :P) Now I just need to figure out why the beta tools are producing maps missing some textures. I'm using ID1, lavacity1a, and mapjam666 wads, and a few textures from each are missing. Others load just fine. Switch back to 0.15.1 with no other changes and all the textures show up. Any ideas?  *sigh* Of Course...  #86 posted by ItEndsWithTens on 2015/08/12 06:27:51 ...as soon as I post I realize the problem isn't exactly as I describe. It looks like the texture thing I mentioned isn't spotty, I mistook a few textures as belonging to a different set. The problem looks like two of the three wads aren't being loaded at all, with only mapjam666 (the last one listed in worldspawn's 'wad' string) being used.  Yo  #87 posted by DaZ on 2015/08/12 14:45:11 The _samples thing iirc was a bug in the tools, the description was copied directly from Eric's site! It may already be fixed in his latest version of the tools. Making that fgd has certainly upped my appreciation for programmers, and how they make stuff compatible across different apps/versions! What a pain in the arse :D    #88 posted by Breezeep_ on 2015/08/12 21:31:26 http://i.imgur.com/jUcJ0Jn.png I'm not really sure why the Lighting FGD just adds these unnecessary entity keys to all the light entities in my map, and It's just tedious to remove all of these different keys.  These Seem To Be The Default Values For Those.  #89 posted by SleepwalkR on 2015/08/12 21:44:05 Are they actually in the .map file when you save it?  Default Keys Are Always Added  #90 posted by XaeroX on 2015/08/14 15:55:22 That's why they are called "default". :)  @ItEndsWithTens  #91 posted by ericw on 2015/08/14 22:28:00 I didn't understand that any value of _samples activates the feature regardless of the _deviance value. Crap, I forgot to fix that :-(. Will fix it and put it in the next beta. re: textures not loading with the beta, but working with 0.15.1, that is messed! Any chance you could send me the wads and map so I can double check what is going on? I don't think I changed anything that should affect texture loading.  Sure Thing!  #92 posted by ItEndsWithTens on 2015/08/14 23:04:36 Eric, I just sent you an email, thanks for the offer! You'll get the map, wads, and a readme with details. Hopefully I'm just doing something dumb. :)  What The Hell, Daz?  #93 posted by Breezeep_ on 2015/08/15 22:47:38 If I don't select every single light entity in my map, the lighting would end up like this: http://i.imgur.com/37pGUH0.png Honestly, I'm getting tired of being forced to select all the light entities and removing all the unnecessary entity keys for each light. Are there any workarounds for all this crap>  Well  #94 posted by DaZ on 2015/08/15 23:11:29 are you using the latest fgd I made? https://dl.dropboxusercontent.com/u/33279452/quake4ericwTools.fgd You don't have to use this fgd, there is a default one provided with Jackhammer. I made it for myself and thought others might find it useful!    #95 posted by Breezeep_ on 2015/08/15 23:33:17 Yeah, I'm using the latest fgd.    #96 posted by Breezeep_ on 2015/08/15 23:41:34 Is it possible to changing the defaults to 0?  Suggestion For A Dirtmap Setting  #97 posted by ptoing on 2015/08/15 23:42:07 Looking at this screenshot (also had a similar thing myself playing around with mapping recently) http://i.imgur.com/81RoXoQ.png You can see that there is AO applied at very shallow angles. Maybe something like -dirtangle [degrees] would be a good setting to add. Where of course stuff under that angle would not be dirtmapped or something like that.  Defaults  #98 posted by DaZ on 2015/08/15 23:47:58 All the values selected on the lights when you create them are the defaults.  The Default  #99 posted by FifthElephant on 2015/08/16 01:06:46 state for any light entity is 300 light. This is how it has always been.  Or...  #100 posted by ptoing on 2015/08/16 01:29:18 I guess not all of that stuff is from dirtmapping but just how light works. So maybe something that makes faces with angles under a certain threshold have averaged normals, basically like angle threshold controlled smoothing groups.    #101 posted by necros on 2015/08/16 01:38:47 you can reduce _anglesense below 0.5 to help alleviate the shading problem in that tube. it may make the light look a little odd because it won't attenuate based on face normal as much. might take some tweaking to look good.    #102 posted by ptoing on 2015/08/16 02:05:51 Is anglesense something you set per light?  Yo  #103 posted by DaZ on 2015/08/16 02:31:02 Yes you can set it per light with _anglescale. The default is 0.5    #104 posted by ptoing on 2015/08/16 02:35:22 Thanks :) Will play around with that when I got time.  Yep  #105 posted by ericw on 2015/08/16 02:39:43 you can set "_anglesense" per-light. When I get a chance I'll try playing with normal smoothing again. The first time I tried it I was still getting hard edges, e.g. with sunlight shining on an octagonal pillar.    #106 posted by ptoing on 2015/08/16 02:50:14 It's too bad you can not assign any values to brushes, that way it could be controlled on a brush basis, which would make more sense from a user perspective. But having it as a global variable with an angle threshold should be enough I think. Maybe additional value for func_walls, func_detail and such might make sense.    #107 posted by necros on 2015/08/16 04:46:44 ericw: normal smoothing?? so like phong shading? that would be insane.  Ericw  #108 posted by FifthElephant on 2015/08/16 04:52:47 phong shading would be sweet... how will it be implemented though? Quake 2 allows surface flags to be set but there's nothing like that in Quake 1.  Super Hacky Way Of Doing Shit...  #109 posted by ptoing on 2015/08/16 05:02:01 might be to do it via textures. Basically have a version of the level which you just use to generate smoothing group data and compile before the other stuff or something. You could just have it be a bunch of textures that correspond to SG01, SG02, SG03.. That would probably be a pain in the ass to do though. Just plopping out dumb ideas here. Or it could be integrated into the editor somehow, which just generates some file based on which faces the user has combined into a smoothing group.  Half-Life  #110 posted by DaZ on 2015/08/16 05:16:19 HL's light compiler uses Phong to shade smooth curves. You can also setup "smooth groups" in hammer that can tell the compiler what brushes to perform smooth lighting on. A good place to start!  A Long Long Time Ago  #111 posted by damage_inc on 2015/08/16 07:26:36 I think I remember playing around with WC and you could assign a value(-1?) to a brush face(I used an octagon) and then when you compiled the map you could not see any hard edges? If you looked at the floor you could tell it was an octagon but otherwise no. Am I crazy or does anyone else remember this?  Damage_inc  #112 posted by - on 2015/08/16 07:51:35 Are you thinking of Quake2 mapping? because ArghRad added a feature for phong shading via that method. Quake2 let you specify surface properties per face, so you could stick values into properties to set up smoothing groups for the compiler. (IIRC, you set a brightness value for the face as the smoothing group number, but didn't turn on the face's 'emits light' flag and ArghRad would look for that pattern) Quake's .map format doesn't support any per face values, so there's no place to store any values for the compiler to know which faces to smooth.  Ohhhh... Yes Scampie  #113 posted by damage_inc on 2015/08/16 08:48:58 That's it! Now I remember, it was When I was teaching a friend Quake2 mapping. Thanks.  DaZ  #114 posted by kaffikopp on 2015/08/16 17:17:45 Trying to use your fgd with Hammer (not Jackhammer) causes it to crash. Any idea why this occurs? The standard fgd by czg works fine.  Hmm  #115 posted by DaZ on 2015/08/16 23:10:48 I haven't tested it with Hammer at all, I imagine there some syntax craziness going on!  What Do These Error Messages Mean?  #116 posted by former_total_newbie on 2015/08/21 23:52:30 *** WARNING 12: New portal was clipped away in CutNodePortals_r *** WARNING 16: Texture __TB_empty not found I got them while compiling a TB2-made map using qbsp from this branch. I've been compiling every so often to test things out and I mostly do not get any errors. Would just like to know what I could have changed that would have resulted in these errors (and hence what I should avoid doing in future).    #117 posted by Rick on 2015/08/22 00:10:05 CutNodePortals_r is usually caused by complex brushwork, often occurs where several planes meet at one point and/or there are brushes with vertexes off the grid. If it gave coordinates, look there in your map to see what could be the cause. Example, txqbsp_xt will report it like this: WARNING:CutNodePortals_r: new portal was clipped away near (2592 -518 -40) Texture TB_empty sounds like some kind of missing texture error where TB substituted "Texture __TB_empty" in it's place of its name.    #118 posted by Rick on 2015/08/22 00:15:42 Depending on where it is, you can often just ignore a CutNodePortals_r warning, but sometimes it causes small invisible walls that'll block player movement. Turning complicated brushwork in the area of the warning into func_walls will also sometimes fix it. I got a lot of this in my jam6 map due to the weird brushes making the damaged walkway, so I just made them a func_wall.    #119 posted by - on 2015/08/22 00:21:14 "__TB_empty" is the texture name Trenchbroom puts on a face with no texture. If you know the brush, you put a texture on it, if not, do a find/replace in notepad or something and search for "__TB_empty" and replace it with some other texturename (Does TB/TB2 have a texture find/replace? if so, use that)  __TB_empty  #120 posted by SleepwalkR on 2015/08/22 00:22:03 is used when you have a face without a texture. TB2 has to insert some string as the texture name, and this is the placeholder it uses for such situations.    #121 posted by ma†echa on 2015/08/22 00:36:39 "" is a string, no? :) :) :) srsly tho, yeah, I opened my .map in Sublime Text and did a find/replace  Thank You Very Much, Rick, Scampie And SleepwalkR  #122 posted by former_total_newbie on 2015/08/22 00:38:28 ...for both explaining what causes those errors and giving me pointers on how to fix them (or potentially work around them, in the case of CutNodePortals_r).  Matecha  #123 posted by SleepwalkR on 2015/08/22 00:41:29 Texture names are not quoted in the map file. God knows how different compilers would interpret "".    #124 posted by - on 2015/08/22 00:48:36 Radiant uses a blank space, luckily it also recognizes that blank space as something you can find and replace in the editor.  Ericw  #125 posted by Rick on 2015/08/22 01:17:14 By the way, my favorite new feature of the light utility is the ability for func_walls to cast shadows. I used it a several times in my jam 6 map. The 12 fingered torchieres in the lava and the hanging lanterns beside the last steps up are all func_walls casting cool looking shadows.    #126 posted by ericw on 2015/08/22 01:23:48 I think Tyrann added that, but yeah it's awesome!  Agreed  #127 posted by - on 2015/08/22 01:30:11 I used "_shadow" key quite a bit... but there's one obvious spot where it caused an issue that I should've worked around: A func_illusionary with "_shadow" "1" on the floor casts blackness on the floor below it, so any dynamic entity on top of that func_illusionary will be unlit because it uses the lightmap of the solid floor (which is fully shadowed) as the brightness of the entity above it. This isn't a compiler problem, it works as intended, but can be unexpected that that is how it works. This is why there is a fully dark Ogre in the map. I had to do that because of a clipping error, but I should've tried some other things to fix it, but it was getting really close to the deadline.    #128 posted by Rick on 2015/08/22 02:11:18 That's similar to the old "black scrags against a bright sky" thing that many maps suffer from. To fix that particular problem you had, sometimes you can put a func_wall floor underneath to catch the shadow, then put a real floor below that which is lit normally to provide the entity lighting. But it can be tricky to get the brightness balanced. Yeah, that deadline was a pain :)    #129 posted by necros on 2015/08/23 20:12:23 been meaning the mention this... -fast is missing from light.exe... Could we have this back, since it can take 20-30 minutes to light stuff now with all those deviant lights and such...    #130 posted by necros on 2015/09/09 22:48:37 Any way to attach a lightstyle to a shadow from a bmodel?  Haha  #131 posted by ericw on 2015/09/10 01:00:35 I think that might actually be possible. It would be a bit of work to code, possibly not too bad though.    #132 posted by necros on 2015/09/10 01:21:31 cool, it's just a nice-to-have. maybe you have some floor you want casting shadows, but later needs to break or something...  New Build Soon?  #133 posted by czg on 2015/09/16 09:11:03 There's a fix for mixed face contents I'd like to have that was added to git on 31/07, but the latest build is from 13/07 (according to readme). Will there be a new build soon-ish or will I have to do it myself? (= pain)  There Are Nightly Builds  #134 posted by SleepwalkR on 2015/09/16 10:51:42 available from here: http://quakespasm.ericwa.com/job/tyrutils-ericw/  Yay! Excellent!  #135 posted by czg on 2015/09/16 11:05:24   Czg:  #136 posted by ericw on 2015/09/16 21:43:59 Yeah, those nightly builds should be fine to use. In other news I found a serious bug in the surface lights code that was causing it to spam multiple copies (sometimes 10+) of each of the surface lights. This is unrelated to the bug where setting "_deviance" "0" on a surface light would also spam copies.. This explains why they were going crazy for some people during the map jam, and the extra long compile times with surface lights. That should be fixed in the nightly builds. I'm working on some speedups for light right now and hope to have a new release soon.  New 0.15.2 Build  #137 posted by ericw on 2015/09/17 08:21:54 available on the website: http://ericwa.github.io/tyrutils-ericw/ Changes: * qbsp: add "-maxNodeSize" option, from txqbsp-xt. Defaults to 1024. Makes large maps process much faster and should generate better bsp trees. If it causes a problem disable with "-maxNodeSize 0" * qbsp: make "mixed face contents" and "degenerate edge" non-fatal, from txqbsp-xt * qbsp: make "-oldaxis" the default. new "-nooldaxis" flag to get the previous behaviour. * light: add "-surflight_subdivide" flag to control amount of surface lights created * light, vis: use below normal process priority on Windows * light: allow negative surface light offset * light: average the lit file color components to generate the bsp lightmap value. TODO: use a perceptually weighted average. * light: fix lighting of hipnotic rotating entities. * light: fix crash in "Bad texture axes on face:" * light: fix surface lights being mistakenly duplicated * light: add "-onlyents" * light: add "-dirtangle" setting to control dirtmapping cone angle, default 88 degrees.   Yes Yes Yes  #138 posted by FifthElephant on 2015/09/17 11:17:20 But what about phone shading!!!    #139 posted by JneeraZ on 2015/09/17 12:23:26 Apple or Android?  Hexen2 Support Patch  #140 posted by Spike on 2015/09/18 16:26:28 http://triptohell.info/moodles/junk/tyr-h2.patch adds -hexen2 argument to qbsp to generate a h2(mp) bsp. vis and light also accept hexen2 bsps. doesn't do anything about palettes. silently ignores hexen2's extra 'light' attribute of each plane, if specified. this is consistent with other hexen2 tools (iiuc). doesn't do any special behaviour with watervis, so unlike hexen2 lava is watervised by default. do NOT try loading a hexen2 bsp in a quake engine (other than ones that explicitly support it). doing so will likely result in crashes (and vice versa). -hexen2 -bsp2 are accepted simultaneously. fteqw supports this, other hexen2 engines will need to be tweaked now that there's a tool that can actually generate them. this relaxes the clipnode limit that otherwise severely limits the sizes of hexen2 maps (to two fifths of a quake map, approx). let me know if I broke anything...  Spike  #141 posted by ericw on 2015/09/18 20:14:33 wow, thanks! this will be nice to have. I will test this a bit and merge it in. ExportClipNodes is confusing, I don't get what the "diff" variable is doing and why was it only modifying model->headnode[1], but it will probably be clear if I watch it in the debugger.    #142 posted by Spike on 2015/09/18 22:06:21 yeah, that took me a while to figure out too... its reordering the clipnode trees because they're calculated by hulls then models, but stored in the file as models then hulls, so the previously stored hulls need to be remapped to cope with the clipnodes added into the previous models (ie: clipcount has changed since the tree for the previous hull was generated). the alternative would be to store the trees as-is and fix them up later. I forgot to do anything about world.spawnflags&1 signifying mission pack+hulls. I'm not sure that there's much point in it not being set, but meh.    #143 posted by gb on 2015/09/24 22:22:20 Hexen 2 bsp2 support - cool, I might finish my big H2 map then. I considered using it elsewhere but it doesn't really match there either. It has been just collecting dust since it broke the format like a clumsy child breaks eggs. :-/ just like my ROEM maps have been collecting dust since I got vaguely pissed off with RMQ gameplay and Quake at large but was too bored, sick, busy to do much about it. Can't puzzle out the gameplay but also can't release them for vanilla quake (too big, too spacious etc) anyway, hordes of fucking archer knights, at the ready? I'll have to try H2BSP2 some day. uh, Hexen 2 jam in honour of this feature? Or am I hallucinating. I probably am. No one makes Hexen 2 maps anymore.

Might it be worth putting in a -nodetail switch or something that lets you do a test compile that discards all the detail brushes, allowing you to find leaks that are purely in the (non-detail) world brushes?  Kinn  #145 posted by FifthElephant on 2015/10/04 10:08:55 If you're using TB you can actually hide certain brushes. Just go to the View tab on the right and deselect Detail Brushes.  Fifth  #146 posted by Kinn on 2015/10/04 13:12:39 I use Netradiant, and never could get into TB unfortunately (although I like the sound of TB2 - I may have to have a goosey at that).

However, I never like the idea of restricting the choice of editors, and I know plenty of us are using an editor that is no longer in active development (e.g. netradiant) and really want to stick with it, so is it worth talking about a compiler-side prefab feature? The user interface would be simple - a "func_prefab" entity with a key that points to the filepath of a .map file containing whatever you want copying over. Rotation should work as expected. I don't think scaling would get used as much but that might also be worth supporting Of course in old editors you'd lose the ability to see the geometry in your map, but in a lot of cases I don't think this would be much of an issue as you'd position the brushes in your prefab map file so that a sensible anchor point would be at the origin. Thoughts?  The Problem With A Posteriori Transformations  #154 posted by SleepwalkR on 2015/10/10 15:38:59 Is how to ensure that the textures are still aligned. Translation is easy, scaling is not so easy, and rotation is a bitch. Also difficult are targetnames etc.  In The Last Map Jam  #155 posted by ericw on 2015/10/10 19:00:34 someone mentioned having written or used such a tool on their jam map. Seems like a great idea to me, I also like making it a standalone tool so it's not tied to one editor or compile tool. Sleep- one idea to help with texture alignment is to have the postprocessing tool convert the map to Valve 220. That should make it easier to preserve texture alignment. Since it's a postprocessor it doesn't matter if you editor can read 220, and all qbsp's these days can.  I Knew My Ears Felt Hot  #156 posted by ItEndsWithTens on 2015/10/11 00:19:19 Eric, I didn't think anyone was paying attention when I mentioned that during the last jam! :) The "someone" in question was me. Over a couple of days before map jam 6 I hacked together some changes to Metapyziks' "VMFInstanceInserter", and while building "Princess of China" used it to place the light fixtures, skin bridges, totems, and of course googly eyes. VMFII was built to allow the use of the func_instance entity in branches of the Source engine whose tools don't natively support it, namely Half-Life 2 and its episodes. With the map and FGD file formats of Source being based, as they are, on the Quake/Worldcraft tradition, I figured I could simply conform both types of files to the expected formats on input to VMFII, then postprocess them back to Quake land before spitting out the results. It seems to have worked out, and saves the trouble of duplicating an entire codebase of translation/rotation code. The .map branch of my fork of the project can be found at https://github.com/ItEndsWithTens/VMFInstanceInserter/tree/add_map_support if you're interested. Github makes it easy enough to get back to the upstream project if you want to look at that, and you can see https://developer.valvesoftware.com/wiki/Func_instance for more details of how instances work in Source. As for features, name fix up works just fine, prepending or appending a name (either one of your choice or an automatically generated unique) to your entity connections to make sure each instance remains separate, and variable replacement is no different. The func_instance_parms, _io_proxy, and _origin entities mentioned on that SDK Docs page don't work, mind you, but that's not unique to my Quake additions. There are some caveats: -I haven't released any binaries of my custom changes yet; I could always run off a few private builds for testing, but I haven't yet contacted the original developer to see if he's receptive to support for other games, or if he's satisfied with my approach in the event he is. -I haven't updated the documentation, and there's a bug in Jackhammer I just realized I forgot to mention in its respective thread that keeps this tool from working conveniently there. -The program is written in C#, so running it in Linux/OSX is sure to be tricky. What research I've done suggests it's not impossible, though, especially without any GUI libraries to worry about, and I have access to a Mac Mini with the latest OS X and as many Linux VMs as I have disk space for, so I can certainly take a crack at building it there. -There's no scaling support. I don't have enough 3D graphics theory under my belt to even begin tackling a thing like that, and I don't know what effect it might have on Source instances (which don't support it either) in any event, so I don't know how realistic this one is. -My code currently requires the Valve 220 .map format, but really just because that's what Jackhammer produces, and I was building my map in that editor. I can take a look at adding a little something to handle other types of map, I suppose.  Oooh!  #157 posted by Kinn on 2015/10/11 00:36:03 That sounds very interesting! PS: I wouldn't bother with scaling - I mean there might be some situations where you might want to scale a prefab (e.g. the depth of an arch) - but you've got to worry about what the textures do on the surfaces that get affected by the scaling (e.g. inside of the arch), and you're probably better off just making multiple prefabs to cover the small number of scale variations that you'd want.    #158 posted by ericw on 2015/10/17 20:11:14 The dev builds now have Hexen 2 support ("-hexen2" flag for qbsp. Thanks Spike!), and also the qbsp "-epsilon" flag from txqbsp. http://quakespasm.ericwa.com/job/tyrutils-ericw/    #159 posted by ItEndsWithTens on 2015/10/19 22:04:10 I'll start a dedicated thread around here eventually, so as not to hijack this one, but I thought I should mention I finally got around to cleaning up and releasing the instance thing I talked about. The changes I made to that other project, VMFII, turned out to be awfully clumsy implemented that way, so I turned the code into its own wrapper project. Curious parties can try out Quinstance from the releases tab of its Github page: https://github.com/ItEndsWithTens/Quinstance Instructions are included, have fun!    #160 posted by FifthElephant on 2015/10/19 22:21:34 So it's almost like how external bsp's are used as bmodels?    #161 posted by ItEndsWithTens on 2015/10/19 22:34:25 I'll tentatively say yes, I believe it's something like that, but I've never worked with bmodels before, only heard vague whisperings of their existence. I think the best way to describe it is that it's like using prefabs, but any changes you make will automatically be applied to every instance you've already placed, and using a standalone tool means it's editor and compiler agnostic.  Nice!!  #162 posted by ericw on 2015/10/19 23:00:05 Can Jackhammer render a preview of the func_instance? That would be crazy.  If This Becomes The Agreed Upon Standard Solution  #163 posted by SleepwalkR on 2015/10/19 23:06:23 I'll add support to TrenchBroom 2 as well.    #164 posted by ItEndsWithTens on 2015/10/19 23:15:43 Sadly no, eric, you don't get a preview in Jackhammer. I only focused on JH when building the included FGD because it's the editor I was using. Positioning things can be slightly irritating when you can't see what you're placing, but keeping Quake running in a window makes it easy to adjust/recompile/reload/repeat, so it's workable. Of course I'd love to see actual display of the instance contents, but it's just wishful thinking for now. SleepwalkR, that sounds wonderful! Bear in mind I'm not trying to present this as the be-all end-all solution, just one I found useful for my own project. If someone comes up with a better way to do things, I'd be just as happy to use that.  Tens  #165 posted by adib on 2015/10/20 17:08:35 a copy of the other map's contents will have appeared where the func_instance once was Are they aligned by their center coords? If this is the case, I would probably try to make func_instance a brush entity of the same size as the prefab, like a bounding box. That would help keep things on grid.    #166 posted by ItEndsWithTens on 2015/10/20 17:30:54 Ah, thanks for the question, I'll need to clear this up in the documentation. The instance contents are not positioned based on their collective center, no. The center of the point entity and the origin of the instance map are lined up. All objects in the Filename map get offset from the func_instance by the same distance they're offset from their own map's origin, so it's reasonably straightforward to predict where things will be when all's said and done. The Source engine tools' version of instances does have a func_instance_origin that lets you define a custom origin, actually, but VMFII doesn't yet implement that, so it won't work with Quake maps until that changes. I should have a News post written up in a few minutes, so if it's accepted we can take further discussion over there. Hang tight!  Cool Little Optimization For Vis  #167 posted by ericw on 2015/10/20 23:05:49 When using func_detail, you have leaves (subdivided volumes of the map, including func_detail) and clusters (volumes ignoring func_detail). The vis speedup when using func_detail comes from vis only looking at portals between clusters. What it was doing before was writing a copy of the visdata for a cluster for each leaf in that cluster - I just changed vis to write a single copy of the visdata for each cluster, and then all of the leaves in the cluster reference the same visdata offset in the bsp file. All this really does is shrink the bsp file (telefragged.bsp is 10mb smaller) and maybe load a tiny bit faster as a result, but it seems like a nice optimization. Seems to be safe with old engines (winquake.exe) too.  Neat!  #168 posted by ijed on 2015/10/21 07:45:51   I Think I've Asked This Several Times Before But I Keep Forgetting  #169 posted by czg on 2015/10/23 01:44:50 Does light use the pvs data (if present) in any way to speed up traces?    #170 posted by metlslime on 2015/10/23 02:11:15 i believe that was true in quake 2 light compilers, but not quake 1. (unless somebody added the feature to quake 1 light compilers)    #171 posted by ericw on 2015/10/23 07:28:07 czg, my light tool doesn't use vis data. I experimented with it a while ago, but the code was messy and I couldn't get much speedup from it. I could have been testing the wrong map (was trying telefragged.bsp). It probably would help if there are a lot of delay 2 or infinite lights, but also good vis blocking. another idea I had is to shoot a bunch of random rays from each light, and use the furthest distance hit as a bounding sphere for the light, sort of a rough guess at the pvs. haven't tried this, though.    #172 posted by Lunaran on 2015/10/23 07:42:04 is minimum intensity contribution as bounding sphere already implemented? once a delay 2 light drops below a half percent intensity or so it might as well be cut off anyway, right?  Yeah  #173 posted by ericw on 2015/10/23 08:00:30 That's implemented, the -gate option. I think "-gate 1" means to cut off lights when the brightness would be 1/255.    #174 posted by JneeraZ on 2015/10/23 08:11:17 I think enabling the multithreading a few years back was the most significant speed boost to light.    #175 posted by ericw on 2015/10/23 09:48:08 Warren, yeah, for sure, the threading is amazing. Lunaran: lol, you prompted me to take a closer look at the "-gate" switch, and seems it was broken in�tyrutils (was calculating a bounding sphere that was too large). I was wondering why using like "-gate 25" wasn't speeding up maps with lots of delay 2 lights. I think I fixed it..  Right, So There's No Gain From Running Vis Before Light Really  #176 posted by czg on 2015/10/23 11:39:51     #177 posted by - on 2015/10/23 17:45:11 I've been using -gate 10 forever... are you saying it's done nothing forever!? :(    #178 posted by Rick on 2015/10/23 18:10:55 I asked several times in the past about what exactly the "gate" number referred to and what was the range. I never really got a good answer. My working theory is that it's the rgb value of the lightmap, 0-255. So if you set -gate to 20, everything below that is pure black? Or am I totally wrong. What always threw me off was that many references state the default value is 0.01 or some other nonsense.  Scampie, Me Too!  #179 posted by mfx on 2015/10/23 18:29:52 Gate -10 seems to light faster than gate -1. A tiny bit.  Correction  #180 posted by mfx on 2015/10/23 18:57:42 -gate 10 versus -gate 1.  Scamp/mfx  #181 posted by ericw on 2015/10/23 19:29:26 I think it's been broken since it was added to tyrutils in 2013. If you have a map with lots of delay 2/5 try the devbuild in #158. On jam6_ericwtronyn I get a huge speedup, like: No gate: 60s, gate 5: 7 seconds    #182 posted by - on 2015/10/23 20:18:25 Wow, yeah, map I'm working on went from 18secs to light to 8 seconds (only option was -gate 10) nice!    #183 posted by - on 2015/10/23 20:21:37 ...though it seems -gate 10 is a bit high of a setting now that it actually works, lost a lot of detail in my lighting :D Still, nice that it actually works!  Yes  #184 posted by mfx on 2015/10/23 20:24:24 2 times faster now with -gate 10.    #185 posted by Lunaran on 2015/10/23 21:23:30 so, what does the number after gate actually mean then?    #186 posted by ericw on 2015/10/23 21:49:39 When you specify "-gate X": for each light, the util calculates the distance at which a surface would be lit up by that light to an intensity of 'X'. The intensity units are the same as the bsp file, so 127 is full brightness, 255 is 2x overbright. The distance calculated is used as a bounding sphere, so beyond the sphere the light casts 0 brightness.    #187 posted by ericw on 2015/10/23 21:53:10 Scampie + mfx, awesome it is giving a speedup for you guys! If you just have a delay 2 light in a large box room, "-gate 10" should give a visible seam where the brightness changes abruptly from 10 to 0. Might have to turn up the quake gamma to see it clearly. It's possible I still messed up the formula so i might try rewriting it in a more straightforward way.    #188 posted by - on 2015/10/23 22:26:23 I found -gate 3 worked well for my situation. Still a large speedup and I keep some of the subtle lighting effects I was doing.    #189 posted by PuLSaR on 2015/10/23 22:35:39 i remember -gate 1 got a great speed up on old rigs in aguirRe's tools. like from 10 minutes to ~10 secs. Was is different now?    #190 posted by Lunaran on 2015/10/24 05:22:34 127 is full brightness, 255 is 2x overbright. That's what I was wondering, thanks.  PuLSaR  #191 posted by ericw on 2015/10/26 05:55:56 Tyrann just added -gate more recently to his tool (2013), and it looks like there was a bug causing it not to give as much of a speedup as it should have. but it's fixed in the most recent dev build of my version of tyrutils.  New Release V0.15.3  #192 posted by ericw on 2015/10/26 21:51:57 https://github.com/ericwa/tyrutils-ericw/releases Highlights are Spike's addition of Hexen 2 support, fixed -gate, a new "_surface_spotlight" key which automatically sets "mangle" on surface lights to turn them into spotlights.  I've Just Tried It  #193 posted by PuLSaR on 2015/10/26 22:29:05 and -gate really speeds up the light process  _surface_spotlight Sounds Neat  #194 posted by mankrip on 2015/10/27 02:45:36 Also, a question: Does surface lights follows the shape of the fullbright texels, or maybe the luminance of each texel?  No  #195 posted by ericw on 2015/10/27 03:12:22 The "surface lights" I implemented are nothing fancy like that, all it does is handle cloning & positioning copies of point lights. It's just a shortcut around a lot of copy&paste really. It works best with runic light fixtures where it'll reliably put a single point light on each light fixture. The q2/q3 light utils have "real" surface lighting, where the light-emitting surfaces are divided into radiosity patches, and then the area of these patches is used in the lighting calculation. See here in the q3 tools. I think the patches took their colour from an average of 32x32 texels or something. I did experiment with that code in my tool but didn't have the greatest results, it was slow, tended to cause "hot spot" artifacts on the walls around a lava surface, and generally didn't look very good in Quake.    #196 posted by mankrip on 2015/10/27 04:14:13 :) Thanks for the info. Idea: Interpret the fullbright texels as transparent, and put the surface's point light behind the surface. This way, you can use the algorithm of the alphamasked texture shadows to shape the light. The results will be more akin to spotlights, so it would have to be optional. It would be useful for stuff like windows.    #197 posted by - on 2015/10/27 05:01:05 That seems like a really fun feature... I'm going to make a crazy disco ball of spotlight lasers    #198 posted by Spike on 2015/10/27 05:12:30 mankrip, windows like http://triptohell.info/moodles/junk/fte-20150311190731-0.jpg really needs .lit2 type stuff :s  0_O  #199 posted by mfx on 2015/10/27 05:23:48 That screenshot is nice!  Surface Lights  #200 posted by oGkspAz on 2015/10/27 09:13:21 Considering my lighting knowledge is terrible at best, here's the bit where I go: "I've seen surface lights mentioned but how does it work?"  Spike  #201 posted by FifthElephant on 2015/10/27 11:24:40 that screenshot reminds me of something that I experimented with. http://quakeguy.tumblr.com/post/120732856652/stained-glass-window-casting-light I have a feeling that however you did it might be more competent because you have managed to get the actual texture to look like it's projected, whereas mine is a bit more of a hacky workaround using alpha masked textures and a couple of different coloured lights.    #202 posted by JneeraZ on 2015/10/27 12:03:16 _surface_spotlight sounds cool. So it just sets a spotlight based on the surface normal or something?  Looks Noice But  #203 posted by Kinn on 2015/10/27 12:35:48 Stained-glass window lighting to me always looks exactly like those rainbow-splatter lightmap glitches you'd see in games from the early 2000s that remind you that you need to update your OpenGL drivers.  Warren  #204 posted by ericw on 2015/10/27 19:35:37 Yep, it sets the spotlight based on the surface normal. It's just a little convenience thing, I always found setting "mangle" to be a pain. This way you can rotate the light fixture brushes any angle and the spotlight will always shine the correct direction. :-) oGkspAz, there's an example screenshot + entity at the bottom of: http://ericwa.github.io/tyrutils-ericw . Basically add key/value "_surface" "texname" to a light entity, and copies of that light will be cloned on all faces with that texture name.  @ #200  #205 posted by - on 2015/10/27 19:41:21 Surfaces lights in these tools are pretty simple things. You place a light, anywhere in the map, and put whatever _color and light and delay settings you want on it... you then put "_surface" "NAME_OF_TEXTURE" on that light, and the light compiler will automagically copy that light around just in front of any surface with that texture, spaced apart every 128 units. It's best for things like textures that are clearly light sources, a nice convenience so that you can mess with a single light once, and all of them will be lit up. It can also be good for something like Lava, and doing the legwork of lighting it all up for you.  Minor Promble  #206 posted by Kinn on 2015/10/27 21:06:35 A minor thing though is that if BSP chops your surface up, you get a new light for each face which can make things brighter than expected in places. This seems to be a problem with liquid surfaces mainly.  Yeah  #207 posted by - on 2015/10/27 21:44:23 I like placing the lights myself for lava, gives better control.  Scampie  #208 posted by mankrip on 2015/10/27 21:51:06 Thanks for the 128 units clarification. I wanted to ask that before, but couldn't formulate the question properly.    #209 posted by mankrip on 2015/11/04 10:54:08 I don't know if there's an option for this already, but it would be cool for the dirtmap to be sized accordingly to the angle of the surface. This way, it would give a better impression of being dirt, since it would appear to have been affected by gravity and friction (horizontal surfaces gets the most dirt, vertical surfaces gets the least dirt). Implementing this through an adaptive -dirtgain would probably be enough. -dirtscale would have to remain the same, to ensure equal shading at the edges.  Antilights Broken?  #210 posted by Kinn on 2015/11/07 19:23:41 As far as I can tell, antilights (lights with negative value) no longer work - can anyone verify? I was using quite a few of these :{  Argh  #211 posted by ericw on 2015/11/07 19:27:59 I'll check it out - I never test those, but hopefully it's easy to fix.  Cheers  #212 posted by Kinn on 2015/11/07 19:34:14 to elaborate: One of the things I made use of before were antilights with a "style" value - crucially these only subtracted light from other lights with the same style value.  Kinn  #213 posted by onetruepurple on 2015/11/07 19:44:36 Are you using minlight?    #214 posted by ericw on 2015/11/07 20:05:51 Ok, they should be fixed in the dev build: http://quakespasm.ericwa.com/job/tyrutils-ericw/ I just made a mistake when reworking the light culling in the last release (to make -gate give a proper speedup), and it was culling all of the antilights. The special behaviour of style should still work. I didn't realize they would work that way at first, but it makes sense, because whenever a light with "style" set hits a surface, there's a new lightmap allocated for that style number - so a negative light with that style number would only affect that separate lightmap.  Awesome  #215 posted by Kinn on 2015/11/07 23:00:46 Thanks!  Thats A Neat Idea  #216 posted by ijed on 2015/11/09 14:36:25   _surface_spotlight Workaround  #217 posted by dumptruck on 2015/11/18 08:30:59 It seems like when _surface_spotlight is set in the entity the actual surface no longer illuminates as it would without. Is there a work around or is this a bug?  I Think That's Intended  #218 posted by ericw on 2015/11/18 09:23:31 To get a regular surface light in addition to the spotlight, just have two template entities, one with and one without _surface_spotlight set. You can have multiple lights with the same _surface value :)  Slapping Forehead!  #219 posted by dumptruck_ds on 2015/11/19 05:59:48 Thanks that will work - and it totally makes sense.    #220 posted by mankrip on 2015/11/20 14:18:58 I think dirtmapping should not be applied in points where there's a light close by, 16 or 32 units maybe. The low resolution of the lightmaps makes small surfaces in cramped places close to a light go fully dark.  #220  #221 posted by Kinn on 2015/11/20 14:42:52 Hehe, I was thinking something similar, but it needs to be controllable per light. Remember you can work around all the issues currently by using _nodirt on a per-light basis. However, that requires more light ents to be added, which may get fiddly and annoying as the map scales up. A way of doing what you are saying would be to introduce a _nodirt_radius key on a light, which means the light gets "dirty" as normal except on surfaces within (_nodirt_radius) from the light. the transition between nodirt and dirt needs to be blended in as well to avoid ugly transitions. Ugh, maybe another key is needed to define when the blend starts :/  _nodirt Didn't Work  #222 posted by mankrip on 2015/11/20 16:21:15 � but _dirt -1 did! \o/  Mankrip  #223 posted by Kinn on 2015/11/20 16:26:28 sorry I forget the names of the keys, I think they have changed once or twice as the feature developed    #224 posted by mankrip on 2015/11/20 17:29:10 No problem; I'm still using my custom version from when I implemented lit water support.  V0.15.4 Released  #225 posted by ericw on 2015/12/11 02:06:32 change list & downloads: https://github.com/ericwa/tyrutils-ericw/releases Mostly bugfixes, except there is a new _sunlight3 that comes from the bottom hemisphere, instead of the top (_sunlight2). This is mostly for maps floating in the clouds, where you want skybox under the map that emits light. Combine both sunlight 2+3 for light coming from all directions, and use two different colors for crazy effects. Also, the -parse_escape_sequences option for light is a gimmick that lets you make red text in door/trigger messages, which previously you could only do with custom QC.  Updated Jackhammer Fgd  #226 posted by DaZ on 2015/12/11 11:44:53 added the _sunlight3 stuff to worldspawn https://dl.dropboxusercontent.com/u/33279452/quake4ericwTools.fgd  Cools Stuff  #227 posted by Breezeep_ on 2015/12/11 22:06:31 I'd like to see a little demonstration of the new _sunlight3.    #228 posted by Lunaran on 2015/12/12 00:59:20 I added to my privately hacked tyrlite branch a "domelight" (this was pre-sunlight2), with control over color and intensity coming from straight up, the horizon, and straight down, blending between them (even though I'm not really working on a map that would take advantage of that.) There's enough ways to light a world from the sky that moving stuff like this from infinitely numbered worldspawn keyvalues to a light_sun entity would be prudent, except for the "no spawn func" errors it would produce. Does stripping an entity from the bsp seem dangerous or counter to some method of production? How often do people really re-light a BSP without re-BSPing it first?    #229 posted by metlslime on 2015/12/12 01:15:13 info_null is ignored by the game engine, so you could have an info_null full of sun properties. But is it really better than just putting it on the worldspawn?  Put Them In A Light Entity  #230 posted by Kinn on 2015/12/12 01:30:02 and flag it with a special key (eg _sun: 1) to tell light.exe that this is just your holder for the sun properties and not a normal light classname: light _sun: 1 _some_cool_sun_property: 21.463 I have spent maybe 2 seconds thinking about this, so there may be a better way.    #231 posted by Kinn on 2015/12/12 02:00:12 is it really better than just putting it on the worldspawn? Just feels cleaner to keep the sun properties encapsulated in a single dedicated entity that you can copy 'n' paste between maps easily. Also, getting a bit carried away with this...but with a sun as its own entity - you could support multiple suns by having multiple entities.  One More And I Will Shut Up  #232 posted by Kinn on 2015/12/12 02:07:32 To make setting the sun angle easy you could just target your sunlight entity towards an info_null, to implicitly specify the direction of the light (the setup would look like a cute little solar system)    #233 posted by adib on 2015/12/12 02:33:08 Multiple sun entities instead of _sunlight2, _sunlight3, etc?  Lun  #234 posted by ericw on 2015/12/12 03:04:24 Cool, blending the colors/intensity was something I wanted to try and will probably test out. control for the horizon is a good idea too. If I'm going to add a new, tidier way to specify sun settings, I would be tempted to do it properly and make new entity types (light_dome for _sunlight2/3, light_sun for regular sunlight), and then strip them out when writing the bsp. Even the way surface lights are currently specified is sort of a hack, it should be a "light_surface_template" classname or something. If anything is being stripped when light writes the entities to the bsp, it might make sense to make the light tool read entities from the .map file rather than the bsp, this would avoid a failure in case you ran "light" twice in a row. It would also mean you can skip the "qbsp -onlyents" when iterating on lighting settings, which could save a few seconds.    #235 posted by Lunaran on 2015/12/12 05:54:20 with a sun as its own entity - you could support multiple suns by having multiple entities. This is what I was thinking. Although, as someone with experience lighting a map with a fuckload of suns, beyond a very limited point (like two or three, which we have now) the line between imperceptibly subtle and clownishly gaudy seems to get pretty narrow.    #236 posted by necros on 2015/12/12 06:42:57 i'd like to have the ability to map lightstyles to sunlights... then you could have 4 'suns' that are always off, and flicker them randomly via QC.  #236  #237 posted by mankrip on 2015/12/12 06:56:47 Yes! For thunder & lightning effects!  Yeah  #238 posted by ericw on 2015/12/12 08:05:47 that would be sweet. I think it's easy to do in terms of the lighting code, the only challenge is how to expose it to QC. That's probably another argument for using entities for sunlight, it could work the same as ordinary lights; if the mapper sets "targetname" on the sunlight entity, the compiler assigns it a lightstyle.    #239 posted by Lunaran on 2015/12/12 09:49:29 I tried lightning tied to a skybox change a while ago, but every engine's got its own console command for the skybox and they're not consistent :/ You'd hit that 'max lightstyles for a face' limit quick though.    #240 posted by Spike on 2015/12/12 09:59:55 yay for shadowmaps and rtlights...    #241 posted by JneeraZ on 2015/12/12 10:31:42 Moving all features that affect the world into entities would be neat. "sky_fog" entity or something for easily copying fog between maps, etc...    #242 posted by mankrip on 2015/12/12 13:28:03 Suggestion: use the classname "info_world".    #243 posted by mankrip on 2015/12/12 13:31:50 And "info_world_sun", "info_world_fog", etc. in case of different entities for different features. Just to make it clear that such entities are global effects, not local effects.    #244 posted by FifthElephant on 2015/12/12 13:41:45 When are we getting phong shading?! WHEN?!  Fifth  #245 posted by mankrip on 2015/12/12 13:57:46 If EricW doesn't implement it, I will. But a proper implementation will most likely require surface flags (or, more specifically, surface groups), and the actual algorithm may not be Phong shading, but something that looks similar. There are a number of design issues to consider. This is one of the features that I've been thinking about during this whole year, and it's not simple.    #246 posted by adib on 2015/12/12 14:32:09 And when are we having radiosity? Oh Lord, when? I wonder...  Well  #247 posted by FifthElephant on 2015/12/12 14:38:48 for organic geometry how about something like "func_detail2" or "func_group2"? Something outside the regular thing that just applies it to a whole brush?    #248 posted by FifthElephant on 2015/12/12 14:39:34 I know it would be more ideal to apply it to surfaces but I would love to see something, *ANYTHING*, in the mean-time.  #247  #249 posted by Kinn on 2015/12/12 14:46:58 better to have a key:val on any func entity e.g. _smoothangle: 15 That way you can control which faces get smoothed based on angle.    #250 posted by FifthElephant on 2015/12/12 14:51:07 I would be all in favour of Quake 2 style surface flags... I know it's introducing a new format for Q1 but at this point does it matter?    #251 posted by Kinn on 2015/12/12 15:01:13 I would be all in favour of Quake 2 style surface flags... I know it's introducing a new format for Q1 but at this point does it matter? You have to think about compatibility with editors like netradiant that are no longer being updated.  #247  #252 posted by mankrip on 2015/12/12 15:26:00 This would create yet another legacy feature that would become redundant and require extra work to avoid conflicts and retain compatibility with. Plus, most of the work I need to do before developing my approach is to implement a bunch of BSP debugging features in the engine, in order to analyze and tweak things properly without blind trial and error. The smoothing algorithm itself shouldn't require much time afterwards.  Adib  #253 posted by Spirit on 2015/12/12 15:54:43 q1rad    #254 posted by JneeraZ on 2015/12/12 16:13:27 What's the deal with q1rad?

The problem is that the final results can be quite washed out and lack contrast. I lit crdm2 with it and looking back now, oh god the lighting is awfully dull!  Yeah  #256 posted by Lunaran on 2015/12/12 20:33:28 the q2 light tool supported radiosity too. default 8 bounces, max 40. in retrospect, the best looking option would have probably been -bounce 1, which is what I'd use for quake if we had it (one pass of scatter and that's it). since Q2 came out when I was young and dumb I thought -bounce was one of those parameters that you set to the maximum when you do your 'final compile' so I basically released two needlessly washed out yellow Q2 maps. vrad for source just does the max number of bounces it can, and when it runs out of light it stops, but their scatter and falloff equations were probably adapted out of a real optical physics textbook by an in-house mathematician they pay a half million dollar salary, so it always looks perfectly real in HDR.  Smoothed Lighting  #257 posted by Spike on 2015/12/12 21:34:55 http://triptohell.info/moodles/junk/tyr_smoothnstuff.zip adds a _smooth key to your func_detail entities that smooths the normals across surfaces. you might want to use -anglescale 1 or the equivelent field in order to prevent quake's harsh boundaries between lit and unlit areas. the qbsp flags the various surfaces. it doesn't currently support smoothing groups, but it would be the qbsp that would need to generate dupe verts for surfaces with different groups (this ensures that engines with specular effects can work correctly). also adds a few other things that I've been messing around with. check the readme (be warned that much of the extra stuff only works with fte, but not always to the detriment of other engines - _lmscale has a well-defined fallback). there's probably other issues with it - I'm not the intended audience so I'm kinda lazy where it comes to testing. per-surface flags would be really nice right now... but yeah, map editors.  Cool, Thanks Spike!  #258 posted by ericw on 2015/12/12 21:44:45 Will check it out in a bit  Spike  #259 posted by FifthElephant on 2015/12/12 21:49:14 not sure how it works.. I made a key in my func_detail as _smooth and put the texture name in the field but it doesn't do anything?  High Five, Spike  #260 posted by mankrip on 2015/12/12 21:49:24 I'll take a look at it too.  Screenshot  #261 posted by FifthElephant on 2015/12/12 22:05:14 I'm trying to make the big pipe in the middle lit smooth... even with this util I am not getting smoothing. http://www.quaketastic.com/files/screen_shots/5thnophong.png Any ideas?  Fifth  #262 posted by ericw on 2015/12/12 22:58:09 It's working for me: http://imgur.com/a/8KLPX That's with just one light entity, "_anglesense 1" set, delay 3. What kind of light sources are lighting the pipe currently? If it's _sunlight, try adding "-anglesense 1" to the light command line, this controls how much sunlight (only regular sunlight, not _sunlight2) is affected by normals, 1 is the maximum amount. Sunlight2 ignores normals, so try turning it off if you're using it. You're running both spike's qbsp + light?  Eric  #263 posted by FifthElephant on 2015/12/12 23:06:06 I just tried it on an indoor area and it seems to work. It's not quite as good as the smoothing in Quake2's tools. I get very weird lighting on pipes for example (it's smooth but it doesn't like pipe bends and I'm getting harsh results)  Cool  #264 posted by ericw on 2015/12/12 23:21:15 i'd imagine with some polishing it can be made to work as well as Q2's, the Q2 tool source is available too.  Per Surface Flags  #265 posted by mh on 2015/12/12 23:23:11 I haven't given this a whole load of thought, but just wondering how much of a big deal it would be to just use the Q2 .map format but compile it to a Q1 .bsp format.  Ok  #266 posted by FifthElephant on 2015/12/12 23:23:21 I managed to come up with a solution that works... I've made just the visible faces have the texture that needs to be smoothed. This seems to only work with indoor lighting though. I do hope it can be applied to outdoor lighting too since I don't want to go back to the horrible method of lighting prior to sunlights. Here's an example that shows the difference between phong shading and normal quake lighting - https://twitter.com/GavinEdgington/status/675802921334915072  Specifically  #267 posted by FifthElephant on 2015/12/12 23:27:24 The pipes have lighting issues if anything but the visible faces have the smooth texture. I made the non-visible connecting faces use a skip texture to avoid these errors.    #268 posted by ericw on 2015/12/12 23:33:40 Ah, I see what you mean Fifth, sunlight is not phong-shaded. I'll see if I can fix it.  Good!  #269 posted by mankrip on 2015/12/12 23:52:54 It's not perfect, but it's a lot better than the standard lighting. Another bonus point is that now I can wait some more time before developing my own approach. There are lots of things to do�  #265  #270 posted by mankrip on 2015/12/13 00:02:46 Editor support could get messy. It would probably require messing around with FGD files to convert Quake entities to Q2 entities� or convert the Quake FGD to the Q2 specs. I know about the differences between Q1 and Q2 BSPs, but never thought about looking into the differences between their .map formats.  Implementation  #271 posted by FifthElephant on 2015/12/13 00:03:03 is certainly not perfect and I would want to be able to have _smooth work with other brush types like func_group etc.  I'm Sorry For My Sins!  #272 posted by Spike on 2015/12/13 03:44:59 @mankrip afaik .map format doesn't have that many differences, just 3 extra args. brush contents, face flags, and face light level. tyrlight already parses q2 maps and generates q1 bsps, however it completely discards the extra 3 args (also, no value texture alignment tweaks). I don't see why you'd need q2 fgd changes at all, you'd still be targetting q1 mods and tools, and editors that support both would likely continue to support both without really caring. the real issue is 1) editors that do not support quake2. 2) editors that insist on using wal files instead of wads. 3) editors that assume the palette is that of quake2 instead of quake. for the editors that are mainitained tbh all it requires is for someone to be vocal enough - its amazing how much of a motivator harasment can be. @ericw I didn't change anything to do with sunlight that I remember, so yeah, no support there. sorry about any other issues with it too. I was going to sit on it while someone else found the kinks for me, before making it public. but, well, open source matra: release early, release often. I'm too lazy for the second part though. by releasing I hoped to at least save some time for mankrip. in theory it should be possible to switch the barrycentric coords part to use the entire polygon instead of a triangle (giving a less-triangular/higher-quality apearance), but I just went with what I understand. @Fifth, there's nothing specific about classnames, it ought to work with any classname (at parse-time, on account of the way it flags texinfos). certainly there's nothing specific to func_detail. all I can really suggest is to make sure that there's no tiny cracks between faces, because it calculates normals at each vertex and then just interpolates those over the various triangles that form the surface in a similar way to how a gl engine would interpolate normals. remember that it'll happily smooth around any angle, 20 degrees, 90 degrees, 170... this means you'll likely want to use some other texture for the top/bottom of your mid-pipe cylinders so that they don't cause it to try to curve around those rings. secondly, sunlight isn't supported right now. if you're looking at the map in fte or dp, make sure you disable any specular first. the texinfos are flagged to say that normals should be interpolated, but engines don't understand that yet, and yeah, I forgot sunlight, and there can still be harsh (often mid-surface) boundaries due to the maths behind the anglescale thing (at one point I was toying with the idea of these surfaces just always using a value of 1).  Update  #273 posted by ericw on 2015/12/13 05:22:37 I fixed a few bugs that were causing black fringes in my phong test map, and added support for phong+sunlight. Here is a build: http://quakespasm.ericwa.com/job/tyrutils-ericw-spike/3/artifact/dist/tyrutils-ericw-v0.15.3-7-g05de1ad-win32.zip and the source code: https://github.com/ericwa/tyrutils-ericw/commits/smoothnstuff Hopefully this works on your map, Fifth! Note, this is based on the previous release of tyrutils-ericw (0.15.3), I'll need to do some merging later on.  Editor Support  #274 posted by SleepwalkR on 2015/12/13 07:54:33 I'd add support for Quake 2 map in Quake games in a jiffy. Would be really easy too.  Eric  #275 posted by FifthElephant on 2015/12/13 10:07:32 That seems to work actually. Very cool. Have you altered the code at all? It seems slightly less smooth than before (but still a lot better than ordinary lighting).    #276 posted by FifthElephant on 2015/12/13 12:19:19 Seems like whole number integers on vertices or on texture alignment place a huge role in getting the lightmap to look right. Otherwise you get huge black bars or just errors in the lightmap.  Fifth  #277 posted by ericw on 2015/12/13 20:15:37 I see what you mean about less smooth / more banding, I messed up something with that last build; trying to fix it..    #278 posted by ericw on 2015/12/14 00:13:48 @Fifth here's another build to try, I think it fixes the things I broke in the last one: http://quakespasm.ericwa.com/job/tyrutils-ericw-spike/9/artifact/dist/tyrutils-ericw-v0.15.3-10-g896b821-win32.zip There is still room for improvement; I still get a few fringe artifacts on some terrain that was rotated 15 degrees, but it's pretty minor and way better than the last build. @Spike: I switched this build to use SSE; for some reason x87 vs SSE was making a difference in the barycentric coordinates code, with SSE having less artifacts when interpolating points outside the triangles. I will investigate it better at some point :-)    #279 posted by FifthElephant on 2015/12/14 08:31:59 I will give it a whirl after work. These compilers give me leaks compared to the ones I normally use    #280 posted by FifthElephant on 2015/12/14 08:32:52 I normally use bjp's compilers.    #281 posted by ericw on 2015/12/14 19:03:59 Yeah, these are less forgiving than bjp's. Raising the -epsilon parameter to qbsp can help, default is -epsilon 0.0001, try 0.001, 0.01  Light.exe  #282 posted by FifthElephant on 2015/12/14 22:27:05 seems to crash for me in this build. No idea what's causing it.  Shit, Sorry  #283 posted by ericw on 2015/12/14 23:18:44 Here's another try... http://quakespasm.ericwa.com/job/tyrutils-ericw-spike/10/artifact/dist/tyrutils-ericw-v0.15.3-11-g78ca193-win32.zip I notice extra/extra4 + soft crashes this one. Sorry about all the buggy builds but it'll take a bit to get all of this stuff stabilized and merged. I gotta go map first!  Hmm  #284 posted by FifthElephant on 2015/12/15 01:06:24 This one appears to compile but I'm getting some black bars across surfaces even worse than the first build. It's very likely this is due what I am testing it on (bsp pipe work) and is caused by micro-leaks and things along those lines. I suspect there might not be an easy fix for this other than to reduce detail for smoothed light maps, have smoothed textures use whole number values instead of decimals when doing its calculations? (I'm pretending I know what I'm talking about by this point, from my tests it appears that the closer to a whole number you get the better the smoothing appears to be across a surface).  #284  #285 posted by mankrip on 2015/12/15 02:35:37 In some cases, the position where two vertices of two different brushes meet can become different for either brush due to differences in precision between them during the compiling. This will make the hidden orthogonal face of one of them to pop out, and this will mess up with the smoothing algorithm indeed. It's one of the extreme cases I had predicted, but it shouldn't happen too often.  QBSP Error  #286 posted by - on 2015/12/16 12:45:59 ERROR: Too many vertices ( 65541 > 65535 ) Map also leaks in some mysterious way I haven't deduced yet because there is no .bsp generated due to the error... not sure if they are related...

Any reason why this limit couldn't be raised?  Oh  #287 posted by - on 2015/12/16 12:49:16 nm found the leak, and is what causes the vertex overflow...    #288 posted by ericw on 2015/12/16 19:54:15 Cool - if you need >65k verts, I think you just have to switch to bsp2 with the -bsp2 flag. I will add that to the error message.    #289 posted by JneeraZ on 2015/12/16 20:05:33 Which is actually a good working philosophy even if you don't want to ship a BSP2. It allows you to work on an unsealed map for much longer.  But  #290 posted by ijed on 2015/12/16 20:28:09 Bad working practice IMO. The longer you leave something unsealed the bigger the final task of sealing it. I prefer keeping everything sealed as I go along, even if it's with giant bricks I'll eventually delete. At least then I know that everything else is without b0rken3ss.    #291 posted by - on 2015/12/16 21:46:21 Well, this only leaked because I'm working on this map with Lun and I merged in some of his stuff, and one of the brushes was apparently corrupt after import. Think even with some more to do, we'll still be well under and won't need to bsp2.    #292 posted by JneeraZ on 2015/12/16 21:46:34 Depends on the map. I've had times when it would have been a fuckton of work to seal the map and it just wasn't time ...    #293 posted by anonymous user on 2015/12/16 22:44:05 The longer you leave something unsealed the bigger the final task of sealing it.   ^^that Needs To Be Framed  #294 posted by mfx on 2015/12/16 22:45:08 and whatnot.  Hey EricW  #295 posted by mankrip on 2016/01/04 23:04:08 I've confirmed that the problem with not all water surfaces being lit is a tools bug. The light tool will only generate lightmaps for the liquid surfaces that gets hit by a light entity's beam. If no beams hit a liquid surface, no lightmaps will be generated for it. I couldn't figure out a simple way to fix this yet. I'm compiling the maps with qbsp -splitspecial enabled.  Mankrip  #296 posted by ericw on 2016/01/05 00:17:23 I see, normally face->lightofs == -1 means the lightmap is black, but for liquids you need to treat -1 as "not compiled with lightmapped water, so render fullbright", is that right? It should be easy enough to always save lightmaps for liquid faces, even if solid black. But I don't think I added lightmapped liquids support to tyrutils-ericw, do you have the code for it already? I am happy to add a command line flag for it, just don't want to waste time reimplementing it if you already coded it.    #297 posted by Spike on 2016/01/05 00:41:24 that would be my fault. I added -lightwater etc args in that smoothnstuff branch, but didn't actually get around to testing it at all. (release early, release often, right?) it should be simple enough to tweak WriteLightmaps to just write a lightofs of 0 instead of -1 when texinfo->flags&TEX_SPECIAL, with all styles still set to 255, I guess. I assume engines will be able to cope with that, but I've not checked.    #298 posted by FifthElephant on 2016/01/05 00:46:09 Wasn't there a concern due to the way that most engines render water by using a deforming mesh?    #299 posted by ericw on 2016/01/05 01:07:48 @Spike ah, cool. Still meaning to merge in your smoothnstuff branch, just lazy right now :) @Fifth hm good point, this will need to be tested. Also thanks for the idea about using "smooth" prefix on texture names to enable phong shading, that could be good.    #300 posted by Spike on 2016/01/05 02:11:08 re: unmerged branch I wouldn't worry too much, I've been too lazy to fix any niggles since I uploaded it. :s re: smooth prefix I disagree in the long term on account of that making multiple smoothing groups too awkward to use effectively. supporting q2 .map files for their surface flags would be good. tyr's qbsp can already parse them, so we just need editors that support q2 .map with wad files, and to actually implement smoothing groups with it. re: lit water yes, lit water would generally imply that the lit water surfaces should also be subdivided by the qbsp in the same way that regular walls are (this means the qbsp needs to be aware of it too, and not just the light tool). engine-based turb subdivision isn't really a concern, as it doesn't affect the lightmap. there are already occasions where surfaces are overly pointy. if anything, having the qbsp subdivide turb surfaces too would reduce this the 'real' concern is that very few engines actually support lit turb surfaces re: nstuff I kinda want to build func_illusionaries and brushes with alpha-masked textures into the world too. conceptually this would be easy (assuming it doesn't have any fields set), they can just be treated like some water contents with water vising stuff, and be converted to the appropriate contents type just before qbsp outputs the unvised bsp. this should improve engine batching and stuff (and be consistent with what hlbsp support already requires from engines). there's some other things that need tweeking, but I forgot much of it. :s    #301 posted by mankrip on 2016/01/05 02:28:40 Yes, I've fixed something else in the light tool for the lights to display properly on liquids, but by default you just need to compile the BSP with qbsp -splitspecial. This will make water surfaces be subdivided, and with the TEX_SPECIAL flag not set. In theory, this should have made them be treated exactly like regular surfaces by the light compiler, so this bug with fully dark liquids is puzzling me�  Here's The Code  #302 posted by mankrip on 2016/01/09 18:49:42 I've managed to fix it tonight. It should be bug-free, but it would be better to attribute a dummy lightstyle for fully dark liquids, to avoid potential "too many light styles on face" warnings.

There's a section of the light manual "Model Entity Keys" but it's easy to miss!  Yay!  #307 posted by PuLSaR on 2016/02/04 20:43:05 That crash is really fixed in 0.15.4. And thanks for pointing me at _minlight key, I really managed to miss it.  Some Ideas  #308 posted by PuLSaR on 2016/02/05 16:36:38 Is it possible to make something similar to the shadow brush in hl2? It's a brush covered with texture with a special name (like skip) and doesn't have collision but casts shadows like it was a visible brush. That would allow to manually create shadows for models (AD trees come to mind) or some new lighting effects. If something like this already exists in quake you can point me at it.  Skip Texture + Func_illusionary?  #309 posted by ijed on 2016/02/05 16:55:44   I Supposed Skip Textured Brushes Don't Cast Shadows  #310 posted by PuLSaR on 2016/02/05 17:08:03   Pulsar  #311 posted by mfx on 2016/02/05 17:58:05 Set _shadow 1, or is it _shadows 1?    #312 posted by FifthElephant on 2016/02/05 18:08:04 What mfx said  Are The DP Lighting Errors  #313 posted by dumptruck_ds on 2016/02/05 19:39:43 you patched still in these new versions or was that a separate branch you gave me?  Tree Shadows  #314 posted by necros on 2016/02/05 19:49:34 maybe a func_wall which is kill targeted immediately with a fence texture of leaf shadows????    #315 posted by Baker on 2016/02/05 19:52:56 (I thought about posting that necros, but that's cheesy.)    #316 posted by ericw on 2016/02/05 20:07:25 dumptruck_ds: Yeah, the fixes for DP are in the main branch v0.15.4 which is what I recommend using: http://ericwa.github.io/tyrutils-ericw/ I think Spike has a better fix for the problem in qbsp in his patch, I want to test it a bit; I hope to return to working on this soon and merge his stuff and mankrip's patch :-)  Mdl Shadows  #317 posted by ericw on 2016/02/05 20:16:54 It would be possible to make the light raytracer trace through mdl's so they cast proper shadows. If an entity has "_shadow" "1" set and "mdl" or "model", try to load that mdl? there would need to be -basedir / -game flags to light so it can find your mdl's. The thing that would mess it up, though, is this would likely make the mdl's black in game, since they would usually cast a shadow over where the engine samples the lightmap. So it might not be worth the effort  Fun Ideas Mostly For Entertainment Purposes  #318 posted by Baker on 2016/02/05 21:11:35 More or less as amusement ideas. 1) WAD3 support. Screeshot More fun with more colors. Sample halflife.bsp download which Mark V can load both in the Open GL renderer (and also in the software renderer too!) Adding Half-Life map BSP 30 type of support is rather easy in the engine. 2) Rotation. You thought about it last summer. 3) Mirrors visibility support. /Like people haven't posted enough ideas in this thread!  Ok Check This Out For A Wishlist  #319 posted by Kinn on 2016/02/05 21:22:27 Following on from what ericw said about shadows from mdls, there's a problem obviously in how the engine lights the mdls in game. Imagine also lighting the models properly - i.e. the light tool writes a new type of lit file that saves lightmap information for specifically flagged mdl entities - then custom engines can read these new lightmaps and if one exists for a model it uses that rather than using the default way of mdl lighting...  WAD30 Is HL1?  #320 posted by onetruepurple on 2016/02/05 21:24:55 What's the benefit, considering how modern engines already allow 24-bit external textures?  Ericw, Spike & Mankrip  #321 posted by dumptruck_ds on 2016/02/05 21:34:27 You guys rock thank you for the DP fixes.

On the ground, under the shadow is a rocket launcher --- also a .mdl. Should the rocket launcher get a shadow from the object above? Or not receive a shadow because it is a .mdl. Or worse, a player types r_shadows 1 in the console --- now what should happen? Then, out of nowhere, Barnak shows up and fires a rocket, generating a dynamic light to add to the mix ... Not only that: a decent chunk of people use DarkPlaces and it not really known whether or not DarkPlaces may ever be updated again by LordHavoc who is off doing prosperous things. I think many of those users griped quite a bit about alpha textures in the Arcane Dimensions release, in large part because AD was an exceptionally high profile release. (Complex world ...)  EricW  #323 posted by mankrip on 2016/02/06 00:28:51 I've noticed that lit water gets dirtmapped, but it doesn't generates dirtmaps on the other surfaces. Generating dirtmaps on the other surfaces could be a cheap alternative to alphablended shorelines. But maybe some mappers would prefer to just not generate dirtmaps on liquid surfaces at all. Also, my code doesn't take care of sunlights. Please take a look to see if sunlights should also be modified for backfaced liquid surfaces.  Hacky Suggestion  #324 posted by Preach on 2016/02/06 18:05:05 Is it possible to make something similar to the shadow brush in hl2? It's a brush covered with texture with a special name (like skip) and doesn't have collision but casts shadows like it was a visible brush. Yes, it's called info_null : - p Seriously, a brush-based entity with info_null and "_shadow" "1" should case shadows but disappears in-game. It does use up a model precache, but you should be able to safely combine all of them in your map into one entity to it only takes a single slot away.    #325 posted by necros on 2016/02/07 17:32:34 oh heh, that's a good idea. i was thinking of making think: SUB_Remove and nextthink:1.0 or something but that's even better.  Default Quake With Dirt AO  #326 posted by Skiffy on 2016/02/08 14:06:19 I thought I would find it in here but does anyone remember the batch tool for recompiling all of quake1's maps to use the new dirt AO?  I Wouldn't Recommend Doing That  #327 posted by mankrip on 2016/02/08 14:33:53 Vanilla Quake has several places, like the wooden stairs to the E4 pool in the start map, that doesn't behave well with dirtmapping.

Nice to know that works! :)  Light Styles  #334 posted by necros on 2016/02/14 05:06:48 Is something changed with the way 'style' is done on lights? I have a bunch of lights in my map with no targetname, but I have manually set them to use style 12. I then was changing them in QC by directly referencing style 12 instead of doing the typical target/targetname shtick. However, this no longer works with the new tyrutils (I was using aguirre's light before). I've checked my code and I'm still modifying style 12, but it seems like the lightmaps lost their styles..?  Necros  #335 posted by ericw on 2016/02/14 06:37:30 weird, that should work. If it was broken in the tool, I'd expect the regular flicker styles 1-11 would also be broken. Try version 0.15.4 from http://ericwa.github.io/tyrutils-ericw/ if you're on a different version?  Ohh Ok  #336 posted by necros on 2016/02/15 02:53:13 i see, for some reason, delay 4 lights cannot have lightstyles in tyrutils? can we revert that so that it works with all lightstyles? also, it appears that delay 4, 'local minlight' is broken? it looks just like a normal light.    #337 posted by ericw on 2016/02/15 04:12:38 Ah, good catch, delay 4 lights don't support lightstyles. They are handled in a different function that applies minlight, and it just assumes the style is 0. Should be easy to fix. As a workaround, delay 3 (infinite) should be almost the same as delay 4, especially on styled lights, because the engine will be blending the base lightmap with the styled one, so you wouldn't really get a minlight effect even if the styled light was using delay 4. Delay 4 is working correctly for me otherwise, though. Maybe send over the map if you can't get it going?    #338 posted by necros on 2016/02/15 04:38:04 nm about the delay 4 not working. i think it was the dirt mapping making it look like it was attenuating. :P  Brush With Duplicate Plane  #339 posted by DeeDoubleU on 2016/02/15 09:59:47 Trying to find problematic brush atm. Log blames line 66597. Using notepad++ to edit .map file (manually cut bunch of entities and see if problem is gone) and through described process I found that compiler and notepad probably count lines differently, because given line was commented one (entity number) few times or part of a light entity.

Fifth has a build with it that is working, and I hope to post a new dev build soon that has phong shading too. DeeDoubleU: weird, I don't use notepad++ but it should have a "goto line" feature that should take you to the right line. Anyway, I don't think "Brush With Duplicate Plane" is a serious warning, it's more a warning that the editor saved some redundant data.    #352 posted by PuLSaR on 2016/02/15 21:16:44 this document never gets old.    #353 posted by Skiffy on 2016/02/16 01:57:40 Lit water yeeeesss I look forward to that one because my level has murky water like a swamp / bog and I would love it to be dark shader fluids.  Swamp/bog  #354 posted by mfx on 2016/02/16 02:00:59 /triggered  Quake2 Plans?  #355 posted by Skiffy on 2016/02/16 06:35:48 Any plans to ever include radiosity in the light compiler for Tyr like in Quake2's Light compiler? Regarding Quake 2... possible support for it using these compilers at some point in the future? I read it does support the map format but does it output quake2.bsp files? Currently I think ArghRad is the lighting one for quake2 maps correct and no other tools came after that outdid it? I would love the AO / Dirt / Skylight / Sunlight from Tyr tools to be usable for Quake2. The main things Q2 still had is Smooth Shading and Radiosity though.. Just wondering because I love this toolset and some offshoot in the future would be great.  Radiosity  #356 posted by mh on 2016/02/16 17:33:02 It's actually important to understand that there are not one but two major differences to the Quake 1 lighting model in Q2. When people say "radiosity" it pays to be clear about which of these two is actually meant. First one is actual "radiosity", as in the ability of surfaces to cast light. Second one is bounced/indirect lighting. Thing is, these two don't actually have any dependency on each other. It's possible to implement each without implementing the other. So you can have surfaces casting light but without light bounces - similar to what these tools already do with lava surfaces. And you can have indirect lighting but have it coming from light entities which the mapper must place rather than from surfaces. Or you can have both; but presence of one doesn't demand presence of the other.    #357 posted by necros on 2016/02/16 21:48:22 Dirt/AO makes radiosity a bit redundant at this point. It's also slower.    #358 posted by Kinn on 2016/02/16 21:57:29 Also, Quake 2's radiosity actually created a result the same as if you'd just floodfilled the lightmaps with the same flat shade of orange/brown.    #359 posted by Kinn on 2016/02/16 21:58:46 That said, a single bounce could be interesting. I'm sick of adding fake bounce lights.    #360 posted by necros on 2016/02/17 00:58:17 Yeah,maybe I shouldn't dismiss it out of hand. and with multicore lighting, it's maybe not so bad anymore.    #361 posted by onetruepurple on 2016/02/17 01:13:53 That is not dead which can eternal compile. And with multicore lighting, even death may die.    #362 posted by Skiffy on 2016/02/17 02:12:19 Light bounce is indeed what I am looking for. Light bounce that picks up the colors from the surfaces it hit is one thing I liked a lot from Q2 lighting. And we all know the Orange lighting was just them having too much fun with colored lights as it was relatively new technology in games and folks sucked at using color for lighting their levels. And no Radiosity is not redundant because we have dirt / AO... that is a hack of light occlusion not the spread of lighting. But yes Radiosity is an old way of doing GI. There are better ways to do it these days which are also much faster. Ultimately I would love to see this toolset support quake 2 and include the smooth shading and Radiosity features from Arghrad.    #363 posted by ericw on 2016/02/17 04:05:55 Skiffy, yeah I'd like to implement some kind of bounced lighting, like this article: http://www.scratchapixel.com/lessons/3d-basic-rendering/global-illumination-path-tracing Probably just supporting 1 bounce to start with. It actually looks very similar to how dirtmapping works currently. I'm not sure how hard it'd be to add Q2BSP output. Spike might know? Also, I should have a new beta soon.    #364 posted by Spike on 2016/02/17 05:50:38 q2 renders much like q1bsp. its the tracelines that are very different. that said, I think you can still use the q2 bsp tree as a point-sized hull, so that's fine for light. this is of course ignoring all the changed structs that you'd have to deal with somehow (easiest to do at compile time).    #365 posted by Skiffy on 2016/02/17 06:51:27 Sweetness! 1 bounce would already be a great start.    #366 posted by Rick on 2016/02/17 08:52:27 One or two bounces would be fantastic. It could save a lot of trouble. As it is now, for indoor areas I probably place 3 to 5 fills for every actual light.    #367 posted by necros on 2016/02/17 12:36:15 1 bounce with light diffusion would be cool.    #368 posted by mh on 2016/02/17 12:43:12 Personally I'd suggest adding a "_bounce" key to light entities; default if there's no key is no bounces (makes sense to keep defaults same as stock Q1 tools) and the value specifies the number of bounces. That way lighting could be easily recreated at any time and by other tools without needing to know the command-line options that were originally used.  Ericw  #369 posted by DeeDoubleU on 2016/02/17 13:46:39 weird, I don't use notepad++ but it should have a "goto line" feature that should take you to the right line. Anyway, I don't think "Brush With Duplicate Plane" is a serious warning, it's more a warning that the editor saved some redundant data. It's not that I can't find exact line which correspond to log output - notepad++ shows line numbers. Problem is compiler treats line numbering differently. I think I found the problem - it doesn't count comment lines. Tested on my map backup. Compiled as is *** WARNING 03: line 45402... added a bunch of commented out lines("//asdasd") , in the beginning of the file and line number didn't change in the log. Then I replaced commented lines with empty lines, just a line break. No spaces, tabs etc Now log says *** WARNING 03: line 45406... If it is the case, then every line with entity/brush number gets ignored and line numbers 'shift' from what you would get in text editor.  Don't Let Your Dreams Be Dreams  #370 posted by khreathor on 2016/02/17 14:25:26 Sorry for little OT. There is nice BSP importer for Blender. I would love to bake static Lightmap there and export it back to BSP. In overall some lightmap import option would be great. I know it's hard, because BSP is just fragmented mesh "dump" and lightmap is low res, but we can think about some solution.  Khreathor  #371 posted by mankrip on 2016/02/17 18:29:24 You could create external LIT files � but that requires writing an exporter plug-in for Blender.  LIT Files  #372 posted by khreathor on 2016/02/17 18:40:48 hmmm.... any link to proper LIT documentation?  External Lighting And Settings  #373 posted by Skiffy on 2016/02/18 04:46:40 Hmm being able to read and write the lighting from and to BSP would be a rather fantastic addition but then you run into a world of pain if you want more light styles supported. how to handle flicker lights and so forth because those get layered on top and limited to the polygons they affect if I remember correctly. As for the _bounce you could do that or just add it to the compiler as a global option. Same goes with bounce multiplier and saturation. How much energy is maintained when it bounces and how much color is picked up when it hits the surface. In Unreal you can tweak these values so its more saturated and propagates lighting further by not losing as much energy on the first bounce.    #374 posted by khreathor on 2016/02/18 14:06:03 yeah, I know about light styles being problematic in this situation. I'm going through source to fully understand how it works.  Global  #375 posted by adib on 2016/02/21 20:41:09 As for the _bounce you could do that or just add it to the compiler as a global option. Then make it a worldspawn key, so that way lighting could be easily recreated at any time and by other tools without needing to know the command-line options that were originally used.   Skiffy  #376 posted by DaZ on 2016/02/21 23:46:04 There is a port of the half-life 1 radiosity lighting tool to quake 1 you could look at?

Thank you all for the efforts, really...can't be said enough.  Fifth  #383 posted by ericw on 2016/04/15 22:38:48 btw, the key for phong shading has changed since the version you were using, you no longer need to give the texture name. The main improvement of this new version is having an angle cutoff, so it won't smooth around 90 degree corners by default (the cutoff is 89 degrees.) Another new feature: when using phong shading I suggest setting "_anglesense" "1" in worldspawn, this affects all lights in the map that don't override "_anglesense". This will make phong shading more visible and generally increase contrast.. it makes the angle that light arrives on a surface matter more than the quake default.    #384 posted by FifthElephant on 2016/04/15 23:23:26 I'm not sure I will change compilers unless I am really compelled to  No Worries  #385 posted by ericw on 2016/04/15 23:49:13     #386 posted by FifthElephant on 2016/04/16 00:45:23 Does it apply phong shading to the whole brush?

I think there should be a way to choose to either have the model phong shaded or certain textures.    #393 posted by Kinn on 2016/04/16 13:29:19 Dunno, I think with the angle cutoff and the fact that you can break it down into as many func_groups or func_details as you want, the current system seems pretty ok? I'm just trying to envisage a scenario where that's not enough, and I'm struggling....    #394 posted by FifthElephant on 2016/04/16 14:05:25 complex func_groups like this - https://twitter.com/GavinEdgington/status/714465169649377281 Where I don't want to have to break up into small groups because it will make it a pain to move around and place.    #395 posted by ericw on 2016/04/16 20:13:21 The angle cutoff is pretty flexible, if you set it to a low value like 30, only pairs of faces with normals up to 30 degrees apart will be smoothed together. So I imagine something in 30-60 would work well on that spaceship, and not add smoothing in unwanted places. Also it's easy to check what the phong shading is doing, just compile with the light flag -phongdebug. I could add back the list of textures to restrict phong shading to, if it's really needed, though.    #396 posted by Lunaran on 2016/04/16 20:20:26 You guys are fighting the engine's weaknesses instead of playing to its strengths.

This means lit water should "just work" without changes to light - so the -transwater stuff Spike added is unnecessary. Your patch just makes the bottom face receive light from above, rather than underwater, right? That seems sensible since typically most of the light sources will be above the water, but not having that shouldn't cause the artifacts in your first screenshot.    #411 posted by Spike on 2016/04/17 05:56:19 all I can say is that the water parts of my patch were completely untested, and only half written. yeah, I got bored and then forgot about it, okay? please forgive my sins! so that I can more easily commit them in future! mwahaha! the bright part of the water is probably a poly with no lightmap info at all (which technically means all-white-but-not-overbright instead of all-black when found on water surfaces). this would imply that much of that area is normally lit from below. I don't think it tries to subdivide water either. I guess this means that the controls for whether water should be lit should really be inside the qbsp instead.    #412 posted by mankrip on 2016/04/17 06:04:40 Your patch just makes the bottom face receive light from above, rather than underwater, right? It makes each face receive light from both under and over the water, to match the lighting on the nearby walls. The normal inversion is done on a per light entity basis - the face's normals will only be inverted for light entities behind it. now I realize that -splitspecial means water won't have TEX_SPECIAL set. This means lit water should "just work" without changes to light -splitspecial also splits the water surfaces into the appropriate size for lightmap creation. typically most of the light sources will be above the water, but not having that shouldn't cause the artifacts in your first screenshot. As mentioned at InsideQC, my code includes a hack to force liquid surfaces' lightmaps to always be saved, otherwise fully dark liquids would remain fullbright.  BTW  #413 posted by mankrip on 2016/04/17 06:14:07 It would be better if the -splitspecial option in the qbsp was replaced with -splitturb and -splitsky options. There's no need to split sky surfaces, because there's no need to make them receive regular lighting.    #414 posted by ericw on 2016/04/17 06:33:40 It makes each face receive light from both under and over the water, to match the lighting on the nearby walls. The normal inversion is done on a per light entity basis - the face's normals will only be inverted for light entities behind it. Ok, cool, I'll try merging this in. As mentioned at InsideQC, my code includes a hack to force liquid surfaces' lightmaps to always be saved, otherwise fully dark liquids would remain fullbright. I think this bit is missing from your patch? This does seem like a hack around an engine bug... There shouldn't be any ambiguity; in an engine supporting lit water, a face with face->styles = 255, face->lightofs = -1, TEX_SPECIAL unset, and texture name starting with '*' should be rendered black, right?    #415 posted by mankrip on 2016/04/17 07:35:30 This does seem like a hack around an engine bug... There shouldn't be any ambiguity; in an engine supporting lit water, a face with face->styles = 255, face->lightofs = -1, TEX_SPECIAL unset, and texture name starting with '*' should be rendered black, right? It's not an engine bug, the lightmap data is missing from the BSP file itself. For some reason, if no lights touches a liquid surface, no lightmap data is generated for it. I've studied the light.exe code for hours and couldn't figure out what causes this, so I've just forced the lightmap data of liquid surfaces to always be generated. With no lightmap data, the surface cache for the lighting can't be created. I think this bit is missing from your patch? It's not missing, I've just implemented it in a subtle way: /* don't bother with light too far away */ if (dist > entity->fadedist) if (!backwater) // mankrip return; This allows far away lights to be casted on liquid surfaces, therefore forcing the lightmap data to be generated - even though far away lights won't add any brightness to it.    #416 posted by ericw on 2016/04/17 08:06:35 It's not missing, I've just implemented it in a subtle way Ah, I see :) It's not an engine bug, the lightmap data is missing from the BSP file itself. For some reason, if no lights touches a liquid surface, no lightmap data is generated for it This is not specific to lit water.. light.exe will not write fully black lightmaps to the bsp. It was a compression / optimization in the original light tool and engine; lightofs of -1 is rendered black. You can see this by deleting all lights except a small dim one in a large map, the lightdatasize will be only be a few hundred bytes. here's the early exit in light: (f->lightofs = -1; is set earlier) https://github.com/id-Software/Quake-Tools/blob/master/qutils/LIGHT/LTFACE.C#L542 and places where it is handled in the engine: sets surf->samples to NULL if face->lightofs is -1: https://github.com/id-Software/Quake/blob/bf4ac424ce754894ac8f1dae6a3981954bc9852d/WinQuake/gl_model.c#L795    #417 posted by mankrip on 2016/04/17 08:37:18 This is not specific to lit water.. light.exe will not write fully black lightmaps to the bsp. I know this. I don't remember all the details on why the lighting for liquids couldn't be generated if the light data wasn't present in the BSP file, but I will take a look at it again later.    #418 posted by mankrip on 2016/04/17 16:41:55 Alright, I've had some sleep. Here's the proof why the lightdata for liquid surfaces must always be generated. In Mod_LoadFaces: if (!Q_strncmp(out->texinfo->texture->name,"*",1)) // turbulent { out->flags |= (SURF_DRAWTURB | SURF_DRAWTILED); The SURF_DRAWTILED flag in the engine is similar to the TEX_SPECIAL flag in the tools: it serves to indicate that the surface shouldn't have lightmaps. And it can't be eliminated, otherwise maps compiled without -splitspecial will crash the engine when trying to generate the surface caches. Right now, I'm using an if(!out->samples) statement to ensure that maps without lit water will have the SURF_DRAWTILED flag set. However, the engine loads the mtexinfo_t data through Mod_LoadTexinfo right before Mod_LoadFaces is called, so in theory it should be possible to replace the (!out->samples) check with a (texinfo.flags & TEX_SPECIAL) check. I'll modify the light tool to remove the "always save lightdata" hack, compile a map with it and change the check in the engine to see if it works.    #419 posted by mankrip on 2016/04/17 17:09:06 Yeah, it worked. Now instead of this: if (!Q_strncmp(out->texinfo->texture->name,"*",1)) // turbulent { out->flags |= (SURF_DRAWTURB | SURF_DRAWTILED); ... the proper way to set SURF_DRAWTILED is this: // mankrip - begin if (out->texinfo->flags & TEX_SPECIAL) out->flags |= SURF_DRAWTILED; // mankrip - end if (!Q_strncmp(out->texinfo->texture->name,"*",1)) // turbulent { out->flags |= SURF_DRAWTURB; // mankrip - edited :) Thanks for making me look into this.  Bounce Lighting Alpha  #420 posted by ericw on 2016/05/20 22:04:49 been fighting with this for a while now.. it's more or less in a finished state I think. windows builds source Command line flags: -bounce enables 1 bounce (this is all that's supported) -bouncedebug saves only the indirect lighting to the bsp/lit, for previewing -bouncescale scales the brightness of bounce lighting, default 1. can try 2 or 0.5 for more/less indirect light. -bouncecolorscale how much bounce lighting picks up color from the map textures, between 0 and 1. default 0 because this can lead to q2 style everything-is-gaudy. you can try 0.5 or 1. Note, this is slow! light uses visdata now, I recommend only using -bounce on vised maps because that speeds it up a lot. Other info: it works more or less like the existing "_surface" light system; point lights are generated on each face to bounce light back into the map. Currently there is no face subdivision for this, so the bounce light given off by really large faces will be coarse (all coming from just 1 point light).  Sounds Interesting  #421 posted by Breezeep_ on 2016/05/21 01:45:56 I'd like to see a screenshot showing the effect though.  NP  #422 posted by mfx on 2016/05/21 02:03:30 https://pbs.twimg.com/media/Cgwje1aWYAAn_Wf.jpg:orig left is with bounce, right is w/o.  Its One Light Source In This Particular Map Shot  #423 posted by mfx on 2016/05/21 02:04:23 mind you.  Breezeep  #424 posted by ericw on 2016/05/21 02:11:22 without with "Without" shot used "-lit -extra", 9seconds "With" shot used "-lit -extra -bounce", 39 seconds the 39 seconds is with 8 threads, and vised map though.

Of course it can be my lame '06.  Yeah  #446 posted by ericw on 2016/06/21 18:55:07 Use TreeQbsp if that works, or I'd recommend using rebb's version of BJP qbsp/vis: http://www.voidspark.net/projects/bjptools_xt/ The main thing in my tools is light.exe which has lots of new options.  Suggestion For Surface Lighting  #447 posted by Shamblernaut on 2016/07/23 20:22:32 Hey EricW, Forgive me if this functionality already exists, but I thought of something that would help with lighting control. Is it possible that a func_wall, func_detail or func_group be given a surface light flag for individual surface light control? The current setup (using the light entity) lights up each instance of the "_surface" defined texture, however there are times that I don't want every instance of that texture lit or times that I want different colours or intensities on said textures. Cheers.    #448 posted by ericw on 2016/07/25 18:26:55 Hmm.. I can see that would be useful, but I'm not sure if can be done easily. The surface light template (the light entity with "_surface" "xxx") can use any keys allowed on lights, so it would be messy to read those light keys from a func_detail/group/wall entity. As a workaround, creating a duplicate of the texture with a different name, along with a new surface light, might be the best option.    #449 posted by Rick on 2016/07/25 18:51:11 As a workaround, creating a duplicate of the texture with a different name, along with a new surface light, might be the best option. That's similar to what I did for my Jam 6 map. I used TexMex to make a custom jam666.wad specifically for that map. I had textures that were the same but with different names. One with surface light and one without.    #450 posted by Shamblernaut on 2016/07/25 21:30:09 Heya, yeah... That workaround... It feels like I'd be adding bloat to the map (not that it's an issue with such small textures or modern machines). I spent the last few hours looking through the code... It's a bit beyond my skills to modify it. But I think I'm slowly getting a handle on it. At the moment the program cycles through all entities searching for the key value "_surface", not just light entities. So it's possible to play around with lights on other entities, but there is no light drop-off with these. I suspect that this has something to do with geometry detecting as worldspawn? because the output: "Creating surface lights for texture "DOPEFISH" from template at ()" omits the origin. I thought that I might be able to modify the function to use a name key rather than a texture name for "_surface". Or modify it to read the colour and intensity keys from the geometry (as func_detail) rather than the light entity itself. Either way, I need sleep. I might come back to this later and have another crack at it.    #451 posted by ericw on 2016/07/25 22:30:56 Yeah, it's true duplicating textures adds some bloat. At the moment the program cycles through all entities searching for the key value "_surface", not just light entities I think that's an accident.. I'm currently reworking the entity handling code (on the master branch on github) to have a clear distinction between lights, bmodel entities, and other entities. "Creating surface lights for texture "DOPEFISH" from template at ()" omits the origin. Hmm, that is a bug. I thought that I might be able to modify the function to use a name key rather than a texture name for "_surface". Or modify it to read the colour and intensity keys from the geometry (as func_detail) rather than the light entity itself. The main problem with doing anything with func_detail/group in light.exe is the information about which faces correspond to the entity doesn't exist in the .bsp. I hacked something together for supporting a few keys on func_detail/group (_minlight, _phong, _dirt) but it was pretty awkward; the keys are parsed by qbsp, values packed into an integer so they can flow through qbsp's processing and are then dumped into an auxiliary file (.texinfo) which is then parsed by light.exe. My hunch is it's not worth jumping through all those hoops for this feature, but it could be done. btw, another workaround worth mentioning.. there is a "-surflight_dump" flag, which writes the generated lights to a file. so you can use "_surface" lights to generate a first draft version of the map lighting, dump the generated lights to a file, delete the "_surface" lights and paste in the generated lights, and then tweak them individually.  Bouncy Castles  #452 posted by Kinn on 2016/08/02 19:29:08 The bounce feature looks badarse. I have a question though - how are the bounce lights attenuated? Does the attenuation of bounce lights depend on the attenuation of the source lights?    #453 posted by ericw on 2016/08/02 19:51:51 The bounce lighting is hardcoded to use 1/(distance^2) for now, regardless of what the source lights used. What happens is there's a regular lighting pass, then the average light brightness / color received by each face is calculated, which is used to create lights for the bounce lighting pass. So this means a delay 0 (linear) light uses linear falloff for its direct light, but the reflected light acts more like delay 2. Hopefully this makes sense!  Cheers  #454 posted by Kinn on 2016/08/02 20:00:59 Sounds good! Another question - I understand a single "bounce light" is generated for each face. This sounds similar to the surface lights features. The issue I found with that was the intensity of light created depends on the density of faces on the surface - this is a problem I found particularly noticeable with large surfaces like liquids that get split in unpredictable ways. Is the intensity of bounce lighting affected in the same way? Or are the bounce lights created taking the face area into account?    #455 posted by ericw on 2016/08/02 20:16:41 Ah, yeah, I ran into that problem with surface lights as well, where lava was noticeably brighter around rocks that caused the face to be split up. Bounce lights shouldn't have that problem; they are scaled by face area, so the overall scene brightness should remain constant if faces are split up. I also found hotspots (where you could see the individual lights) were a problem with "_surface" lights - especially when used on things like lava. The bounce lighting has a hack to work around hotspots: there's a distance threshold of 128 units, where bounce lights have the same brightness within that distance.    #456 posted by Kinn on 2016/08/02 20:20:17 Ace biscuits :) Are you planning to use those bounce light ideas to improve surface lights in that regard?    #457 posted by ericw on 2016/08/02 20:50:45 Yeah, it's something I wanted to do!  Cool Beans  #458 posted by Kinn on 2016/08/03 10:47:09 Been playing around with bounce and it's super cool. Different topic...for me it seems _shadows 1 is broken now... Link to bsps and map files: https://drive.google.com/open?id=0B74rZcw0hvZpcmdUbnd1dndLckE Test case is a simple func_illusionary torch holder, with _shadows 1... temp01a.bsp, lit with tyrutils-ericw-v0.15.4-win32: http://i.imgur.com/aFzI3HK.png temp10b.bsp, lit with tyrutils-ericw-v0.15.5-win32: http://i.imgur.com/nGvFizl.png (ignore the fact that one shot has coloured light, and not the other - that was just me accidently invalidating the lit file when renaming the bsps)    #459 posted by Kinn on 2016/08/03 10:50:44 Note - it's not like shadows are disabled, in some cases, shadows are cast, but they are glitchy looking (e.g. the torch holder is actually shadowing the bit of floor at the base of the pillar, but the vertical sides of the pillar are ignored)  Thanks For The Test Case  #460 posted by ericw on 2016/08/03 21:19:08 will fix this.. It's related to how sample points are positioned on a face, by tracing from the face midpoint to the desired position and stopping at any obstruction. I made _shadow models obstruct this trace, which was a mistake, so it ends up sampling the light value above the torch holder for the samples that should be located under it.  Cheers  #461 posted by Kinn on 2016/08/03 21:58:06 nice one :)  _project_texture Lights  #462 posted by Kinn on 2016/08/05 17:45:29 Is it possible to flip / rotate the texture that a light projects?    #463 posted by ericw on 2016/08/05 19:40:10 The 3rd param of "_project_mangle" should be the "roll" value that controls rotation. btw re-posting from the jam thread: I think "_project_mangle" is buggy, the docs say it expects "yaw pitch roll" like a spotlight mangle, but I think it actually wants "pitch yaw roll". I'll fix that in the next light release to be consistent with spotlights, so it's experimental/unstable only for now. Also I think I fixed the bmodel shadow issue, hoping to make a new release soon!  Rock 'n' Roll  #464 posted by Kinn on 2016/08/05 20:12:03 Sorry, I'm a tard - roll totally works :} I guess I was just following the description of mangle in the readme (which said roll does nothing, so I didn't bother trying it) However, a way of flipping the image would also be real nice (for those asymmetric stained glass window textures).    #465 posted by Kinn on 2016/08/05 20:13:02 oh and awesome news re: the shadow issue - cheers :)  Darkplaces Lighting Fix - Rounding Of BSP Texture Vectors  #466 posted by Qmaster on 2016/08/11 03:09:43 Mapping Help, Post #15623: @dumptruck_ds I got a hack for qbsp that seems to fix the DP lighting issues in your map. Here is a test build: http://quakespasm.ericwa.com/job/tyrutils-ericw/ (I just added rounding for the bsp texture vectors, the same algorithm that is used for points - if a value is within 0.0001 of an integer, round it to that integer. It's not a proper fix but it seems to work decently well.) Ericw, I can't find where I downloaded this test build, do you still have this? Also, I found possibly a bug...maybe with JACK(hammer). When I compile I get a string of warnings: line 11: Unrecognised string escape - U line 11: Unrecognised string escape - J line 11: Unrecognised string escape - D line 11: Unrecognised string escape - Q These correspond to letters in the directory path after slashes in the .map file JACK generates. For instance: "C:/Users/Josiah/Dropbox/QUAKE..." Compiler thinks they are escape characters like newline n for instance. The map still compiles, it's just annoying to have warnings.    #467 posted by ericw on 2016/08/11 03:29:46 re: Darkplaces Lighting Fix: that stuff is in the most recent release (v0.15.5) at: http://ericwa.github.io/tyrutils-ericw/ Are you still having corrupt lightmaps in DP with this version? In my experience it only happens occasionally on faces with weird texture alignment (e.g. sheared texture). e.g. a few faces in ad_crucial.bsp from Arcane Dimensions have corrupt lightmaps in DP. about the escape sequences warning, yeah, it's confusing... I should probably just suppress the warning for the "wad" key of worldspawn.  Escape Sequences Mini-rant  #468 posted by Spike on 2016/08/11 05:15:37 there's nothing wrong with "c:/foo/bar/naff.wad". there IS a problem with "c:\foo\bar\naff.wad" because that contains a new line and two dodgy chars. "c:\\foo\\bar\\naff.wad" is fine of course, just ugly and specific to windows. there's an even bigger problem with "c:\foo\bar\" because that string isn't even terminated properly. And yes, I have seen that in maps, and yes it does screw things over, and yes I hate the idea of getting the engine to do special things just because of the name of the field. Its common enough that a terser and more specific warning would make sense, but I'd personally prefer if everyone just started using string markup consistently instead of varying depending on arbitrary field names. Idealism can suck sometimes.    #469 posted by ericw on 2016/08/11 08:10:01 I had a quick look at the winquake source.. these are my 2 cents: - Double-quote characters can't be escaped, whatsoever (COM_Parse). Winquake, DP, FTE all fail with parse errors if a trigger_once's "message" string is "foo\"bar" - The only escape sequence recognized by vanilla is \n, which gets converted to a newline character. (ED_NewString). Otherwise, the backslash and next character are left as-is. Writing paths like "wad" "c:\foo\bar\naff.wad" would only be dodgy if the engine/gamecode needed to use them. Everyone uses forward-slashes for paths meant to be read by the engine/QC though ("noise" "sounds/nnnn.wav", etc.) "wad" "c:\foo\" is not a problem because double quotes can't be escaped. A trigger_once with "message" "foo\" works fine in winquake, DP, and FTE (though FTE centerprints foo" instead of foo\ ) What would be a real problem is a wad path with double quotes in the directory/filename.. apparently that is forbidden on Windows, but OS X seems to permit it. Anyway, if anyone tries that, qbsp would fail to parse the .map file.    #470 posted by mankrip on 2016/08/11 19:43:18 How about making the compiler replace the backslash character with a forward slash, in the "wad" field only?    #471 posted by Rick on 2016/08/11 20:02:08 I always wondered why it couldn't just check the relative Quake path for any wads or just require that the wads be located in a specific folder.  @ericw, Continued Rant :)  #472 posted by Spike on 2016/08/12 06:02:34 enginewise, the biggest issue is that saved games and maps share parsing code. So double-quotes, new lines, carrage returns, and double-backslashes need to be saved, and thus also need to be reloaded. Otherwise mods will break - or at least mods designed for engines that can actually do string manipulation, anyway. Whether that's consistent with winquake is somewhat irrelevant from my perspective - as you say, the only place backslashes would ever really be used in a map is in the wad key, or before an 'n'. I'm personally okay with FTE breaking compat from winquake to ensure saved games work, so long as embedded chars are rare and don't corrupt other strings. small correction: FTE's entity parsing is actually performed by qclib's misleadingly named QCC_COM_Parse - which includes consistent escapes and a special hack for "c:\foo\" in an attempt to prevent the map from being unusable. This is why you get foo" instead of foo\ - because FTE saw an escaped double-quote. The wad field *IS* parsed by engines in the case of halflife bsps, where named wad files may be required for external textures. The paths are ignored (absolute paths are a definite no in something that has been shipped/released), but if they arn't escaped properly then wads starting with an n will still get messed up (clients with download mechanisms might also attempt to download such wads from servers). Additionally, fte can load .maps directly, although wad handling there is curently kinda screwed up thanks to replacement images overriding things and confusing sizes. @mankrip, really its the editors that should be doing that, especially for relative paths which would allow such maps to still be compiled/loaded on linux/mac as well as windows. Obviously absolute paths are problematic regardless. @Rick, some -basedir argument for qbsp?.. and probably -game too...  Spike  #473 posted by mankrip on 2016/08/12 15:51:54 @mankrip, really its the editors that should be doing that I agree that fixing this in the editors would help for when creating new maps, but for compiling old maps it wouldn't, specially if the user wants to compile some old maps directly from the commandline. The Quaddicted database has tons of maps with source available, and sometimes it's useful to recompile them without modifications, when all the user wants is to compile them in a different way (e.g. enabling translucent liquids or lit water). So, an ideal solution would be to fix this both in the editors and in the compiler - fixed editors would ensure that the maps can be compiled by any compiler, and fixed compilers would accept maps from any editor.    #474 posted by Spike on 2016/08/12 20:05:21 even if you are recompiling it without any other edits, you'd probably have to fix all the wad paths anyway. tbere's enough existing maps that auto-correcting the wad paths for any new ones is a little insignificant. I would personally rather that editors were aware of \", \n, \r, \\ when loading rather than \ getting switched to / in specific cases that 'the' engine will already need to deal with regardless. 1 well-worded warning is imho useful, 4 is excessive but still preferable to none. on a related but different note, casually recompiling all your maps isn't something I can really endorse - if you do this, you'll find yourself kicked from vanilla quakeworld servers due to having an assumed-cheat version of the map. vispatches and lit files won't trigger this issue, and can automatically run on maps without worrying so much about which qbsp originaly compiled it and how strict it may have been. This won't give you everything, so there's no single winning solution, but it should give more consistant+reliable results if you're doing it in bulk. Assuming those tools support bsp2 etc, anyway.    #475 posted by Rick on 2016/08/12 20:30:30 @Rick, some -basedir argument for qbsp?.. and probably -game too... Something like that I guess. Netradiant wants the wads in the ID1 folder. Put them there and it works fine, anywhere else and you have no textures in the editor. Frequently I dig out old maps from years ago and run them through QBSP and get no textures errors. Then I have to go manually edit to fix "wad" "E: \\ worldcraft \\ test.wad" or whatever I was using back then. I'd rather the map just used "wad" "wadname.wad" and let the compiler find it (with the assumption that the wad is somewhere in the Quake folder).  Does Your QBSP Support Decimals As Texture Offset Values?  #476 posted by negke on 2016/08/14 13:46:15   Yes  #477 posted by ericw on 2016/08/14 18:47:27   Who Else Would Need To Move Textures By Fractions Of Pixeks  #478 posted by onetruepurple on 2016/08/15 21:38:55   After You Rotate A Texture Probably  #479 posted by Kinn on 2016/08/15 21:41:18     #480 posted by metlslime on 2016/08/15 21:50:51 yeah, if you do the classic 1:4 2:4 3:3 4:2 4:1 cylinders, you will have some angles that you can't perfectly line up the textures on with whole degrees. Not noticeable until you have a long enough surface with the same angle  Ahoy  #481 posted by Shamblernaut on 2016/09/07 21:22:36 I'm getting this error with my map: light: /home/benny/Downloads/tyrutils-ericw-ericw-v0.15.5/light/light.cc:656: void CalcualateVertexNormals(const bsp2_t*): Assertion `smoothedNormals.find(v) != smoothedNormals.end()' failed. As well as a bunch of: WARNING: couldn't nudge light in solid at -1586.848267 174.062302 507.337677 Which I assume is because some of the surface light textures cover the entire brush and some are against other solids.

You have to run a full qbsp to update the .texinfo file though. btw hoping to make a new release pretty soon  Thanks  #483 posted by Shamblernaut on 2016/09/08 09:00:14 the new version compiled and works a treat. also the "-gamma" command is amazing, saved me having to decrease all my light values after adding -bounce  Dirtmapping Lit Liquids Bug  #484 posted by mankrip on 2016/09/09 01:11:18 Liquid surfaces should be completely ignored when dirtmapping, but they aren't. Here's an E1M2 screenshot. Ideally, lit liquids shouldn't receive or emit dirtmaps.  Addendum  #485 posted by mankrip on 2016/09/09 01:14:36 I've taken that screenshot with the water fully transparent, and the map was compiled with these parameters: $bsp_exe -nopercent -splitspecial$bspdir/$file$light_exe -extra4 -dirt -dirtmode 1 -dirtgain 0.875 -dirtscale 1.5 $bspdir/$file  What If The Liquid's Supposed To Be Opaque?  #486 posted by Kinn on 2016/09/09 01:16:44     #487 posted by khreathor on 2016/09/09 01:25:26 "_dirt" "n" For brush models, -1 prevents dirtmapping on the brush model.

Maybe it will work with water brush too?  #487  #488 posted by mankrip on 2016/09/09 01:48:39 I've just tried it, and _dirt -1 doesn't work on func_detail.  Addendum  #489 posted by mankrip on 2016/09/09 01:51:33 Well, actually _dirt -1 sort of works on func_detail. The water isn't dirtmapped now, but it still casts dirtmapping in the rest of the world model.    #490 posted by ericw on 2016/09/09 01:58:45 Thanks for the report, I will fix it properly. Probably I'm checking for TEX_SPECIAL and skipping casting/receiving dirt if that is set, need to also check if the texture starts with "*" or "sky" in case splitspecial is used.    #491 posted by mankrip on 2016/09/09 02:03:46 Thanks. A little feature request: Can you add individual options for -splitliquids and -splitsky? This would be more optimal than -splitspecial, since there's usually no reason to allow sky surfaces to be lit.    #492 posted by ericw on 2016/09/09 02:08:15 It should be there already, just called -splitturb instead of -splitliquids  :) Indeed  #493 posted by mankrip on 2016/09/09 02:29:46 It is; I've tried it out, and it worked. Thanks, I've updated my compiler parameters.  Actually  #494 posted by Kinn on 2016/09/09 21:38:30 Gosh I had no idea lit liquids were even supported in this tool.

It's something like 2-4x faster depending on the map. Also fixed the regression with bmodels touching the world that Kinn reported. full changelog: https://github.com/ericwa/tyrutils-ericw/releases    #496 posted by onetruepurple on 2016/09/09 22:39:29 minlight no longer bounces I can't even begin to imagine how that worked or looked.    #497 posted by mankrip on 2016/09/10 02:04:06 V0.15.7 isn't compiling at all here. ** Executing... ** Command: C:\Dev\Tools\tyrutils\bin\qbsp.exe ** Parameters: -nopercent -splitturb C:\Projects\QuakeDev\Game\Quake\_QDebug_\maps\E1M2 * WARNING: File was not built!

In the meantime, I've confirmed that the worst part of the dirtmapping bug is now fixed; liquids won't cast dirtmaps on the world anymore. They still receive dirtmaps, but at least this problem can be worked around by func_detailing them with _dirt -1: screenshot.  Fast!  #502 posted by ＰＲＩＴＣＨＡＲＤ on 2016/09/10 05:19:24 Wow, 0.15.7 is incredibly fast! I don't have specific times, but it speeds up light on my map by a huge amount. No idea what kind of wizardry was performed for this, but it's really cut down on the iteration time for my map. Thanks so much!    #503 posted by ericw on 2016/09/11 03:14:49 Pritchard - awesome :) got some bugs reported and fixed already (to be in the next release): - the "unmatched" target warning was broken - skip-textured func_'s with "_shadow" "1" were broken (for making invisible shadow casters) This one was tricky due to how I migrated light away from using the BSP for raytracing. The workaround I implemented has a limitation that the entire bmodel has to be textured with "skip", otherwise the skip textured bits don't cast shadows. Hopefully this covers the common use cases for that trick, though.  Mankrip  #504 posted by Breezeep_ on 2016/09/13 02:08:16 That looks pretty damn cool. How did you get the water to draw shadows like that?  Only A Warning, I Assume This Isn't A Big Issue  #505 posted by Shamblernaut on 2016/09/13 10:40:18 thought I would report it just in case. vis.c: In function �LoadPortals�: vis.c:1120:9: warning: ignoring return value of �fscanf�, declared with attribute warn_unused_result [-Wunused-result] fscanf(f, "\n");  #504  #506 posted by mankrip on 2016/09/14 07:09:03 Using independent surface caches for texture & lighting, and combining them in realtime. The drawing routines of liquid textures (and now, of power-of-two textures too) were mixed with the drawing routines of regular surface-cached routines, combining the texture & lighting in realtime before blending the result into the framebuffer. It's not difficult to do, just really tedious. Involves modifying and rewriting a lot of code.  Func_viscluster Support  #507 posted by Qmaster on 2016/09/16 04:32:51 @ericw: I'm curious if it would be possible to add support for func_viscluster brushes in order to negate large open spaces. I'm of course assuming that vis leafs automatically chop up empty space into leafs every 1024 units. https://developer.valvesoftware.com/wiki/Func_viscluster Spikespasm: Host_Error: Mod_LoadLeafs: 121741 leafs exceeds limit of 70000.    #508 posted by ericw on 2016/09/16 04:44:11 AFAIK, there is no chopping of space every 1024 units in this qbsp, that feature was added in quake 2's. func_viscluster - this sounds like purely something to speed up the vis computation. It's probably possible to add to Q1 tools, it wouldn't help with reducing the number of leafs though.  Strange Bounce Bug  #509 posted by ＰＲＩＴＣＨＡＲＤ on 2016/09/19 09:25:04 This just popped up now as I'm working on my map. Bounce lighting started generating random black spots in this one room of my level: screenshot 1 Here's how it looks with bounce lighting turned off: screenshot 2 Any idea what's causing this? I was changing my light entities around, but I can't figure out what I did that caused this. Has anyone even seen this before? Help would be greatly appreciated :s    #510 posted by ＰＲＩＴＣＨＡＲＤ on 2016/09/19 09:31:25 At least somebody's happy about this... I tried running the map through 0.15.5 and the issue went away. I'm guessing then that this is an issue caused by the new approximation methods in 0.15.7...  I Should Really Try Before I Speak...  #511 posted by ＰＲＩＴＣＨＡＲＤ on 2016/09/19 09:33:44 I hate making a third post like this, but I tend to write in a very "stream of consciousness" manner...

I'm guessing it is some kind of regression from 0.15.5, although I couldn't say what other than that it seems to be bounce-related.  Fixed!  #514 posted by ＰＲＩＴＣＨＡＲＤ on 2016/09/20 11:01:34 I got an email back from eric and the bug was fixed. Thanks for the quick response! :)  Please Help Me?  #515 posted by Newhouse on 2016/09/21 20:30:33 Could somebody help me with this little thing that annoys me so much : https://drive.google.com/file/d/0BwxYkKdSD855Mzhuc3ViNVo5YzA/view?usp=sharing    #516 posted by khreathor on 2016/09/21 20:46:03 can you turn off texture filtering in game and see if this still happens?    #517 posted by metlslime on 2016/09/21 20:52:55 bilinear filtering -- the last row of pixels blends with the first row of pixels, since it's a tiling texture.    #518 posted by Rick on 2016/09/21 21:43:22 In the black/red colored view it looks like the texture is mirror imaged. Is it one continuous surface going from from red to black or is it actually two different brushes?  Rick  #519 posted by Newhouse on 2016/09/21 22:25:28 It is same exact texture but one of axis is mirrored "-1" it is 128x128pxl, and those brushes are exactly 128x128 and next to each other.. so filtering is making this to happen, that is looks like it is.. like 0.5 pixels or something?    #520 posted by Newhouse on 2016/09/21 22:26:58 ..so filtering is making it to look, like it is 0.5 pixels off or something*    #521 posted by metlslime on 2016/09/21 23:20:15 get up close and toggle between gl_nearest and gl_linear and you'll understand what's happening. You'll need to hide this pixel-wide blend by not using the full width of the texture on that polygon. Either scale it up slightly or make the polygon slightly smaller.    #522 posted by Newhouse on 2016/09/22 16:21:30 Thanks metslime, I haven't tried scaling up yet - maybe that will work.    #523 posted by Rick on 2016/09/22 16:57:40 Any time there is a difference between the textures on adjoining surfaces there will be a noticeable line if GL filtering is used. I call them GL seams, and any kind of rotation, x/y shift, flip, mirror, etc. will cause it. Even just pixel color differences will cause it.    #524 posted by Newhouse on 2016/09/22 17:52:55 It is interesting.. it really looks like there isn't different pixels in this case, if I understood what you meant by that. I have no clue how GL filtering works, so basically I can't avoid these things to happen. For example I should create texture that points out on every main angle? Then I should have seamless street texture to fill everything in middle.. I was trying to create streets which has some messy garbage on both sides but middle is a lot cleaner. It really seems like that brown/black line in middle is like texture's starting pixel line, because its end and beginning has different pixel colors. The way GL filtering works.. does it look every texture individually and doesn't care about rotation, x/y shift, flip, mirror at all and that is why something like this happens sometimes?    #525 posted by Newhouse on 2016/09/22 17:55:05 Does it try to blend blend pixels with next pixels.. if I offset it by 1 it is already in beginning, so it tries to blend with those pixels?    #526 posted by Rick on 2016/09/22 18:17:01 What I did when making a series of similar textures was to create one common frame to use for all. Basically just the outer 1 pixel border of a 64x64 square. I used that to make different variations where the middle part was different but the pixels around all four edges are exactly the same for all. For 128x128, I just repeated the 64x64 frame. Textures made this way have no GL filter seam/line as long as they meet at the 64 unit boundaries. To make sure no weird texture alignments happen, I never use texture lock. I only turn it on if I really need it.  It Blends The Next Pixels, So Yes The Dark Pixels Are Wrapped Around  #527 posted by Qmaster on 2016/09/22 20:03:04 I thought we would have moved on from GL filtering as a society by now. Horrible concept really. Yay filtering. Let's blur all the textures. No glasses for you and contacts thrown away for you and baske in the glory that is nearsightedness on a screen. (P.S. I'm nearly blind and need powerful contacts so I may be biased.) Also this blending is not a compiler issue. The adjacent face has a different texture alignment and therefore is split into a separate face for blending purposes but thats the extent of compiler related.    #528 posted by Newhouse on 2016/09/22 20:03:06 I might have used texture lock too much.. sometimes it was just left pressed down. Checking something like that multiple times, especially when placing lamps and such things confuses a bit. I must be weird, because in some cases I want to have more control over things how wide/high some brushes should be.. and if there is only texture available that is 32x32 for example, but I want it to be 16x32 or 32x16 I have to cut it and offset other half so 'borders' are in right place. Creating new textures sounds like, I would probably fail at trying, I'm not an 2d artist by any mean.    #529 posted by Mugwump on 2016/09/22 20:12:37 You could split an existing texture in two halves in PhotoShop, then use them in your maps. This way you wouldn't have to offset your textures, which can be tedious.  Its So Simple To Fix  #530 posted by Kinn on 2016/09/22 20:56:49 Just make the road so there's three brushes across the width instead of just two.    #531 posted by Newhouse on 2016/09/22 21:01:08 Thanks Kinn, but I also tried out.. scaling up a bit and it worked. But if I need to do wider roads.. then I need to use your advice.  Re: Ericw, Mapping Help Thread Post #17150  #532 posted by former_total_newbie on 2016/09/23 16:57:45 don't worry, Linux package management just sucks.. what's the error? I have hit the same thing on debian/ubuntu before, there's some magic flag to make apt-get work usually. also maybe we should move this to the OS thread...? Thanks for being willing to look at it. Initially when I typed "cmake .. -DCMAKE_BUILD_TYPE=Release" from within a newly created "build" directory as per the instructions that come with tyrutils-ericw, I was told that I had to install cmake using apt-get ... which I did, and then weird things happened.* I thought the installation of cmake failed, because I still could not get the build process to work. I had another look, though, and it seems like the installation did work, but I need a higher version of cmake than the one that is in my OS's repositories: cmake .. -DCMAKE_BUILD_TYPE=Release CMake Error at CMakeLists.txt:1 (cmake_minimum_required): CMake 3.1 or higher is required. You are running version 2.8.12.2 -- Configuring incomplete, errors occurred! ...which means I need to compile cmake from source, I guess? *If you're interested, I can post the weird stuff that happened too. Basically, as soon as I typed "sudo apt-get install cmake", the terminal window was taken over by the drupal configuration/installation process, which keeps failing. This happens whenever I type "sudo apt-get install cmake" again.    #533 posted by ericw on 2016/09/23 21:19:51 OK, the problem is on my end; I thought I supported Ubuntu 14.04 but mixed up which cmake version it had. I'll see if I can adjust the cmake script and report back..  @total_newbie  #534 posted by ericw on 2016/09/23 23:24:54 Ok, I made some changes and updated the instructions for Ubuntu 14.04 x86_64: https://github.com/ericwa/tyrutils-ericw#ubuntu-1404 If you are running 32-bit there will be more work to do but it should be possible as well  Correct Link  #535 posted by ericw on 2016/09/23 23:25:22 Absolute Path Not Possible With Qbsp.  #536 posted by Lurq on 2016/09/24 17:43:26 Not sure this is a bug, since it look deliberate in the code, but it would be interesting to know why. :) It treats any argument that begins with a '-' or with a '/' as a switch. Absolute path (linux), including relative to home, will begin with '/'. Anyhow.

Specifically looking to find the "Detail Nodes facing the Void". I can use q3map2 to find normal entity leaks, but it doesn't work for func_stuff. Is there an easier way than hunting through the map seams?    #541 posted by ericw on 2016/09/26 21:53:14 The main idea is to use the pointfiles (mapname.pts) output by qbsp/txqbsp. The quake engine can load them with the "pointfile" command. I use Trenchbroom to load them. re: "Detail Nodes facing the Void" warning, this is unique to how func_detail was integrated into Quake tools. It's not the same as a leak.. as far as I know, the only problem that warning can cause is reduced vis quality (the fact that this is an issue at all may be a bug in vis, not sure.) To avoid the warning: having world brushes seal in the func_detail is not good enough, because detail clips away world, and the warning happens after the CSG phase when every brush is clipped against every other one. You want to ensure there are some non-detail *faces* left in the final bsp (what you see in-engine) that, if you extend the planes they are on, enclose all of the detail faces. e.g. if you have an outdoor area where the entire floor is detail, I think you will get that warning  Func_detail  #542 posted by Qmaster on 2016/09/28 00:30:06 So, I did some experimenting and func_detail can actually be used to seal the map. Um...what?? Also, func_detail brushes are still being used to slice up the space into more and more leafs. Again...huh?? So func_detail is essentially worthless except to speed up vis then? I could use func_wall to save on leafs and not worry about leaks mysteriously showing up when I hide the (leak would be there anyway). I thought the point of func_detail was to not affect vis, like, at all. No leafs added, no slicing other brushes. Is it possible for func_detail to work like in Source: https://developer.valvesoftware.com/wiki/Func_detail    #543 posted by FifthElephant on 2016/09/28 00:46:40 func_detail will always cut up brushes. It's sole purpose is to speed up vis.  Purely Out Of Interest  #544 posted by Kinn on 2016/09/28 00:51:27 Assuming latest ericw tools are used, what are the downsides of using buttloads of func_wall in place of func_detail?    #545 posted by FifthElephant on 2016/09/28 00:55:11 func_wall lighting might get a bit funky. You'd have to remember to include things like _shadows and _dirt etc. That's the thing I can think of mostly being affected.    #546 posted by FifthElephant on 2016/09/28 00:57:22 The other issue with using brush entities is that you are contributing to the entity count. If you're trying to stay under 255 ents for extra compatibility I guess then it's better to stick with func_detail.    #547 posted by ericw on 2016/09/28 01:19:20 func_wall downsides: - counts towards entity limits (I guess they are probably static ents?) - likely will have overdraw? - they can have different rendering performance quirks depending on the engine (and how well the GL driver optimizes what the engine is doing). Quakespasm: there is some setup cost per-func_wall rendered, but they use the same drawing code as the world, so they can have lots of faces and still render fast Fitz085 and I believe MarkV use R_DrawSequentialPoly which scales badly on funcs with lots of faces    #548 posted by ericw on 2016/09/28 01:36:32 Also, func_detail needs to create leafs, otherwise collision wouldn't work, rendering might break depending on the engine. The engine needs to have been designed with func_detail in mind to support not creating leaves (q2/q3/source?).  Func_wall Lighting  #549 posted by Qmaster on 2016/09/28 01:57:05 Ok. On a related note, can func_wall have keys added to receive and block lighting identically to a func_detail.  Yep  #550 posted by ericw on 2016/09/28 02:14:48 "_shadow" "1"  You're The Best, Thanks!  #551 posted by Qmaster on 2016/09/28 02:27:28     #552 posted by Ubiquitous on 2016/09/28 14:15:20 Is there a simple reason why the light tools can't be extended to produce lightmaps of essentially arbitrary resolution? More generallly, -extra 4 is still producing aliased shadows for me (e.g. here: https://ubiquitousgame.files.wordpress.com/2016/09/01.jpg). Is there anything I could try to get better looking lightmap resolution?  #552  #553 posted by Kinn on 2016/09/28 14:29:49 It would require new file formats and engine support I would imagine. This was thoroughly investigated a while back and actually got working, and from what I remember the feedback went something like: "Oh this is cool but a bit too sharp actually, can the shadows be made softer?" (makes it softer) "Hmmm, even softer?" (makes it even softer) "...softer still?...ok actually on reflection I think quake's default lightmap resolution actually looks better but thanks anyway ^_^"    #554 posted by dwere on 2016/09/28 14:34:06 I imagine the tools to generate the lightmaps weren't as good then? From what I can tell the quality of lighting improved quite a bit in the last N years.  Lightmap Resolution Is Tied To Texture Resolution  #555 posted by mankrip on 2016/09/28 14:37:35 This is a limitation of the vanilla BSP format. Lit2 solves it, but only a few engines supports it.  #554  #556 posted by Kinn on 2016/09/28 17:35:58 I think it was only something like one year ago when this was explored. Might be wrong - my temporal awareness is somewhat shoddy to say the least.  #552  #557 posted by khreathor on 2016/09/28 19:14:12 what about "-soft 2" or even more?    #558 posted by Spike on 2016/09/28 19:41:06 higher-res lightmaps have their perks: http://triptohell.info/moodles/junk/fte-20150311190731-0.jpg the biggest issue is that lightmap changes (both flashing lights and dlights) become abusive, which essentually requires multithreading and/or rtlights in order to prevent it being unplayable, which greatly limits the number of engines willing to implement it. crank it up to max and the bsp files become insanely huge, but that's only to be expected from poor-man's megatexture. :) either way, the stepping issue doesn't really go away. the only way to fix that is to use cubic filtering instead of linear filtering. currently this requires custom glsl. I really ought to investigate it some time. :s    #559 posted by ericw on 2016/09/28 19:54:10 I think there is also some room to improve the filtering within light.exe.. it's using a box filter for -soft and -extra, which is the worst possible filter, I want to try lancosz or others. Anyway to get the best quality currently you should combine -soft and -extra4. -extra4 alone will be sharper but have more aliasing    #560 posted by Ubiquitous on 2016/09/28 20:08:56 Thanks for the explanation all    #561 posted by metlslime on 2016/09/28 20:21:17 the biggest issue is that lightmap changes (both flashing lights and dlights) become abusive, which essentually requires multithreading and/or rtlights in order to prevent it being unplayable, which greatly limits the number of engines willing to implement it. As an aside, I've always thought the ideal handling for light styles would be to upload the four styles as 4 separate textures and combine them using multitexture (or multiple passses) when rendering. Are there any engines that do this?    #562 posted by Spike on 2016/09/28 20:36:46 rmqe does, iirc. my engine that tries to draw the entire worldmodel in a single draw call also does. the fragment shader is a bit faster if you do all 4 lightmaps with a single texture, at least when there's no lit support. you can then do the style->value lookups in the vertex shader and your fragment shader basically gains only a dot4product compared to a luma texture.  Its A Bit Hacky  #563 posted by Shamblernaut on 2016/09/28 20:56:43 but couldn't the engine be modified to interpolate hard edged shadows?    #564 posted by mh on 2016/09/28 21:16:53 As an aside, I've always thought the ideal handling for light styles would be to upload the four styles as 4 separate textures and combine them using multitexture (or multiple passses) when rendering. Are there any engines that do this? I also have working, but unreleased, Q2 code that does this. It also needs 2X modulate support, but in practice anything that's not of 3DFX vintage has that. It's possible with basic GL_ARB_texture_env_combine but much easier (and nicer) with shaders. The basic formula is texture * light0 * style0 + texture * light1 * style1 + texture * light2 * style2 + texture * light3 * style3, or texture * (light0 * style0 + light1 * style1 + light2 * style2 + light3 * style3). You can do it with multitexture and a single shader, substituting 0 for the style value (and using an all-black texture) for styles that a surface doesn't have. Pros is code simplicity, everything goes through the one code path, fewer state changes; con is extra texture accesses. You can do it with multitexture and 4 separate shaders, trading off texture lookups versus state changes. You can do it with multipass and a single shader; similar tradeoff as above but with added overhead of extra draw calls too. Fastest way is if you've monochrome lighting so it becomes a single texture access and a dotproduct: texture * dot (lightmap, styles). Performance is similar to stock GLQuake for scenes without many lightstyle animations; it's one of those optimizations where you shouldn't expect it to double your framerate in DM3, but if you play a map with lots of lightstyles it works great. What's nice is that you can then add lightstyle interpolation to the engine and get it for free. For dynamic lights you do something similar to RT lights which works much nicer for MDL files because you've now got proper directional shading and attenuation on them instead of them just being uniformly lit.    #565 posted by metlslime on 2016/09/28 21:39:12 Pros is code simplicity, everything goes through the one code path, fewer state changes; con is extra texture accesses. Would the texture accesses problem be solved by making sure all 4 styles end up on the same texture atlas? Or is it just the literal lookup into 4 different pixel locations? And is that anywhere near the cost of uploading new textures?    #566 posted by mh on 2016/09/28 21:47:13 Or is it just the literal lookup into 4 different pixel locations? And is that anywhere near the cost of uploading new textures? It's 4 different locations, one for each style. It can be mitigated by replacing texcoords for unused styles in a surface with {0,0} (so that the lookup will be in the GPU's texture cache) or by using a 1x1 black texture for lightmaps of unused styles (same reason), but again we're getting into state change tradeoffs. Comparison with cost of uploading new textures is an "it depends" answer. If you've a switchable lightstyle like the ramp in e1m1 then uploading is going to be faster. If you've a room with hundreds of surfaces each of which has multiple torch flicker animations on it, then uploading is going to be slower. On balance I think that irrespective of which method you use to handle animation, it's the right kind of optimization. What's already fast either remains fast or drops a little, whereas performance of what's slow comes up and best case is levelled.  Double-post  #567 posted by mh on 2016/09/28 21:49:44 I forgot to mention this. Rather than using 4 textures, one for each style, with 3 of the RGBA channels used and the 4th unused, an alternative is to use 3 textures, one for each of R, G, B with the styles packed into the 4 channels. That both saves memory and reduces those 4 lookups to 3.  Why 4?  #568 posted by ＰＲＩＴＣＨＡＲＤ on 2016/09/29 00:02:31 Seeing as we're talking about lightstyles etc. right now I thought this would be a good time to ask: had there ever been an attempt to raise the number of lightmaps past 4? I ask because as a mapper i've run into the issue a few times, and its pretty annoying when it crops up. i understand the need for such a low limit in the past, but is there any particular reason other than a desire for compatibility that we still have it? I can't imagine that there are many computers today that struggle to switch lightmaps frequently...  Why 4?  #569 posted by mh on 2016/09/29 00:12:19 It's not a problem for RT lights. For lightmaps it would need BSP format changes as well as engine and tool changes. I don't know/can't remember why we didn't do it for BSP2.    #570 posted by ericw on 2016/09/29 04:40:16 One thing that may help, in the next release I made light.exe not blow up when the "too many light styles on a face" warning happens. It will compute all the light styles and then save the brightest 4 per face.    #571 posted by ＰＲＩＴＣＨＡＲＤ on 2016/09/29 05:11:41 There'll still be a warning, right? Not knowing why you're not getting the desired results would be pretty frustrating and cause a lot of forum posts!    #572 posted by ericw on 2016/09/29 05:16:50 Yep the warning is still there    #573 posted by mh on 2016/09/29 15:56:41 One of the quirks of Quake, in terms of engine, tools and formats, is that it's stuffed full of hard-coded magic numbers like this that can make extending limits while retaining compatibility sometimes impossible. Unless you actually knew, you'd think that it would be reasonable to suppose that each face structure would have an int member indicating how many lightstyles it has. I know I'd think that. So you might be surprised to learn that it actually doesn't - instead there's a flat array of 4 styles and that's fixed by the BSP format. What's even more fun is that the code is littered with cases where sometimes a #define is used but other times the number 4 is hard-coded.  Ctrl=f "4", Replace "x"  #574 posted by ＰＲＩＴＣＨＡＲＤ on 2016/09/29 17:11:19 That does sound like great fun. I like to daydream about one day just taking quake and gutting it and building something similar that's barely compatible but much more friendly and so on. Really just daydreams though, I don't know C. And I don't want to really deal with fun  _project_texture  #575 posted by ＰＲＩＴＣＨＡＲＤ on 2016/10/03 03:25:01 I've been wondering if I could use this feature to get smooth blends of textures for my map, i.e. a gravel path that fades smoothly into grass, but unfortunately all that _project_texture seems to do is basically tint the colour of the light a bit, with some textures that have significant colour differences producing multi-coloured lights Part of me thinks that this is something that just can't be overcome; an issue with lightmap resolution, or something like that. But I feel like I should still ask; is it possible to get more fidelity out of this? If it's already possible, how do I do it? It's hardly dealbreaking if it's infeasible, but it'd be nice to have...    #576 posted by Spike on 2016/10/03 03:54:59 texture projections are still just a lightmap trick, so there's a resolution of 1/16th of your normal res. think of it as just a filter over the light, projected by a single side of a small cube around the light (you can distort the cube a bit by using the fov, the other 5 faces of the cube are black). so yes, all it does is basically tint the colour of the light. which means that if you make some white image and scale that up 16-fold, then you'll get the same lightmap res as the nearby textures without depending on engine extensions (lit2 would allow you to scale the lightmap per-func_detail without needing new textures). But... you'll probably end up shining light on the neighbouring surfaces too, so it'll be a bit too hard to control. it'd be nice to do some sort of alpha blending from one side of a face to another, for a nice blend, but politics and compat issues would make that an absolute nightmare. If you really want that, q3bsp+terrain shaders is the only proper answer right now.    #577 posted by ericw on 2016/10/03 04:07:31 The only portable (across engines) way to increase the lightmap resolution is kind of a hack, scale up a texture by 2x in the wad file (e.g. 64x64 to 128x128), and then use a texture scale of 0.5 in the map editor. _project_texture only really works for stained-glass windows like spike's screenshot in post #558. Another point: the projected texture will look less like mush if it's projected over a larger area / further from the light source. For texture blends the best bet is just make custom textures or use a wad with them. Even ignoring the resolution issue, the lightmaps are multiplied by the texture colors, so it would look like grass projected on top of rocks etc.  Oh Well  #578 posted by ＰＲＩＴＣＨＡＲＤ on 2016/10/03 04:48:27 I figured there would be issues like that. My gravel path shall continue to fail the existence test. Thanks for the explanation though, good to have my suspicions confirmed.  Pritchard  #579 posted by Mugwump on 2016/10/03 05:46:49 I remember some fantastic-looking hi-res textures of earthy/rocky paths blending into the grass on the sides, made for Oblivion. They might not be exactly what you're looking for but they could be worth checking out for inspiration.    #580 posted by ＰＲＩＴＣＨＡＲＤ on 2016/10/03 06:09:23 It would be nice, and maybe i'll take a look in that direction, but i'm not too invested in this idea and frankly finding an appropriate wad or making one myself would take far too much effort for the results i'm looking to get. You can see where the path would go here, on the grass with the two dogs. It's a pretty small area and so i'm just going to drop the issue now.  There Is An App  #581 posted by Shamblernaut on 2016/10/03 08:29:23 Called quake texture tool. Allows you to blend two textures together. I've tried it and it gives mixed results.

The hexen textures have a very nice blend into the dirt texture, with defined blades of grass that'd make it difficult to capture the same effect with brushwork (i'd say impossible). Trying to make up for texture deficiencies with brushwork is normally a losing battle. Quake's gridsize only goes so small, after all.  Pritchard  #588 posted by Kinn on 2016/10/03 15:52:37 Just fire up Zendar and look at the ground in the opening valley. That sort of thing is the best way of doing it I think. Quake's all a bit "squint your eyes and it kinda works".

I'm not really ashamed of how much I'm abusing the feature, it's a wonderful way to get smooth, soft lighting (those jagged edges are with soft and extra4!). I try to rely on visible sources where possible so having them reach as far as possible is a great help in a lot of ways. I will say though that it's a shame it doesn't work for switchable lights! That's how I ended up with that before and after pic, adding a targetname to the light...

I haven't reached the point where I try this feature yet, but I bet it indeed saves a lot of time by making the placement of additional ambient lights unnecessary. "I will say though that it's a shame it doesn't work for switchable lights!" Hmmm... Eric? Would that be within the realm of possibilities for a future update?  Styled Lights Bounce  #599 posted by ericw on 2016/10/04 21:38:42 I'll look into it! It was something I left out initially to keep things simpler. Nice screenshots!  The "Brush Primitives" Map Format  #600 posted by Kinn on 2016/10/04 21:50:15 Any chance of supporting the "brush primitives" map format (like how we support Valve 220) ? As far as I am aware, the "brush primitives" format was introduced for Quake 3 engine games, and is supported by GTKRadiant-based editors. It's like Valve 220 in that it allows textures to be projected properly on the brush face, instead of just the coordinate axes. I don't know too much about it, but there's an overview of the various map formats here: http://quark.sourceforge.net/infobase/src.topics.face.html  #599  #601 posted by Mugwump on 2016/10/04 22:05:36 Cool!  Brush Primitives  #602 posted by ericw on 2016/10/04 23:02:01 Should be doable, I imagine I can just grab the code from q3map2. I'll just need to find q3 map sources that use that format to test it with.    #603 posted by Kinn on 2016/10/04 23:05:04 That would be ace biscuits :) It would allow better texturing possibilities for Radiant users, of which there are quite a few here :)  @Kinn  #604 posted by khreathor on 2016/10/05 03:03:18 Like what? Some examples?    #605 posted by ericw on 2016/10/05 03:54:39 It's just another .MAP texture alignment format equivalent to Valve 220 and Quark ETP    #606 posted by ericw on 2016/10/05 08:38:29 I think I got brush primitives working - alpha build! Hopefully radiant can be configured to use brush primitives and quake 1 textures at the same time. I only really tested the texture alignment with a brush primitives map saved with Quark, although I did check that a map saved with the new netradiant can be parsed, so will be interesting to see if this works.  Next On The Docket  #607 posted by PyroGXPilot on 2016/10/05 09:09:40 misc_models and .ASE models j/k  "Brush Primitives"  #608 posted by Kinn on 2016/10/05 13:41:39 Wow that was quick :) Here's a test map in the Quake3 BP format: https://dl.dropboxusercontent.com/u/61424391/Quake%20Stuff/testq1q3.map I compiled it with your new build and it seems to work fine, cheers! So, here's how you set up NetRadiant to use the BP format: Edit the q1.game file located somewhere like here: "C:/NetRadiant/netradiant-custom/netradiant-custom-20160911/games/q1.game" All you have to do is set brushtypes="quake3" and maptypes="mapq3". Then in the editor, go to preferences->settings->brush and make sure the "brush primitives" checkbox is turned on. Restart the editor. Now, when you are in quake 1 mode in NetRadiant, you will be reading and writing maps in the Quake3 BP format. Everything else is still Quake 1 style - wad textures work fine and all that. I still need to pester the NetRadiant guy a bit more though. In the test map, I have included a crude terrain ceiling to illustrate the main problem with the editor's handling of the BP map format - which is ironic considering the format was created for Radiant in the first place... When in BP mode there currently seems to be no way of telling a face to use the old axial projection - it's face projection all the time. Face projection is great to avoid the weird skewed textures on certain angled surfaces that you'd get in quake's original map format, but for stuff like gentle terrain you would almost always want axial projection to get seamless texturing. The terrain in the map looks terrible because of this. But yeah I just need to pester the guy maintaining NetRadiant to add the ability to choose face or axial projection on a surface. A little bonus thing you could do that is not important, but might be worth doing, would be to read Quake3's "detail" flag on brushes, as an alternative to using func_detail - this might come in handy for people who want to try converting existing Quake 3 maps over to Quake.  _shadow Bug?  #609 posted by Qmaster on 2016/10/06 06:34:54 Hmm...not sure this is a bug or not, jpegs below: Func_wall no _shadow: computer_noshadow Func_wall with _shadow 1: computer_shadow1 See the hard line where the face changes textures at the trim baseboard?

So the wall behind would need to be cut to shape around the computer panel rather than having them simply overlap. Try it and see if it helps, I guess.  Qmaster  #612 posted by ericw on 2016/10/06 08:13:36 I think that bug was fixed in v0.15.7 :) If you're on an older version, updating to the latest should fix it.  Feature Idea / Request  #613 posted by Shamblernaut on 2016/10/06 17:19:37 So I was messing about with flashing lights and realised that due to limitations of the engine there are certain things I can't do that are pretty simple. Things like having alternating flashing lights (without needing extra trigger/relay entities). Or having a light that has a fade and a flash sequence. So I was thinking about custom lightstyles. Here is the idea: A light entity with the tag "_lightstyle" which allows users to have cusom "id" format lightstyles: string value a-z (example: "aallzzll"). What are your thoughts?    #614 posted by metlslime on 2016/10/06 19:24:06 I think something like that could be done in quakec.  Absolutely Metl  #615 posted by Shamblernaut on 2016/10/06 19:31:54 but that won't apply to vanilla or to AD or quoth, etc.  Shambernaut  #616 posted by Kinn on 2016/10/06 19:35:57 read that as "can only be done in quakec"  Lighting Question  #617 posted by damage_inc on 2016/10/07 06:58:57 Phong shading and Deviance are easy to understand as "options" you can exercise in your mapping. But I am a little confused about bounce(radiosity) and dirtmapping(AO). Bounce: From my limited knowledge IIRC radiosity lighting is superior to standard Q1 lighting, yes? And if so, would that be considered to be the default choice(standard) for mappers from now on going forward? Dirtmapping: Should this also become standard practice in lighting a map, or more still just an option for giving a certain design/artistic "look"? Thanks.    #618 posted by ＰＲＩＴＣＨＡＲＤ on 2016/10/07 07:14:50 Both options can provide a pretty significantly different look. Bounce lighting is one that I personally see as almost always desirable, with the exception that it makes it quite difficult to have stark contrasts in your lighting (which you may or may not want to have depending on specific situations) due to the fact that light will, well, bounce! I can't think of a situation where it's made a map look bad, but by no means is it necessary to use if you want your map to look good. Dirtmapping, in my mind, is a bit more subjective. It certainly helps to add a "look" to your map, although depending on how you tweak the values that can either be very intense or very minor. It's certainly not appropriate for all situations, but taken in moderation I think that it's generally useful. I think the same really goes for a lot of the modification's ericw has made; yes, they do have a distinct look that changes how the final product uses, but it's generally a tasteful, inoffensive change that most people would take as being an improvement. I mean, compared to coloured lighting (especially when ported back into older maps i.e. the original game) it's pretty harmless, and we've learned to live with the existence of that technology... Anyway, I'm not exactly prolific enough to have a "default" for my maps, since I have about... 3 to my name, none released, but so far I've always used bounce and dirt with varying settings in my creations.  Negative Lights For Stark Contrast  #619 posted by Qmaster on 2016/10/09 15:19:23 I haven't tested it in a while but I believe you can use lights with negative brightness to combat the horrors of bounce lighting (even though it saves time putting in fill lights).    #620 posted by anonymous user on 2016/10/09 19:20:27 ericw: would it be possible to compensate for lightmap seams as described in this paper? One of those "would be nice" features.    #621 posted by Rick on 2016/10/12 07:31:42 I tried 0.15.8 a bit tonight. There seems to be problems with lights inside sky brushes or something. Or maybe a problem with very low values for light? Here's one that seems to have just disappeared. BJ/MH Light http://quaketastic.com/files/screen_shots/wish13_i.jpg 0.15.8 Light http://quaketastic.com/files/screen_shots/wish13_i_2.jpg That light shining through the window is in a sky brush, but just barely. It's almost in the void. The values are light 75 delay 5 wait .02 and the range is set to 1.0 on the command line. I saw other differences, but that's the most obvious.    #622 posted by ericw on 2016/10/12 09:43:00 Thanks; I didn't realize regular light entities were supposed to pass though sky faces. Should be an easy fix.    #623 posted by Rick on 2016/10/12 15:41:06 The thing is, most of them still did. The only one I noticed that didn't was the one in those screenshots. That's why it stood out. Is it possible it got "nudged" into the void? On the good side, about 10 of the 30 or so lights it found "in solid" actually were old misplaced lights. Also to note, there was no reduction in marksurfaces using -forcegoodtree. The number actually went up a bit. Using txqbsp_xt always gives a drop of around 1200 or so.  New Version V0.15.9  #624 posted by ericw on 2016/11/21 05:47:30 Download here Changes: - light: fix black fringes on bmodels that are touching against the world - light: light passing through glass lights up the back side - light: bmodels with "_alpha" < 1 and "_shadow" "1" set cast tinted shadows - qbsp: support Quake 3 "Brush Primitives" .MAP format - qbsp: save "_mincolor" for func_detail/group to the .texinfo file, now used by light - qbsp: performance improvements To elaborate on the "fix black fringes on bmodels" thing, v0.15.8 had a pretty severe bug where every func_door (or any bmodel) would have black edges wherever it touched the world, like an ugly/broken looking version of AO. The reason I broke that in v0.15.8 was, I was trying to fix another bug, where bmodels (func_wall, etc.) that intersect the world, or have a face touching the world, would have broken lighting (usually all-black faces). Typical case where this would happen would be a large func_wall window that has a world brush slicing through it (or just touching the front). So, that bug is back, because the "fix" I tried was much worse (black fringes on all bmodels). If you have a func_wall with black faces / broken lighting, the fix is to manually clip it against the world so it doesn't stick into the world anywhere. I'll see if I can come up with a better fix next version  Fringe Of Darkness  #625 posted by mjb on 2016/11/21 12:57:59 That's great to hear, I encountered the black fringe issue before and it is good to know it may be fixed on this release!    #626 posted by ＰＲＩＴＣＨＡＲＤ on 2016/11/21 13:31:35 Would it be possible to hit both bugs by having the compiler test if the bmodel intersects or not? Or would that require multiple passes or something like that? (Assuming extra passes would suck, which when it comes to speed they probably would :/)  Qbsp  #627 posted by Qmaster on 2016/11/21 16:20:54 Performance improvements - intrigued, my latest maps have been bottlenecked by Qbsp which is wierd since vis always took the longest until recent improved versions. Curious what improvements you've made.    #628 posted by ericw on 2016/11/21 18:34:11 @Qmaster - performance improvements are from undoing some mistakes I made when C++-izing bits of qbsp (unnecessary std::map lookups). Qbsp could be made a lot faster, though. e.g. Quake 2's is multithreaded. Pritchard, I'm not sure if knowing if the bmodel intersected the world would help. I think I need to do something like: test whether each sample point is in the void or not, and just not use the ones that are in the void.  Dumb Question  #629 posted by ＰＲＩＴＣＨＡＲＤ on 2016/11/22 03:11:09 How do you do lit liquids? I tried the commandline flags people are talking about here (-litturb etc.) and it just gives an error and doesn't run light. Was it removed or something?    #630 posted by ericw on 2016/11/22 03:37:27 -splitturb option for qbsp.exe should do it; light.exe will automatically detect this and save lightmaps for the water. Looks like that option is missing from the docs. Engine support is fairly rare (?) - I don't know what supports it, off hand.    #631 posted by khreathor on 2016/11/22 12:15:47 Engine support is fairly rare (?) - I don't know what supports it, off hand. So I can "bake" lightmap on the water and it will be still fullbright in some engines, or what?    #632 posted by Kinn on 2016/11/22 12:49:05 So I can "bake" lightmap on the water and it will be still fullbright in some engines, or what? Yes. There is that one software render engine that mankrip is doing that supports it I think. That's the only one I am aware of. However, give other engine authors a slap and a tickle in the right place and I'm sure this feature can be adopted elsewhere (it bloomin well should be because it's coolbeans)    #633 posted by ItEndsWithTens on 2016/11/22 19:23:09 I just checked my Jam 7 map to be sure I was remembering correctly, and Darkplaces supports lit water too, at least version 15:49:13 May 13 2014. Incidentally, I discovered the final version of my map is apparently broken in that engine for a different reason, which is just fantastic, but the lit water works as expected. It's easier to see the effect with r_wateralpha 1, of course.  Crazy Idea  #634 posted by Kinn on 2017/01/04 23:00:03 All this talk of lightstyles in the AD thread got me thinking... Say you had a moving object with start and end positions in radically different lighting conditions. Imagine you could tell the light tool to light this object in position 1, assigning all light on it to lightstyle "x", and then light it again in position 2, assigning the light to style "y". Then in the QuakeC you could fade lightstyles x and y in and out as the object moved. Just an idea, but it struck me as interesting that this sort of cheap dynamic light effect boils down to being a compiler thing + a bit of QC. You could even go nuts and leverage the fact you can have up to 4 lightstyles on the object, so can specify up to 4 different positions to light it in, allowing much more accuracy in the blending as the object moves around. I may be missing a few "gotchas" but, does the theory sound basically correct?    #635 posted by metlslime on 2017/01/05 02:43:22 there are only 64 lightstyles total, and 32 of them are used by light.exe for switchable lights, the other 32 for "styled" lights (flickering/pulsing) -- of which about 11 are actually used in id1 progs. So I think this would work if you were willing to dedicate 2-4 styles just for that one moving object, and write a quakec modification as necessary to do the proper fading.  It Is Intriguing  #636 posted by Kinn on 2017/01/05 03:20:16 I guess it would be something that could become an attractive idea when you have situations like in Hrimfaxi's rrp map, where there is a large section of a big room that moves up through several floors. Wouldn't be worth it for run-of-the-mill platforms and what not, but for big setpiece movers I can see it having the potential to look quite sexy.    #637 posted by mankrip on 2017/01/05 03:22:38 There are 64 lightstyles, but Quake's BSP format only supports 4 different styles per surface. IMHO, a more practical solution would be to use the "Lit BSP models" feature from the Makaqu engine 1.6 (used to adjust the brightness of the ammo boxes to the ambient lighting) and add an option to make it also work on internal BSP submodels.  #637  #638 posted by Kinn on 2017/01/05 03:32:49 I only suggest the idea because it struck me as interesting that it doesn't need a custom engine. I'd be happy to use up a handful of lightstyles on a moving room setpiece. How is the "ambient lighting" determined in Makaqu?  Cool Idea!  #639 posted by ericw on 2017/01/05 03:49:22 I think the challenge is working out a standard between the mapper, light.exe, and the QC. light needs to have a copy of the logic for the func_door/train or whatever is moving. Func_door would be pretty easy, func_train would be trickier (unless the mapper marks which path_corner's to calculate lighting at, up to 4 per train?). Also, things like making sunlight/sunlight2 use a lightstyle other than the default of 0 are certainly possible without too much work in the light tool. Easiest way might be for the mapper to specify a lightstyle number with a worldpawn key like "_sunlight_style" - light would then use that for the sunlight, and know not to assign that style number for a switchable light.    #640 posted by Kinn on 2017/01/05 04:04:16 I guess one implementation could be... I would suggest light.exe should not need to know how the object moves - it only needs to know the positions to light it at - these could be specified in the map with "info_lightmodel" entities - they would mark the various positions (mins?) of the brushmodel. The info_lightmodel would target the brushmodel (to let light.exe know what to light, obviously), and also specify the "style" number to use.  Also  #641 posted by Kinn on 2017/01/05 04:12:24 your sunlight suggestion is cool. Question: what happens with bounce light coming off a surface with styled lights? Is there a bounce for each style?    #642 posted by ericw on 2017/01/05 04:27:40 Mmm - yes the info_lightmodel sounds good. Currently styled lights don't bounce at all, this was something I limited to make the first version of the code simpler, but I want to support it eventually.    #643 posted by Kinn on 2017/01/05 04:44:38 Yeah I guess bouncing styles would have a similar problem to styles on lights with 1/x or 1/x^2 falloffs: you could propagate styles to tons of surfaces everywhere and it could get out of control. I think for most styled lights, you won't really notice the lack of bounce, but if you start doing styled sunlight, then I think sunlight bounce would be noticeable and you'd expect it to change like the direct sunlight does.  Kinn  #644 posted by mankrip on 2017/01/05 17:52:08 How is the "ambient lighting" determined in Makaqu? Nearly the same as in MDL models, using R_LightPoint and the entity origin, offset by the relative model position. As for a pure QC + assets workaround... How about this: - Make one model on origin A (start), and another on origin B (end). - Set the B model to non-solid, and enlarge it by 1 unit (not 1%) on each direction. - In the QC code, make the B model follow the origin of the A model. - Implement code to fade the .alpha of the B model according to how far it is from the end position. Almost every custom engine supports .alpha, so this shouldn't be a problem unless someone really wants to target vanilla WinQuake/GLQuake.  Bmodels With _shadow 1 Lighting Problem  #645 posted by PuLSaR on 2017/01/07 18:24:52 Does light do simplified calculations on bmodels with _shadow 1? I get weird squares of shadows on solids from complex bmodels (in places, not everywhere). Splitting a big bmodel into a few smaller ones doesn't change anything. Any suggessions?    #646 posted by ericw on 2017/01/07 20:26:21 There have been problems with _shadow 1 bmodels intersecting/touching each other, or the world. The faces that are touching can have artifacts, either black fringes or solid black or other artifacts. I forget what the current status is, because I've been swapping in and out hacks to try to combat that.. but I'm working on a more correct fix. Other than that, there shouldn't be any problem with shadows from bmodels. Check your version is 0.15.9, or feel free to email me screenshot/map if it seems like a different bug.  So  #647 posted by PuLSaR on 2017/01/07 20:56:40 If the bmodel doesn't touch another solid, the problem should be gone?    #648 posted by ericw on 2017/01/07 22:23:15 Yeah, if they're not touching the problem should not occur (at least a 2 unit gap. The light sample points are 1 unit above the face, having these sample points blocked is what causes issues)  Thanks  #649 posted by PuLSaR on 2017/01/07 22:28:39 that was very helpful  Ericw  #650 posted by Shamblernaut on 2017/01/24 16:22:42 does "-bounce 1" bounce lights with negative values?  Nope  #651 posted by ericw on 2017/01/24 19:54:25 Negative lights are ignored by bounce  Hexen 2 Rotating Entities Broken  #652 posted by Bloodshot on 2017/01/25 03:08:18 The use of an origin brush for rotating entities doesn't work with -hexen2. The origin brush is visible ingame and the brush still rotates around the map origin    #653 posted by ericw on 2017/01/25 03:26:27 Yeah, there is no origin brush support at the moment. Current behaviour is (designed for Q1 hipnotic rotation): If a brush entity classname starts with "rotate_", qbsp looks at the "target" key, and searches for the targetted (point) entity. That point entity's origin becomes the origin of the brush entity. I'm not sure if that is compatible with Hexen 2 rotation?  Probably Not  #654 posted by Bloodshot on 2017/01/25 03:46:45 Hexen 2's is more like half-life, though it uses the "flags" key for how many degrees it should rotate. I think you can manually enter the origin to specify where it should rotate but that doesn't seem to work right in trenchbroom  Figured Out A Sort Of Workaround  #655 posted by Bloodshot on 2017/01/25 04:08:26 You can actually manually put the origin in, but you have to place the brush at the map origin or it ends up outside the map. Kind of a pain to light it properly but it works otherwise.    #656 posted by muk on 2017/01/25 04:54:15 lmao that sounds like an editing nightmare    #657 posted by ericw on 2017/01/25 06:23:34 Tried implementing it, download available on the github issue It might be handy for Quake too. Hope I did it right.. if there is a brush in a brush entity with the "origin" texture, the center of that brush is used as the model origin (qbsp translates the model so that point is at 0 0 0, and sets the "origin" key). Also light no longer cares about the classname starting with "rotate_", if the brush entity has an "origin" key set to something other than "0 0 0", the faces will be translated to that position during lighting (hopefully doesn't break anything?)  Im Wondering  #658 posted by sevin on 2017/01/25 19:23:47 Is there a standard for final compile settings? I assume people leave BSP and VIS parameters alone, except maybe -bsp2 for BSP? Is that something everyone uses, or only if the map somehow doesn't compile as a regular BSP? Is there any reason not to use BSP2? For light, judging by the doc page on Eric's site, I'd guess people use -extra4, -gate 1, -bounce 1, and maybe some -soft?  Final Compiles  #659 posted by ericw on 2017/01/25 19:45:56 Yeah, the main thing is to use -extra4 on light; the other tools can stay with the default settings. -gate 1 is probably fine but it's actually a faster/lower quality option than the default. -bounce 1 is something you want to use from the beginning if you are going to use it, since it'll change the entire look of the map. -soft is personal taste, it will make the final lightmap softer. Is there any reason not to use BSP2? It's best not to use the -bsp2 flag unless it's needed so the map will run on the widest range of engines (including vanilla ones). qbsp will print an error if the map exceeds limits so that it requires -bsp2.  Also  #660 posted by sevin on 2017/01/25 19:50:45 -bouncescale .8 or so? What about sunlight and dirt settings in the worldspawn?    #661 posted by ericw on 2017/01/25 20:06:08 Tougher to generalize as those are more artistic choices. The screenshots / settings on the website give some starting points, you can also check map sources for ideas.  Yeah  #662 posted by sevin on 2017/01/25 20:17:41 I did check out some of the AD maps and was surprised to find very little dirt is used. Judging by the 1000 Cuts screenies I'd expect a lot more dirt, but maybe that's because of the greyscale. Sock seems to use 96 dirt, I'd think an intermediate between 256-512 would look nice.    #663 posted by Kinn on 2017/01/25 21:10:36 Sock seems to use 96 dirt, I'd think an intermediate between 256-512 would look nice. Sock's 96 dirtdepth is not a bad value actually. A dirtdepth of 256-512 is something that works when looking at a distant shot of an otherwise fullbright map, like in the preview image on ericw's page. For a normally lit map, it means surfaces 256-512 units away will be darkening your target surface, which can just suck all the light out of interior rooms quite easily.  Kinn  #664 posted by sevin on 2017/01/26 00:20:01 I know it's probably a good value; Sock chose it. I have no Quake experience so all I have to go on are Eric's pics and various worldspawns. I need to jump in and make myself a test map.    #665 posted by ＰＲＩＴＣＨＡＲＤ on 2017/01/26 04:54:01 I prefer to set things like bounce in worldspawn and keep my compilation configuration as "universal" as possible. I just use -extra4 and -soft on my light config, and I usually use bsp2 for qbsp because what current engine doesn't support it, anyway?  Lol...  #666 posted by onetruepurple on 2017/01/26 05:01:18 Don't use bsp2 if you don't need it.  Pritchard  #667 posted by sevin on 2017/01/26 05:14:02 You can use the bounce parameters in the worldspawn? It doesn't say that on Eric's site.    #668 posted by ＰＲＩＴＣＨＡＲＤ on 2017/01/26 05:20:55 Yeah, i'm pretty sure. Also, because of otp, i'm only going to release my maps in bsp2 from now on. (Not that I release any maps...)  #665  #669 posted by muk on 2017/01/26 05:43:09 Same. I only use in my compilation setup are the ones that can ONLY go in there. Otherwise the rest go in worldspawn. Actually, speaking out loud, I need to add those to my .fgds.  Derp.

How are you doing that?  #672  #673 posted by Kinn on 2017/01/26 14:02:53 Open the .fgd with a text editor and add/edit worldspawn fields like you would with any other entity.    #674 posted by Kinn on 2017/01/26 14:06:28 You can use the bounce parameters in the worldspawn? It doesn't say that on Eric's site. Good spot. Looks like the "Worldspawn Keys" section needs updating http://ericwa.github.io/tyrutils-ericw/doc/light.html  So Then  #675 posted by sevin on 2017/01/26 14:42:50 Which fgd are you guys using? I have a quake.fgd that came with JACK and then the AD fgd.  Dirty Choices  #676 posted by sock on 2017/01/27 15:29:29 I did check out some of the AD maps Every mapper did their own thing and there are some who did not use detail brushwork or utilize lit files. Personally I compiled all my maps in AD with dirt parameters which are setup on the worldspawn so everyone can reproduce the results for themselves. Sock seems to use 96 dirt Its dangerous to take that parameter in isolation because the dirt AO system has several parameters which all play key roles in how the dirt is applied. You also need to remember the dirt parameters work with 2 other key systems, architecture and light entities! I did countless tests with the new dirt AO system and found I wanted a strong dirt in corners that worked with finer brushwork detail. I also only added dirt to strong light source (excluded from all small/ambient light sources) and excluded it from most func bmodel entities. There are many examples of different ways to setup lights and I would highly recommend anyone to look at Honey by CZG and The Hell that's coming by warrenm because both have source files included. Honey uses strong point lights with many low fill (delay5) ambient lights and THTC uses many strong fill (delay5) lights for large windows and subtle fill lights for the rest. Both systems have different advantages and both create a different atmosphere. They are both pre dirt AO options, but they are useful for understanding lighting. The final piece to the puzzle is architecture and in my AD maps I often have _dirt and _minlight parameters on bmodels and certain architecture to correct the overall dirt parameters I use. Its impossible to expect one global setting will fix all light issues and that is why I requested Eric add the ability to all map entities to switch lighting features on/off. I also recommend everyone stop using the compiler for options and use the worldspawn instead! Why you might ask? Well so that everyone can learn from your source maps and try to understand how you did things. I usually use bsp2 for qbsp As I have said to Eric, this parameter should be on the worldspawn, it is really annoying to have to keep switching stuff around for different maps. The more parameters on worldspawn the better. Which fgd are you guys using? I have a quake.fgd that came with JACK and then the AD fgd Just edit/update either file with all the extra stuff you want. You can open a FGD in a text editor and cut and paste stuff around. Jack will run an error check on the file for you when it loads up a map, so its easy to spot errors. The format is not overly complex, the AD version should have plenty of examples of how to use the 'base' function and syntax formats for entity key types.  Back To Front  #677 posted by sock on 2017/01/27 15:39:00 I also only added dirt to strong light source (excluded from all small/ambient light sources) Sorry it is the other way around, I have not checked my parameters in a long time because I just use the same setup each new map. Strong source lights = no dirt Ambient source lights = AO dirt The dirt is excluded from the strong light sources so that you get the hotness effect around lights. Remember Dirt AO will make every surface look darker and make strong lights sources feel dull. Here is some more lighting tips to think about.    #678 posted by PuLSaR on 2017/01/27 19:22:58 I also recommend everyone stop using the compiler for options and use the worldspawn instead! Why you might ask? Well so that everyone can learn from your source maps and try to understand how you did things. That's a really good point.  Also  #679 posted by Kinn on 2017/01/27 19:42:10 Having as many compile settings as possible inside the map file makes it much more portable. Imagine working on the map on different PCs (cheeky bit of lunchtime mapping at work anyone?) or on different editors, or after upgrading editors. If as many settings as possible are properties of the map file, then it should reduce the time it takes you to sync up your settings across different environments. That would be ideal anyway.    #680 posted by muk on 2017/01/27 20:06:10 It seems the only ones that ARENT worldspawn are things like -extra/-extra4, -lux, -onlyents... things that arent followed by some sort of value. is it possible to convert these to be usable as worldspawn as well?  Well... Not So Fast  #681 posted by Kinn on 2017/01/27 20:18:04 If the idea is that you find a good value and keep it for that map - no matter what sort of compile you are doing - then it's a property of the map and it should be a worldspawn value (sunlight, dirt blah blah) If it's a setting that you keep changing to do different types of compiles (e.g. fast / final / onlyents /dirtydebug etc. ), then it's not a property of the map, and thus should remain as a commandline switch    #682 posted by mh on 2017/01/27 23:02:25 Do -extra and -extra4 gamma-correct when downsampling, or is that even relevant with lightmaps? It is something which makes a huge quality difference when generating mipmaps for diffuse textures. See http://filmicgames.com/archives/327 for something of a discussion.  Thanks Sock!  #683 posted by sevin on 2017/01/28 00:32:19 I did countless tests with the new dirt AO system and found I wanted a strong dirt in corners that worked with finer brushwork detail. I also only added dirt to strong light source (excluded from all small/ambient light sources) and excluded it from most func bmodel entities. I did notice several maps in the ones I've checked out that disable dirt on some bmodels, like func_doors. Why would you do that? Is it just because they move and their lighting changes enough that they look bad? Just edit/update either file with all the extra stuff you want. I know how to edit the FGDs, I just figured there would be a "standard" stock FGD that people use, like how everyone uses Eric's compile tools now. Strong source lights = no dirt Ambient source lights = AO dirt So you sometimes apply different dirt setting per-light? I take it that's usually for indoor areas? Honey uses strong point lights with many low fill (delay5) ambient lights and THTC uses many strong fill (delay5) lights for large windows and subtle fill lights for the rest. Both systems have different advantages and both create a different atmosphere. They are both pre dirt AO options, but they are useful for understanding lighting. I come from Source multiplayer (TF2, CS) where almost all maps take place primarily outdoors, so we don't really use "phantom" fill lights much since the light_environment and indoor sourced lights take care of most of the playspace.  Dirty Buggers  #684 posted by Kinn on 2017/01/28 00:56:59 Talking of dirt, I've always felt lights should have optional dirt "falloff" controls. It struck me when playing around, that I'd want a bright light source to not apply dirt within a certain small radius, and then after this radius, ramp up until it's subject to the full dirt settings. Something like (on the light entity): _dirt_off_radius _dirt_on_radius Should be self-explanatory, but if not: From 0 to _dirt_off_radius units, no dirt. From _dirt_off_radius to _dirt_on_radius, the dirt linearly ramps from 0 to full, and after _dirt_on_radius, it's full dirt. What I currently do is use two lights in the same place: a bright light with dirt 1, and then a smaller light with dirt -1 so that it stops the immediate geometry around the light looking unrealistically dirty. The suggestion above means you can do basically the same thing but with just the one light entity.  Hmm  #685 posted by sevin on 2017/01/28 01:14:24 I'm still trying to visualize what the dirt actually looks like on point lights. It sounds like the light actually casts shadow at its outer reaches, but that doesn't make sense. I'm not at my PC or I'd make a little test.    #686 posted by Kinn on 2017/01/29 23:02:39 I'm still trying to visualize what the dirt actually looks like on point lights. It sounds like the light actually casts shadow at its outer reaches, but that doesn't make sense. I'm not at my PC or I'd make a little test. Point lights don't "cast" dirt, so to speak. Imagine lighting a level with no dirt, then dirt is applied afterwards as a second pass. This dirt is applied over the existing light, so those lights are said to have "dirt on them". For lights that have no dirt (dirt -1), I assume those lights are applied after the dirt pass, not before it, so the light can illuminate the dirty creases. Caveat: the above is a guess, only ericw can confirm whether that's actually how it's done, but I'd be surprised if it's not the case.  Kinn  #687 posted by sevin on 2017/01/29 23:14:48 That makes more sense, thanks.  Hmmm  #688 posted by Kinn on 2017/01/29 23:21:06 ericw - is my assumption correct re: 3 passes (1: dirty lights, 2: dirt pass, 3: non-dirty lights)? If so, where does bounce lighting fit into this? I assume bounce must be subject to dirt.  @kinn + Sevin  #689 posted by ericw on 2017/01/30 04:43:59 Yep, the 3 passes explanation is correct. It's implemented slightly differently, but the result is the same: each light is rendered, possibly multiplied by the dirtmap (if dirt is enabled on that light), then summed. Also, interesting idea about the dirt falloff. I don't think it'd be difficult to do. I did notice several maps in the ones I've checked out that disable dirt on some bmodels, like func_doors. Why would you do that? I'm guessing it's the same reason shadows look bad on doors; the shadow should be stationary when the door opens, but in Quake the shadow moves with the door texture.  Mh  #690 posted by ericw on 2017/01/30 05:00:16 No, there's no gamma correct downsizing, that's something to try!  Hmm  #691 posted by sevin on 2017/01/30 05:09:15 I'm guessing it's the same reason shadows look bad on doors; the shadow should be stationary when the door opens, but in Quake the shadow moves with the door texture. So it's just to lessen the effect? Disable the dirt so the moving shadow is less noticeable?    #692 posted by Kinn on 2017/01/30 15:00:07 Also, interesting idea about the dirt falloff. I don't think it'd be difficult to do. For me, that would be really lovely as it would cleanly preserve the 1/x^2 falloff characteristics of my point lights, whilst also giving me precise distance control over when the dirt kicks in, as well as simplifying the whole setup.  Isn't It About Time For A New Map Standard?  #693 posted by FifthElephant on 2017/01/30 17:01:05 I feel like the introduction of all these new features etc is being held back a huge amount.  Fifth  #694 posted by Kinn on 2017/01/30 17:10:46 What new map spec do you have in mind?  Something With Surface Flags For A Start  #695 posted by FifthElephant on 2017/01/30 18:50:25   From The Rumblings Around Here  #696 posted by Shamblernaut on 2017/01/30 19:01:25 higher def light maps sound like they'd be useful  Go Map For Q3 Or UE4 Or Whatever The Hell Then  #697 posted by onetruepurple on 2017/01/30 19:10:21     #698 posted by mh on 2017/01/30 20:41:52 Higher res lightmaps have been talked about and we actually had an implementation at one point. Turns out they're one of those things that it's nice to talk about but when reality hits nobody really seems to want them. See the comment about "lit2" in the opening post of this thread, even. This is something that came up a lot when I was doing the original BSP2 design. There is a degree of conflict between what people want and what's practical to implement. One of the overriding design goals of BSP2 was that it needed to be something that people would actually use. It needed to be quick and easy to implement and with a high degree of compatibility. That's why it doesn't have all of the additional features that people might wish for. If you ask 10 different people you'll get 10 different answers, and any given 5 of those answers will probably be incompatible with the other 5. So it doesn't have coloured light built-in, it doesn't have 32-bit textures, it doesn't have high-res lightmaps, it doesn't even change the .map format so you can continue using your favourite editor. Implementing it is just a handful of functions and structures and even software engines get to join the party. That's why it's been successful where previous "let's design a new map format by committee" attempts have failed. I think that I've a good idea of the kind of map/bsp format that people actually do want however, and I think it looks a little like Q2 BSP but with embedded textures, BSP2 extended limits and a Q3A lightgrid.  Higher Res Lightmaps  #699 posted by Kinn on 2017/01/30 21:05:39 Yes, what mh said. See here for the start of a discussion on it when it was trialed: http://www.celephais.net/board/view_thread.php?id=60967&start=382 Feedback was rather mixed. I'm in the "meh" camp. It's funny how, once you start to increase the lightmap resolution, how quickly your thoughts seem to shift to "hmm looks a bit too crisp actually, how can I make this softer?" Heh.    #700 posted by Baker on 2017/01/30 21:30:02 I'd be curious to know what Fifth is thinking about with surface flags.    #701 posted by mh on 2017/01/30 21:54:11 My experience is that people asking for a feature typically have a very specific problem right now that the feature they're asking for would solve. For example: "can I have high-res lightmaps?" - meaning: "I'm shining a light through some grating and I'm not seeing the detail I'd like in the shadows". Thing is, they can sometimes get so caught up in the specific problem they wish to solve that they forget about the knock-on effects of the feature they want. So "can I have high-res lightmaps?" turns into "everything looks like crappy hard-edged Doom 3 shadows". Fence textures were another example. I was asked could player movement be clipped by sprites, but it turned out that the problem was that sprites were being used for gratings/etc. Fence textures were an easy addition, everything works the way it should, and the end result is more generally useful. There's more mileage in asking about what you wish to solve than there is in asking about how you wish to solve it.  More Thoughts  #702 posted by FifthElephant on 2017/01/30 22:21:52 It's interesting reading my post on higher res light maps. I think I would still be interested in 2x detail (4x at a push) but it would have to be surface-dependent (specific areas only). I think when I did those tests I might have just done it on all surfaces (wasnt needed). When I said surface flags that was certainly one example. Lots of features have been added to the compilers already that cover functions (_phong on groups, this is done by surface flags in Q2, same with alpha textures and scrolling surfaces). Maybe something that will allow terrain in the future and curved surfaces. I dunno, I was just riffing ideas tbh. My next mapping projects will not be grandiose ones like with ad_tfuma so I am not in the market for new toys and gizmos just yet.    #703 posted by mh on 2017/01/30 22:26:03 I don't think it would look good if a 4x surface was beside a 1x surface. Unless you set things up very carefully there would be quite a jarring effect where the surfaces meet.    #704 posted by ＰＲＩＴＣＨＡＲＤ on 2017/01/31 00:47:38 One thing that I would like to see added is a way to project textures at full resolution. I wanted to do that with my noirjam map to get a smooth, natural transition between grass and dirt but was unable to due to the low resolution lightmaps. I agree with the issues that high-resolution lightmaps raise, but better texture projection would be a nice feature to have. It would be a niche addition though, and like mh said, design by committee rarely works out...    #705 posted by Kinn on 2017/01/31 00:58:50 Sorry I can't get my head around why you'd want to fake texture blending via some kind of textured light projection. Opening up photoshop and making some transition textures would be by far the best option. If there was enough demand for proper texture blending, it would have to be an engine thing, perhaps done in a similar way to how Quake 3 does it.  @Kinn  #706 posted by ericw on 2017/01/31 01:12:06 I got _dirt_on_radius / _dirt_off_radius up and running, if you want to check it out here is a snapshot. For now the feature is only active if you set both keys, and there is no safety check that the _dirt_on_radius is larger than _dirt_off_radius. This does seem like a cool feature.. here is an (ugly) screenshot with: "_dirt_off_radius" "100" "_dirt_on_radius" "500" http://i.imgur.com/zWQAOtS.png The light is in the upper left of the screenshot, and the dirt is only really visible on the back wall to the right  @Kinn - Not Necessarily ...  #707 posted by Baker on 2017/01/31 01:18:48 Blend it manually! tool screenshot results screenshot I never knew I turned that into a tool, but a month ago I noticed someone talking about that tool. I guess Spirit saved off a copy.  Ericw  #708 posted by Kinn on 2017/01/31 01:54:52 Wow :) Thanks, that was fast! I've had a play with it and it makes a big difference - that will practically cut in half the number of lights I need. It looks great - torches in corners and alcoves now look correct, and the dirt nicely fades in as the light diminishes. A great addition imo :)  @kinn  #709 posted by ＰＲＩＴＣＨＡＲＤ on 2017/01/31 02:30:14 I've never had much success with tools designed to blend textures; in general, my experience with working with .wad files has been pretty awful. So far the only hassle-free, bug free experience I have had has been with (our lord and saviour) ericw's defullbright tool, which actually does what it says on the tin without refusing to load half the formats it "supports" or failing to save changes properly... Quake Texture Tool is nice, but in my experience it mangles the colours from time to time. I had to get some blended textures for my current map made by hand because everything QTT produced wouldn't match up when put next to either source texture. In any case, projecting/blending textures is a much simpler, less painful experience that can easily be achieved with a map editor and the requisite format support. If it worked like it currently does, all you'd need to know is the names of the texture you want and how to set up a spotlight. No messing around with buggy tools from the 90s/early 2000s and no messing around with things like GIMP or Photoshop.    #710 posted by Kinn on 2017/01/31 14:05:26 @baker - looks useful! @pritchard - sorry still not seeing it - leaving aside the issues associated with having an uber-high-res lightmap, you're still just projecting coloured light - it will just glow, like a stained glass window effect surely?    #711 posted by ＰＲＩＴＣＨＡＲＤ on 2017/01/31 14:27:25 Why would it glow? If you're projecting a texture, not a light, you're not projecting coloured light. Perhaps that's how it works now? To be honest I just miss being able to paint textures in Cube 2. As far as I know that was done through some kind of "map" of the level, but I don't know the specifics of how it worked. But if you're familiar with that, that's the sort of functionality I'd like to have. Probably a pipe dream...    #712 posted by onetruepurple on 2017/01/31 14:35:54 In any case, projecting/blending textures is a much simpler, less painful experience that can easily be achieved with a map editor and the requisite format support.

Perhaps that's how it works now? When you project a texture with a spotlight, you are adding positive light to the lightmap. Let's say you project a green grass texture onto some gravel - all that will happen is you are adding some greenish light to the gravel texture - you'll see the gravel texture brightened up a bit and tinted green    #714 posted by mh on 2017/01/31 14:57:11 You can project a texture and set up any blend func you wish. Do it before lighting, do it after lighting, whatever. Just because it's commonly used for spotlights doesn't mean it can only be used for spotlights. So project a green grass texture onto gravel and set up the blend as GL_ZERO, GL_SRC_COLOR and you get a straightup modulation of grass and gravel. Set it up as GL_ONE, GL_ONE and you add grass to gravel. Set it up as GL_ONE, GL_ONE_MINUS_SRC_ALPHA and set up the alpha channel of the grass texture and you get a masked overlay - kinda like Quake's sky.  Mh  #715 posted by Kinn on 2017/01/31 15:12:10 All my comments are assuming we're just using the existing system but with just a higher-res lightmap.  EricW, Baker, Spike And Other Engine Devs  #716 posted by Shamblernaut on 2017/01/31 16:33:17 So it seems obvious to me that the people who work most on the engines should drive any changes they want to see / would see to be beneficial to the community. So Baker / EricW / Spike... What would you want to see in any future map format? Regarding the screenshots from the upscaled lightmap experiment. The jaggies were gone, which was nice... But the sharp shadow edges were a bit much. It seems that some quantity of blending is nice.    #717 posted by onetruepurple on 2017/01/31 16:59:26 The "jaggies" disappear in regular resolution lightmaps when you compile light with -extra4.    #718 posted by Shamblernaut on 2017/01/31 17:35:11 Lately I've been learning lots of simple shit that I should already know.

Posting in this thread because it seems to be something to do with the compile. AD mod - create a misc_textbook and just put (for example) "\\bTest Message\\b\\n\\n" in the "message" field, and "\\bTest Message 2\\b" in the "message2" field (without quotes). If you do an -onlyents compile, the \\b gold lettering breaks and you see the backslash character in the text. If you do a normal compile, then the gold lettering appears properly. Does this happen to anyone else or is it just me?  Erm  #723 posted by gland on 2017/02/06 02:17:47 This board treats backslashes different when you preview a post versus actually posting. In my above post, please ignore the double-backslashes. They are supposed to be single-backslashes (so in my example above I am actually typing single-backslash-b etc. in the message field in the quake editor. How confusing is that!    #724 posted by ericw on 2017/02/06 02:19:56 Try doing an onlyents light compile (after the qbsp -onlyents); I think that'll fix it. the \b handling is in done in light.exe for some reason; it probably should be moved to qbsp.  Thanks!  #725 posted by gland on 2017/02/06 02:27:50 That did the trick :)  Strange Lighting  #726 posted by ＰＲＩＴＣＨＡＲＤ on 2017/02/20 14:05:00 http://i.imgur.com/1poBXfp.png Some of my func_detail gets really dark in the middle and has obvious seams with the nearby brushes. Here's how it looks in the editor: http://i.imgur.com/y6JHK4r.png Any ideas? I can mask the effect by adding another nearby light but the seam is still visible. Changing the geometry works to fix it as well, which is what I've chosen to do.    #727 posted by ericw on 2017/02/20 19:56:28 Hmm, it's tough to say. It could be a few things: - try a light compile with "-phongdebug" and set "r_lightmap 1" in engine. - try adding "-novisapprox" to light. This disables some light culling that can be over-aggressive and can cause artifacts like this, although it shouldn't be messing up in this case.  Pritchard  #728 posted by FifthElephant on 2017/02/21 00:32:11 I'd also say your geometry is overly complex on the floor. You're more likely to get lighting errors and such when the detail is so high. I'd also say high detail on the floor is not always desirable because of Quakes quirky physics.    #729 posted by ＰＲＩＴＣＨＡＲＤ on 2017/02/21 00:53:22 In my experience with the floor so far it's has worked out well, but I could easily change from func_detail to func_illusionary and use flat clip brushes for movement if it becomes a problem. I'll try your suggestions soon Eric.  I Wouldnt Do That Tbh  #730 posted by FifthElephant on 2017/02/21 00:55:18 as you may encounter similar lighting issues etc. Just keep it clean and simple, Quake doesnt need to be super high poly :)  >:-(  #731 posted by ＰＲＩＴＣＨＡＲＤ on 2017/02/21 01:02:41 I like me some polygons, dangit! I'm well aware of the func_illusionary lighting problems, but they all have workarounds and should be minimal in the first place considering my minimal amount of brush overlap.    #732 posted by ＰＲＩＴＣＨＡＲＤ on 2017/02/25 05:56:38 Was fence texture raytracing ever re-added? It'd be nice to have, my current map uses such textures quite a bit.  Yep  #733 posted by ericw on 2017/02/25 06:04:15 It's in v0.15.9. It should work automatically (the old version needed a -fence command line flag, which is no longer needed)    #734 posted by ＰＲＩＴＣＨＡＲＤ on 2017/02/25 10:53:32 Is it supposed to be reported in this line if it is acting? Embree_TraceInit: 0 skyfaces 40734 solidfaces 0 fencefaces 0 selfshadowfaces 0 skipwindings I'm noticing that there are no "fencefaces" reported, which makes me wonder if it is actually working.    #735 posted by ericw on 2017/02/25 17:33:16 Yeah, it should list >0 "fencefaces" there. Check that "_shadow" "1" is set on the entity (assuming the fence texture is used in a func_?)    #736 posted by mankrip on 2017/02/26 20:16:03 Now that more people are trying to implement lit liquids, and Darkplaces already supports it, can you turn -splitturb on by default in the BSP compiler? It has literally zero negative side effects, and the impact on performance caused by the subdivision should be negligible in any engine nowadays. It's nice that the compiler is already capable of compiling lit liquids, but no one is using this option yet. All of those new maps being released in the last months could have looked a lot better with lit liquids.    #737 posted by mh on 2017/02/26 20:48:21 I'd like to see this happen too. I think there are still a few decisions to be shaken out regarding lit water, but we're not going to get a useful discussion until a sufficient number of people have had a chance to see what it actually does look like, what all the weird corner cases are, and how it interacts with existing content.    #738 posted by ericw on 2017/02/26 21:26:47 I'm not sure about enabling -splitturb in these tools by default; I don't want to push it on mappers retroactively, which is what would happen if people upgrade tools and don't test their maps in DarkPlaces. In the longer run I think it'll be a feature like skyboxes (or phong shading, bounce lighting, etc) where mappers might use it if they're going for a modern look, and not use it if they're going for a retro look. But I agree the community in general needs to see this in action to evaluate it; DarkPlaces isn't that useful for evaluating the look because the water surfaces doesn't do the swirl effect. I have only seen it in DP and it looks OK but tends to make water look a bit like a solid wall.. I think the warping will help counteract this (as well as careful setup of wateralpha / minlight on the water brushes, from the mapper). We need a Fitzquake style engine with it. I meant to make a patch to Quakespasm for it some time, at least for making test builds to post here.    #739 posted by mankrip on 2017/02/26 21:41:27 Does Darkplaces have a cvar to disable it? If a map doesn't look good with it, the user can disable the effect. It's about having options. If lit water isn't compiled into the map, the users have no option.  BTW  #740 posted by mankrip on 2017/02/26 21:51:44 DarkPlaces [...] doesn't do the swirl effect. [...] tends to make water look a bit like a solid wall.. I think the warping will help counteract this Exactly. In Retroquad it looks great because the texture swirls while the lighting doesn't.    #741 posted by mh on 2017/02/26 22:16:44 Yeah, I compiled e1m2 with lit water and noticed the "solid wall" effect too, but this was even with the turbulent effect. Another thing I noticed is that the lightmapping tends to make translucent water less noticeable; it's actually more difficult to fine-tune a good value of r_wateralpha that works well. The thing about fullbright translucent water surfaces is that they actually blend with the lighting on the solid surfaces below them. This comes back to the statement I made earlier on about translucent surfaces probably not needing to be lit at all, but yeah, it's something that people are only ever going to be able to evaluate once they see it. Having a cvar to enable/disable options is useless IMO if the cvar isn't exposed to the player somehow. Because most players won't even be aware that it exists. That's a total cop-out; people don't read readmes so you need to pick sensible defaults and unfortunately I suspect that while community judgement on lit water is going to be "it looks crap", people are so drunk on the kool-aid that we're going to end up with a set of defaults that in a years time nobody will want.    #742 posted by ＰＲＩＴＣＨＡＲＤ on 2017/02/26 22:41:13 To me the value of lit water is that even if it is a tradeoff of sorts and can have undesirable effects (I still haven't really managed to see it in action aside from screenshots, so I can't say if it makes water look like a solid surface or not), it's still better than having water that glows in the dark. That's really what it's about for me - letting mappers use water in dark areas without it looking awful and out of place. The way it is right now looks fine in places like this, but not so much in places like this. You can make it more subtle by increasing wateralpha (it's 0.6 in these screenshots), but then you lose some of that murkiness and uncertainty from the water that a mapper might want. And it doesn't solve the problem completely anyway. By the way @ericw, thanks for the hint about the _shadow key, worked a charm. Too bad my fence textures are too finely detailed and barely let any light through :(    #743 posted by mankrip on 2017/02/27 02:09:24 mh: Having a cvar to enable/disable options is useless IMO if the cvar isn't exposed to the player somehow. That's why I'm used to implementing menu options for this kind of thing. And such menu options needs cvars. Lots of engines have options to toggle colored lighting, wateralpha and so on. It's really hard to believe you haven't thought of this possibility. Anyway, even if nobody else implements it in their engines, even if nobody else compiles it in their maps, I'll just keep doing my own thing. Even if everybody else thinks it looks bad.    #744 posted by ＰＲＩＴＣＨＡＲＤ on 2017/02/27 02:51:14 I think Retroquad looks great but i also think it should be a criminal offense that I can't play it ;-;  Clip Brushes Question  #745 posted by gland on 2017/02/27 15:19:02 Let's say I have a lot of fiddly little clip brushes used to smooth over some terrain (turning the collision into steps basically, not slopes). Should the clip brushes be made func_detail, like the terrain, or should clip always be world / func_group, regardless of how detailed it is?  I Don't Know About Quake  #746 posted by sevin on 2017/02/27 15:56:29 But in Source clip brushes don't cut visibility.    #747 posted by madfox on 2017/02/27 23:33:40 I used to place small brushes in func_wall, but for vising sake it would be func_detail.  Clip Brushes  #748 posted by ericw on 2017/02/28 00:09:21 I'm pretty sure it's fine to put them in func_detail, they will behave the same as if they are in worldspawn or func_group. (Clip brushes are only included in hull1/2, and func_detail is specific to hull0, so the features shouldn't have any interaction)  Ericw  #749 posted by gland on 2017/02/28 14:12:46 Thanks very much, that all makes sense.  3 Questions  #750 posted by former_total_newbie on 2017/03/05 14:49:12 1) If I want to upgrade to the latest tyrutils-ericw (v0.15.9) on Linux 64 bit, can I just download the Linux64.zip archive, extract it and immediately use it? That's what I tried, and qbsp seems to work ok, but light gives me the error message error while loading shared libraries: libembree.so.2: cannot open shared object file: No such file or directory. There is a file called "libembree.so.2" in "tyrutils-ericw-v0.15.9-Linux/bin/", though, so I'm confused. 2) When using running light, does it matter in which order I type in the command-line options? E.g. is there a difference between light -bounce -extra4 -dirt and light -dirt -bounce -extra4? Are they both correct? Or both wrong? Do I need to give "bounce" a value? (I've tried various variations, but I find it hard to know when/if I'm doing things correctly, as I'm not sure what the in-game results are supposed to be). 3) This is not a huge problem (yet), but one brush face in a map I've been working on suddenly stopped being lit, both when running light normally and with "-dirtdebug" (which should light all faces evenly, right? That's what it's always done before when I used it). Is there a known reason for this kind of thing? Is there anything one can do to avoid it, or is it one of those mysterious things that just sometimes happens? This is using tyrutils-ericw 0.15.8 and an outdated version of TB2 beta (the reason being that when I last tried to upgrade TB2, I seemingly had to first upgrade my then freshly installed OS, or fiddle around with repository settings to get the necessary dependencies updated to the versions required for updating TB2 -- and I didn't have the time or patience to do so. At some point I will update both). I just mention this in case this might be an issue related to the editor rather than the light tool (in which case I'll just have to live with it until I update my OS and editor). Oh, and my engine is QuakeSpasm 0.92.0.    #751 posted by ericw on 2017/03/05 19:06:24 1. Looks like I messed up packaging the linux binary. If you don't mind running light manually from the terminal, try "cd"-ing into the "bin" directory and run: LD_LIBRARY_PATH=\$(pwd) ./light {options here} Otherwise, I'll fix it in the next release. 2. Order doesn't matter, except the map has to come last. There is no parameter for -bounce (there are separate flags like -bouncescale X though). Only a few commands take optional parameters (-soft can take a number like "-soft 2"). The tool should be strict if there are mistakes in the command line options, and refuse to run. For now the manual is the best reference: here, or the website front page. 3. It would just be a bug in "light". Things that have caused black faces in the past: - bmodels (func_wall, etc.) that intersect the world - regular world faces with an obstruction near the center of the face, within 1 unit of the surface. I *think* I fixed all of these for the next version, I should put up a beta or release soon. Feel free to send me your map/bsp if you want me to check it out though.  Thank You Very Much For The Response, Ericw  #752 posted by former_total_newbie on 2017/03/07 10:36:47 1. I didn't know there was an alternative to running it manually from terminal; that's what I always do. :) Anyway, I tested typing that arcane string of characters and it works, thanks! That'll tide me over till the next release. 2. Order doesn't matter Thanks for clearing that up! :) There is no parameter for -bounce the manual is the best reference I had already read through the manual and the stuff on the front page a few times, but was still a little confused. The example of the front page is -bounce -bouncescale 2 which made me think that it doesn't take any parameters. But the manual made it seem to me as if do need to specify a value ("n"): bounce n Enables 1 bounce, 0=disable even if set in worldspawn. Available as a worldspawn key. I guess I'm misinterpreting something? 3. Thanks for all of this info. The brush with the unlit face is just a regular unobstructed worldbrush, but it's good to know these things for future reference. Thank you very much for offering to look at the map. If the problem persists, I might take you up on the offer, but a lot is bound to change in the map, so the problem might resolve itself in the mean time. Plus, the file is a huge mess of provisional brushwork, newbie mistakes, textures that have not been properly aligned yet, etc., and though I know no-one but me cares, I'm still too embarrassed to share it in its current state.  Intensity Of Color Lights  #753 posted by Aelf on 2017/03/13 04:43:23 Hi, I noticed that color lights have different intensity than the neutral ones. https://flic.kr/p/SQKPAU In the picture all the lights have the "light" key of 150, but the attenuation and the intensity is very different. If that's "a feature", what can I do to make them look more uniform?  Aelf  #754 posted by Kinn on 2017/03/13 04:49:57 That looks like a custom engine screw-up. What engine are you using?    #755 posted by Rick on 2017/03/13 04:56:56 When you change the color, it reduces the intensity of the colors that you don't want. If a white light has RGB color of 1, 1, 1 and you make it pure blue, the color becomes 0, 0, 1. You could reduce the brightness 1/2 by making the color 0.5, 0.5, 0.5 I don't think the light program compensates for this and maybe it's what you are seeing.  Rick  #756 posted by Kinn on 2017/03/13 05:01:23 That's not the problem at all here. Look at the image - that's an engine thing. The light program just can't blow the lightmap brightness up like that.    #757 posted by Rick on 2017/03/13 05:10:25 Okay, you're probably right. The picture was so dark I couldn't really see anything other than the white and blue blobs, and I was too lazy to turn the gamma up.  Hmm  #758 posted by ericw on 2017/03/13 06:07:02 White and colored lights shouldn't have vastly different intensity / falloff, and if anything white will be brighter than colored as Rick was saying.. so something is wrong here. Is the "_color" key set on the white lights (the dim ones on the right)? The engine's brightness/contrast controls are blowing out the colors so it's hard to tell what's going on. Also assuming that is Darkplaces, you can view the lightmap only by entering "gl_lightmaps 1" in the console.  #755  #759 posted by mankrip on 2017/03/13 06:59:10 It's clearly amplifying the light instead of reducing. Somehow, it seems to be adding the color to the light instead of multiplying.  Ericw's Right  #760 posted by Aelf on 2017/03/13 11:44:06 It's Darkplaces. Only the color lights have "_color" key. I'm at work right now but AFAIR I didn't use any "_deviance". If anyone wants to check it, I could take more screenshots with higher brightness or should I mess with any other parameters? I'll check the same settings in FitzQuake and will let you know.  Rtlights  #761 posted by Spike on 2017/03/13 12:57:42 Use floats, ie values between 0 and 1. Values greater than 1 will either oversaturate or be divided by 255, depending on implementation (welcome to the wild west). The lighting in that screenshot actually has nothing to do with tyrlight[-ericw], because the engine you're using is basically ignoring its output and making up its own thing based on the map entities. set r_shadow_realtime_world 0 to get it to behave properly. This'll also boost framerates significantly, so a double win... ericw, how about a feature to ignore/strip certain lights so you can more easily set up rtlights without damaging static lights? maybe  Ah Yes, Darkplaces  #762 posted by Kinn on 2017/03/13 13:46:39 Loathe as I am to suggest continually adding fudges to support all the different implementations custom engines expect - on the compile side, would it make sense to always normalise 0-255 values into 0-1 values when saved to the bsp?  Fgd File Updated  #763 posted by DaZ on 2017/03/13 14:13:40 I've updated my FGD file for version v0.15.9 of Ericw tools so you can now set phong on brush models and projected textures on lights. https://dl.dropboxusercontent.com/u/33279452/quake4ericwTools.fgd Tested with J.A.C.K steam release  Thanks Daz!  #764 posted by ericw on 2017/03/13 19:59:38 Spike, ah, rtlights explains it. Hmm maybe a key to omit an entity from the bsp could be handy, although in this case the mapper could just use colors values in 0-1. I kind of hate to add hacks like scaling the "_color" values in the bsp to 0-1, although I suppose it improves compatibility with darkplaces "auto-rtlights" and should be pretty safe.  Floats Do It!  #765 posted by Aelf on 2017/03/14 01:07:24 Thank you Spike! As soon as I changed the values into floats, the light got rendered nicely. Also, when I turned off rtworld, as suggested by EricW, the rendering was pretty close to how FitzQuake does it. Although, I do have to admit it, it's a bit bland this way. If anyone wanted to check a poor presentation of the above, go to https://flic.kr/s/aHskVVmHss.  Face->numpoints > MAXEDGES (64)  #766 posted by ＰＲＩＴＣＨＡＲＤ on 2017/03/20 15:00:10 Got this error when working on my map, after I made a brush that was way too finely curved for its own good. Is there any solution other than just having rough edges? :(    #767 posted by metlslime on 2017/03/20 16:22:31 Csg Split it into several smaller brushes?    #768 posted by mh on 2017/03/21 11:18:01 More than 64 verts will crash most Quake engines, since engines also contain code that assumes that the max verts in a face is 64. Example: https://github.com/id-Software/Quake/blob/master/WinQuake/gl_warp.c#L148 So you definitely want to keep the tools error and correct your brush instead.    #769 posted by mankrip on 2017/03/21 12:09:17 Can't the BSP compiler split such brushes automatically?    #770 posted by ericw on 2017/03/27 02:05:27 New beta: https://github.com/ericwa/tyrutils-ericw/releases/tag/ericw-v0.15.10-beta1 Has the .map conversion feature in qbsp, so you can do: qbsp.exe -convert valve mymap.map and it will write out a copy of the map in Valve 220 format to mymap-valve.map. It can also convert to "quake", "quake2", "bp" (quake 3 brush primitives). I labelled it "beta" because it's not tested enough, light has a large change to how sample points are positioned.

It's causing a lot of "too many lightstyles" warnings on my map. In more positive news, converting my map seems to have gone off without a hitch! :D    #774 posted by ericw on 2017/03/27 19:51:46 So it's the black artifacts around the floor tiles? Was that shot with -extra4? I should be able to reproduce it. re: bounce, good point, it should be opt-in, I guess. "_bounce_styled" "1" worldspawn key? Thanks for testing and glad the .map conversion worked! It should be pretty trouble free because all the brush planes are passed through losslessly.    #775 posted by ＰＲＩＴＣＨＡＲＤ on 2017/03/28 01:52:58 No, no -extra4 or soft. I haven't been using those parameters as I test the map. If you like I can create a github issue with the .map and perhaps a compiled .bsp/.lit? I did just try splitting off the problem area into its own map but I couldn't even reproduce the exact lighting I have...    #776 posted by ericw on 2017/03/28 01:59:39 Sure, or just emailing me the .bsp + .lit is fine too. I was just trying to reproduce it now.    #777 posted by ＰＲＩＴＣＨＡＲＤ on 2017/03/28 02:51:04 Also, interesting tidbit but nothing of any real issue: Converting the map to valve format through your tools seems to have reversed the order keys are listed in for TB2. Classnames are now at the bottom rather than the top. Not the case for newly created entities of course.  Lol  #778 posted by ericw on 2017/03/28 03:23:12 thanks for noticing that, should be harmless but I'll fix it!  Question  #779 posted by Kinn on 2017/03/30 18:01:31 Can sunlight be assigned a lightstyle?

Man that could open up some interesting visuals.    #782 posted by Kinn on 2017/03/30 21:47:00 It's really easy to add though, i'll add it after fixing Pritchard's issue. Cool! Sounds like a good addition Man that could open up some interesting visuals. Random dipping of light from clouds in an overcast sky...the strange pulsing of an alien sun...a simplistic day/night cycle (obvs no moving shadows but whatevs, it's not as if you can animate the skybox)... You could sync up the light variation with some variation in the fog and skyfog settings to sell the effect better. I did think it might be interesting if it was possible to have multiple different sunlight setups, all on a unique lightstyle (well you'd be limited to 3 I think) - morning, midday, evening - and you lerped their light intensities in QC (along with "night", but that wouldn't be a lightstyle, just an absence of light). But that's probably overkill and the shadows might still look odd. I'm not really sure what the performance implications are with massive amounts of lightstyled surfaces though. Are there any these days?    #783 posted by ＰＲＩＴＣＨＡＲＤ on 2017/03/31 01:57:21 I just looked up how lightstyles work, is there any limit to the length of the string? Or could you actually have a light that took a really long time to complete it's cycle? That would be a lot of letters... Also seriously? It's done with letters of the alphabet???  #783  #784 posted by Kinn on 2017/03/31 02:04:27 Yeah, you can set up those strings and have the light cycle automatically, or you can just set a single brightness value explicitly (e.g. say you wanted a slow day/night cycle thingy, I guess you'd want to set up a slow think function and increment the brightness in the think)  Clipnodes  #785 posted by negke on 2017/03/31 17:20:52 Uhm, how come this QBSP generates a whooping 11k more clipnodes than other compilers on my map?!  @negke  #786 posted by ericw on 2017/03/31 19:33:17 Hmm, I don't remember touching anything related to clipnodes since this forked from tyrutils. I just tried compiling ad_zendar.map and it looks like I can reproduce that: bjptools_xt_290914_phong2: 38011 clipnodes tyrutils-ericw_0.15.10_beta1: 44953 clipnodes So it's producing 18% more clipnodes than bjptools_xt. Is that the same kind of percent increase you're seeing / what are the total numbers of clipnodes?    #787 posted by negke on 2017/03/31 20:17:10 Around 41% in my case if my math is correct. bjptools_xt 1.2.5: 27174 clipnodes tyrultils_ericw 0.15.9: 38372 clipnodes (Also roughly 700 more marksurfaces with tyrultils)  Fun Fact  #788 posted by negke on 2017/04/02 13:57:01 Hmap2 produces an even higher count: 43601 So it's settled then: Bengt Jardrebb ftw!    #789 posted by Rick on 2017/04/02 23:10:23 I don't mind using the old txqbsp_xt in order to not exceed the standard marksurfaces limit, but I'd like to use this light. I was wondering if the problem of light not passing through sky had been fixed.    #790 posted by ericw on 2017/04/03 00:24:18 Negke thanks for the info, I'll look into optimizing the clipnodes sometime. Rick: sometimes this qbsp will produce fewer marksurfaces, so try both. About making ordinary lights go through sky faces, I tried it a while ago and I don't think it's worth the code complexity, and it caused a significant slowdown. If I added a way to add entities to specify multiple suns would that help? Alternatively just make a hollow box connecting to the window, it should only add 1 extra leaf and a few sky faces.  Beta  #791 posted by mjb on 2017/04/03 13:52:27 Tried latest beta and I receive too many light styles on faces when I didn't on the latest stable version. Going to assume that's with styles now bouncing? A few notable black faces I was keeping track of are still showing as pure black. Just reporting!    #792 posted by anonymous user on 2017/04/12 22:34:25 latest build from here has a bug. Rotate_object arent lit, leaves them all black.  Thx  #793 posted by ericw on 2017/04/12 22:51:51 i'll look into it. The git master and 0.15.10-beta1 versions of light are half-baked at the moment, I recommend the stable version 0.15.9.  Light Absorption For Deep Liquids  #794 posted by mankrip on 2017/05/08 03:24:19 When a deep lake full of mud or slime is in a very bright area, the lighting from the outside will illuminate it as if the liquid didn't exist. This is specially true for lakes under open skies with sunlight. How complicated would it be to implement an option in the light tool for underwater faces to receive gradually less light according to their distance from the water surface? I suppose it could work this way: 1) If the face is underwater, check if the light entity is not underwater; 2) If the light entity is not underwater, make a list of all liquid surfaces between it and the underwater surface; 3) For each ray, check which liquid surface in its path is closest to the light entity; 4) Calculate the distance from the liquid surface to the underwater face, and use it to reduce the brightness received by the lightmap. Note: Light entities placed underwater shouldn't be affected by this, because their underwater brightness was deliberately set by the map author. I think this feature could be very useful, specially in areas with both water and slime - the slime would look more muddy than the water, because the bottom of it would be harder to see. Maybe this could be implemented through an entity field in func_detail liquid brushes.  Hmm...  #795 posted by Qmaster on 2017/05/08 05:10:11 r_waterfalloff r_slimefalloff r_lavafalloff    #796 posted by Rick on 2017/05/08 05:53:40 But lava glows on its own. So does slime, doesn't it?    #797 posted by ＰＲＩＴＣＨＡＲＤ on 2017/05/08 07:07:13 I don't think slime necessary glows or doesn't glow, though it depends on what kind of slime it's supposed to be... In Lava's case, you'd never realistically be able to see underneath the "surface" so no one can say if it glows or not :P I feel like this effect could already be possible with negative lights - those subtract from the lightmap right? You could place a bunch of them underwater and it'd probably be possible to have the desired effect.  Light Entitys With Negative Values?  #798 posted by brassbite on 2017/05/08 07:29:15 Never knew they exist...    #799 posted by ＰＲＩＴＣＨＡＲＤ on 2017/05/08 07:43:43 I've never tried using them myself but it's in the docs.    #800 posted by Rick on 2017/05/08 14:21:20 I was thinking of Quake 2 where (all?) liquid textures had surface light. So I guess that's actually irrelevant. Quake's palette shifting effect tends to make underwater areas too bright anyway but negative light would probably still help.    #801 posted by mh on 2017/05/08 18:14:03 Attenuate faster if the trace crosses a water surface. How do you see this working with moving liquid bmodels?  MH  #802 posted by mankrip on 2017/05/08 18:53:56 How do you see this working with moving liquid bmodels? Let's follow the current standard: "_shadow" "n" If n is 1, this model will cast shadows on other models and itself (i.e. "_shadow" implies "_shadowself"). Note that this doesn�t magically give Quake dynamic lighting powers, so the shadows will not move if the model moves. Default 0. Liquid faces from inline bmodel entities should only be taken in consideration if their entity's self._shadow is 1. Shadows are, essentially, instant attenuation. Faster attenuation can be considered semi-related to shadows.  #802  #803 posted by mankrip on 2017/05/08 18:56:38   #804 posted by ericw on 2017/05/08 20:23:05 The volumetric water attenuation is certainly do-able; the raytracer is already set up to have side effects when a ray hits certain surfaces. The latest stable release from last fall has "stained glass" support, i.e. if you make bmodel with "_shadow" "1" and "_alpha" "0.5", light rays going through the entity will be partly attenuated and pick up the color of the texture. So a simplified version of water attenuation would be not considering the distance traveled underwater, but just attenuate the ray when it goes through the surface. But on the other hand, I can imagine it would look cool to have bright sunlight at the water surface fading to black (thinking of an e1m4 type environment). Anyway it's a cool idea to add to the todo list. My first priority now is fixing the breakage that Pritchard reported a while back, which I'm making good progress on but kind of a bit drained on tbh.  "Bit Drained On..."  #805 posted by Qmaster on 2017/05/08 20:44:01 That's fine, just know that what you are doing is really really great! There is no going back to the old tools now. Incidentally, is your light or qbsp multithreaded? I know vis is, which changed light to be my current bottleneck (bounce fun notwithstanding).    #806 posted by ericw on 2017/05/08 21:17:09 Thanks, appreciate it :) Light is multithreaded, qbsp is not. Qbsp could get a lot faster, it spends most of its time in CSGFaces checking if each brush intersects each other brush in the map. Quake 2's qbsp is multhreaded. The main performance tip for light is to avoid using -extra or -extra4 except on your final compile, and also add -gate 0.1 or something to reduce the overhead of delay 2 lights.  #804  #807 posted by mankrip on 2017/05/09 08:29:36 Thanks! No problem, I can wait.  Light Diff  #808 posted by mankrip on 2017/05/10 02:22:17 Idea: When a map is recompiled, compare its entities with the entities in its previously compiled BSP file, and use the radius of each light to determine which surfaces had their lighting changed. This way, when recompiling lights, the light tool can simply copy all unchanged lightmaps from the BSP file, and compile only the modified lightmaps rather than recompiling all lightmaps. Bounce lighting can make this complicated, so I'm not sure if it would be possible.    #809 posted by ＰＲＩＴＣＨＡＲＤ on 2017/05/10 02:26:18 I feel like if you're testing within each light's radius to see what brushes have changed, you're already doing a lot of the grunt work for compiling a new lightmap... It could work for a rough and messy sketch if you were willing to let a lot of edge cases slip through and accept the odd corrupted face or two, but then you invite the possibility of someone releasing a map compiled with that option turned on...    #810 posted by mankrip on 2017/05/10 02:53:46 testing within each light's radius Only for the light entities that changed. Quite often, it will be only 1 light.    #811 posted by ericw on 2017/05/10 03:13:41 What I've been thinking of, that's sort of related to that, is making a light preview tool; it would be a small GUI application with a 3d view with WASD+mouselook. You would open a map file and the tool does qbsp and light and displays the result, except the light baking is done on faces near the camera first, and the 3d view updates as each face finishes baking. Then it would refresh whenever the .map file is re-saved. I think this would be pretty sweet.    #812 posted by metlslime on 2017/05/10 06:24:56 yeah, what I have always wanted is a tool that lets me edit the lighting in realtime. I think that a diff-based approach to recalculating lightmaps would be fast enough to make this possible. Most edits would only affect one light, which has only local effects. Of course editing the sun values would not be as easily optimized.    #813 posted by ＰＲＩＴＣＨＡＲＤ on 2017/05/10 07:16:07 I'm not really sure what happens if you use old light data on a new BSP, but wouldn't it be pretty broken if you edited the brushwork around a light that hadn't changed. Say you made a ceiling, put a light on it, ran qbsp/light, then built the rest of the room and tried to patch. I don't know what that would look like but I imagine it'd be quite bad...    #814 posted by mh on 2017/05/10 21:49:16 Yeah, that would be quite broken. There are also complexities around light styles, combining lights with the same style, and packing in new lightdata/updating light offsets, which may in theory require to recalc for the entire BSP.    #815 posted by mankrip on 2017/05/11 01:45:10 Question: Does ._phong work across multiple entities when combined with ._shadow, to make multiple func_wall, func_illusionary, etc blend smoothly with the world's func_detail "entities"? Right now I'm on mobile and can't test it.    #816 posted by FifthElephant on 2017/05/11 02:53:54 Pretty certain it does mankrip    #817 posted by ericw on 2017/05/11 02:55:36 Iirc, separate func_detail / group will be blended if the _phong settings allow it. But other bmodels never blend with each other or world.  The Cursed Words...  #818 posted by ＰＲＩＴＣＨＡＲＤ on 2017/05/11 03:04:51 Having a real time lighting renderer like ericw would be really neat. If you were able to cull light calculations to the player's view (You'd have to be very generous - bouncing their view around corners to find lights that should cast but would otherwise be missed), you could potentially have an engine that displayed in the traditional quake style, while keeping the main benefits of lighting in real time like moving lights. I can already imagine a whole set of horrendous edge cases arising from this sort of thing, but it'd be a pretty neat thing to see and something that I'd hope modern computers would have the power to pull off...    #819 posted by muk on 2017/05/11 03:07:23 I have ZERO issue in paying for a light preview tool to be created.

Go for it ericw! Would make adding all the nifty features easier, such as testing phong or bouncescales.  #817  #821 posted by mankrip on 2017/05/13 01:21:26 Yeah, I've just tested, and it doesn't work: screenshot The back of the column is a func_detail with _phong 1. The front of the column is a func_wall with _phong 1 and _world 1. If _phong 1 worked on mixed entity types with _world 1, we could work around some of the BSP's planar/vertex accuracy limitations by alternating between func_detail and func_wall brushes. This would make the engine clip their planes at the rendering level, which is completely accurate and doesn't produce distortions.  #821 @mankrip  #822 posted by Spike on 2017/05/14 02:42:44 quake's lighting logic has some bias on its dotproducts that increses the amount of light on surfaces that are nearly perpendicular to lights (which is important for lights placed near said surface). You can disable the effect with _anglescale 1 (I think it is now - vanilla hardcoded it to 0.5) the '_phong' key simply calculates surface normals on a per-sample basis instead of per-surface (thus meaning its misnamed as it doesn't change the lighting formula). It affects the lighting, but not the shadows. While it would be possible to push the sample worldspace positions according to the same calculated normals, and determining shadows based upon those, such things would be quite unreliable in practice - for instance, a concave surface curve would logically push those sample positions inside the surface, which would result in all traces being obscured with the surface shadowing itself. so yeah, that's why you get sudden lighting changes on the edge of pillars - because -anglescale is biasing the light on one side while the other side is in pure shadow. if you want to try it anyway, this is the maths I use in FTE for tessellation: vec3 w = p0*bary[0]+p1*bary[1]+p2*bary[2]; vec3 t0 = w - dot(w-p0,n0)*n0; vec3 t1 = w - dot(w-p1,n1)*n1; vec3 t2 = w - dot(w-p2,n2)*n2; w = w*(1.0-factor) + factor*(bary[0]*t0+bary[1]*t1+bary[2]*t2); you should be able to shove something like that into GLM_InterpolateNormal (and convert from glsl to cpp - I already renamed stuff from glsl). You'll then need to return the smoothed position back through multiple callers to the point where its copied into the lightmap samples array. Bonus points if you can calculate the barycentric coords (read: interpolation weights) for general polygons instead of just triangles. like I say, you'll need to clamp the shadow-point to never be behind the surface to avoid the more obvious glitches. once implemented properly you'll get smoother lighting around corners (although due to the nature of traceline shadows, it'll probably still be somewhat sudden without anglescale 1).    #823 posted by ericw on 2017/05/14 19:16:13 @mankrip, smoothing between separate models is too difficult to attempt, imho, because smoothing relies on the model having been processed by QBSP. i.e. it involves walking around the mesh (exploring neighbouring faces to a vertex, and neighbouring faces to a face, etc.). If the models weren't clipped against each other, the smoothing wouldn't work. @spike in current git, I wiped out the "traceline to position sample points" thing. Instead I'm trying to use the same code as phong shading, so exploring the mesh by following connections between faces. So in a concave surface, it should work properly and give world space positions that are consistent with the interpolated normals. Only problem is, it needs some more work.. Pritchard's case in #773 was failing because of t-junctions in the bsp. I want light to work properly if qbsp didn't add t-junc vertices, so I'm making light do it (in memory only). re: GLM_InterpolateNormal, apologies for the current mess I made in the code and weird names.. I tried using the glm library a bit, then decided I didn't like it. (100 layers of indirection/ abstraction for basic vector operations, slow as hell debug builds,..) On the plus side the test suite is growing slowly.    #824 posted by mankrip on 2017/05/15 01:44:17 Is there an automated way to import the configuration from the non-Steam version? I've just bought JACK on Steam, and upon launch it didn't detect that the non-Steam version was already installed.  Dumb Me!  #825 posted by mankrip on 2017/05/15 01:46:50 Wrong thread. Wrong tab. Anyway, thanks for the explanations, ericw and Spike. I'm already going to implement something which should serve as a partial workaround, but I'll keep this info in mind for future research.    #826 posted by mh on 2017/05/15 21:34:35 Quake's dotproduct is a simple dot(L,N) * 0.5 + 0.5; i.e a rescaling from -1..1 to 0..1 (excluding the spotlight cutoff for simplicity): angle = DotProduct (incoming, l->facenormal); angle = (1.0-scalecos) + scalecos*angle; But scalecos is 0.5 (https://github.com/id-Software/Quake-Tools/blob/c0d1b91c74eb654365ac7755bc837e497caaca73/qutils/LIGHT/LIGHT.C#L13), so substituting: angle = (1.0-0.5) + 0.5*angle; And evaluate (1.0-0.5): angle = 0.5 + 0.5*angle; https://github.com/id-Software/Quake-Tools/blob/master/qutils/LIGHT/LTFACE.C#L403  Fence Volumes  #827 posted by mankrip on 2017/05/29 08:00:39 Is it possible to make brushes with fence textures be compiled in a similar way to brushes with liquid textures? By that, I mean making them become properly see-through. Currently, any brush with fence textures will clip any polygons from other brushes that touches them, which results in open holes where the other brushes should be visible. The only difference to liquid textures is that the pointcontents of fence brushes would have to be set either to solid or to empty. I guess the first case would give problems to the renderer, and the second case would give problems to the physics, but from the top of my head I'm not sure.    #828 posted by ＰＲＩＴＣＨＡＲＤ on 2017/05/29 08:49:41 I'm not sure how much interest there would be in changing how fence textures are compiled as it's already quite easy to resolve the "clipping" by making brushes using fence textures be a func_ brush such as illusionary or wall.  Lighting Artifacts  #829 posted by negke on 2017/05/29 16:15:53 Pic. What's going on there? Any way to get rid of this without anglesensing the shadows from the spikes away?    #830 posted by negke on 2017/05/29 16:24:35 Apparently it's related to the increased texture scale (2.5-3x). Jury-rebbed BJP light doesn't seem to have a problem with it (but it lacks several feature I require).    #831 posted by ericw on 2017/05/29 17:22:52 Make sure to use v0.15.9, the .10-beta1 turned out to be broken. If that's not the problem, I'm not sure from the screenshot, could I have a look at the .map (just for what's in the screenshot would be fine)?  #828  #832 posted by mankrip on 2017/05/29 21:05:09 There's a specific problem I'm having with it, when BSP entities partially inside of walls gets darker edges because part of their surfaces is in pure darkness. If such entities were part of the world, their surfaces would be clipped by the compiler and there wouldn't be any parts of them in pure darkness. But to be part of the world, they would have to be compiled similarly to liquid volumes, without clipping other brushes. Currently I can work around this by making the other brushes that touches them into func_wall entities too, but IMO this isn't the most efficient approach.    #833 posted by Spike on 2017/05/29 21:49:57 the renderer doesn't care if something's solid or not, just that its a leaf or node. same with physics, really. just make sure those fence-solid leafs don't get merged in to leaf 0 like all other solids, and that vis considers them transparent despite solid (can't say I've really looked into the vis tool itself, maybe it already goes by leaf 0 instead).  Spike  #834 posted by mankrip on 2017/05/29 22:53:33 Thanks for the explanation. The BSP tree architecture is something I've not started studying deeply yet.  Devil In The Detail  #835 posted by negke on 2017/05/30 19:20:17 I also came across an issue with detail brushes. Not sure if it's a bug or simply a technical restriction and downside of the way detail brushes are done in Quake, and also not sure if it's a general thing or only applies to certain special cases. I had a compact bit of architecure flush to the wall of a building and turned it into func_detail in order to use phong shading on it. The building's wall behind it remained solid world geometry. As it turns out, having the detail brush touch the wall like it did caused the compiler to disregard visblocking for the wall which resulted a situation where a large part of the interior was being rendered despite being completely out of view, causing wpoly to increase by 1500. Making the func_detail 'flatter' by including only the front part of the detail architecture didn't change anything; it seemed to be entirely related to the touching of detail and world brushes on that particular part of the wall. Now, this might be an edge case caused or faciliated by the shape and construction of that particular area (sloped brushes, same brushes for inside/outside etc), but still a potential risk to keep in mind, especially if remaining unnoticed until the final release of a map. If anything, this is meant to raise awareness that excessive func_detailing can be detrimental, too. Perhaps the code can be tweaked to make sure this can't happen, or maybe it something to live with due to the hacky nature of it.    #836 posted by negke on 2017/05/30 20:05:48 Some screenshots to clarify. The face is the func_detail in question. The wall below is a door, but instead of only rendering the corridor behind it (hell knight), it even draws the atrium way out sight, much of its upper and lower parts.  Func_detail  #837 posted by FifthElephant on 2017/05/31 00:01:24 isn't a catch-all. I have found in a number of my maps that I get a speed gain in compile times but not always ideal results in culling in the game.  That Face...  #838 posted by generic on 2017/05/31 00:27:53 Is so Tron.  Tyricutils Func_detail  #839 posted by Qmaster on 2017/05/31 03:35:54 Good lighting and faster vis time and same, worse PVS splitting. Source engine func_detail: Good lighting, faster vis time, and clean PVS since it treats them as func_walls. Thing is, I don't know how you would gain the benefits of true func_details (the Source way, the right way) unless the compiler turned them into info_notnulls or func_walls. Otherwise, the mod would need to support func_detail entity in its progs.dat ... Unless engine support for func_details was added. Currently the compiler de-entity-ifies them into normal brushes. But if they were kept...  #839  #840 posted by mankrip on 2017/05/31 04:21:56 What you describe about detail brushes in the Source engine sounds close to my suggestion about see-through solid volumes.    #841 posted by ＰＲＩＴＣＨＡＲＤ on 2017/05/31 05:14:29 Isn't all VIS/PVS data precompiled in quake? Why do we need to turn brushes into a specific kind of entity in order to get a desired effect? Would it not be possible for VIS to just look at a func_detail, say "I'm going to treat this as if it were a func_wall" and be done with it? How does it work currently?    #842 posted by ericw on 2017/05/31 05:53:31 Yeah, I'm going to take another stab at fixing func_detail's PVS issues. mankrip your suggestion sounds good to me, and it sounds like it'll share the same implementation. How about (assuming I can get these to work :-) - func_detail_fence - same as "func_detail" but doesn't clip away world faces, so it's usable for fence textures. Like func_wall, but doesn't use up an entity. - func_detail_illusionary - same as func_detail_fence but no collision hulls. Like func_illusionary, but doesn't use up an entity, and as a downside it would block gunfire. Not sure if this would be useful?    #843 posted by mankrip on 2017/05/31 06:19:46 That's good. func_detail_illusionary would actually be really useful to simulate crouching. The real ground would be lower, with a func_detail_illusionary ground a little above. Of course, this would affect monsters too, so its usage may be limited to small areas.  Workaround  #844 posted by negke on 2017/05/31 11:40:51 I don't care much about quicker VIS times; all I want to achieve is phong shading and occasinally minlighting on brushes without taking up additional entity/model slots. Although marksurfaces eventually forced me to turn many of them into func_wall after all. As for the issue I mentioned above, there's a workaround. As it turns out, phong and minlight also work on func_group, so making the big face a group instead of detail gets all the effects without the PVS problems. Good to know, albeit even more hax...    #845 posted by anonymous user on 2017/06/01 01:30:32 Is there a way of increasing the lightmap resolution?  Use A Bigger Texture Than Scale It Down  #846 posted by FifthElephant on 2017/06/01 02:19:15 texture scale is linked to the lightmap resolution.    #847 posted by mh on 2017/06/01 09:37:09 LIT2 (see the opening post) supports increased lightmap resolution and we all went round the block with it a few years ago. No clear community consensus formed. My own opinion is that it's a poor trade off for hugely increased file sizes, and it doesn't even look as good as you'd think owing to losing the soft edges on shadows.    #848 posted by mankrip on 2017/06/09 12:37:19 It could be useful to add a compiler/worldspawn option to set portal brush contents to CONTENTS_EMPTY, because as it is, using CONTENTS_WATER, portals can't be (partially) placed inside of slime and lava.    #849 posted by mankrip on 2017/06/09 12:39:42 By the way, Quake's episode 4 already has maps with underwater portals. So, allowing portals under slime and lava would bring more feature consistency to mappers.  Azure Agony  #850 posted by Qmaster on 2017/06/09 16:26:27 Used black for its teleport texture. I think you mean teleport. Portal is something created by vis. That's not a terrible idea but I think it would serve better as an entity field: _overridecontents 1 or something to that effect.    #851 posted by metlslime on 2017/06/09 17:34:18 Just copy the teleport texture and call one copy *lavateleport and the other one *slimeteleport in your wad file.  Oh  #852 posted by Qmaster on 2017/06/09 22:10:40 thats brilliant.  New Stuff  #853 posted by ericw on 2017/06/11 06:28:01 v0.15.10-beta2 I've been working on qbsp, and did a rewrite of func_detail to fix the vis problem. The big change is, func_detail no longer seals the map (which makes more sense anyway IMHO). No more of this! (baker's shot of a way-too-big-PVS from some spot in ad_mountain). Also, I added a bunch of func_detail variants (illusionary, wall, fence) described in more detail on the release page. Thanks for the suggestions, mankrip, and Spike a while ago. This is still bleeding edge so it's marked as a beta, and I still haven't fixed the light issue you reported Pritchard.  Func_detail  #854 posted by sevin on 2017/06/12 02:28:16 I didn't think that had ever cut vis. I know it doesn't in GoldSrc/Source. Was func_detail something third-party FGDs added to Quake?    #855 posted by ericw on 2017/06/12 03:21:57 Yeah it was something added later to the Quake tools - afaik originating in Quest. It's not that func_detail blocked vis, but certain setups would cause bogus portals (what negke is reporting in #835) resulting in bogus vis results.  YAY!  #856 posted by Qmaster on 2017/06/12 19:14:26   @ericw  #857 posted by dumptruck_ds on 2017/06/12 19:46:40 light: styled lights no longer bounce by default, set "_bouncestyled" "1" to enable. Just want to confirm this means bounce is disabled on id's lightstyles "flicker, pulse" etc.? Is that set in worldspawn or on the light entity or both?  @dumptruck_ds  #858 posted by ericw on 2017/06/12 20:05:17 Yep, it's for flicker/pulse and also lights that start off and are switched on. The "_bouncestyled" key is on worldspawn and affects all the flickering / switchable lights in the map. (The first release I did with bounce lighting didn't support having those lights bounce; now they can, but it's opt-in.)  @ericw  #859 posted by dumptruck_ds on 2017/06/12 20:08:35 great. thanks for all your hard work on these tools.    #860 posted by khreathor on 2017/06/13 01:36:34 thanks for -forceprt1 - I was always editing prt file in text editor to load it to JACK :P    #861 posted by khreathor on 2017/06/13 01:36:47 thanks for -forceprt1 - I was always editing prt file in text editor to load it to JACK :P  Why Is The Win32 Download  #862 posted by Mugwump on 2017/06/17 12:09:51 about half the size of the Linux and Win64 versions?  32 Is Half Of 64  #863 posted by DaZ on 2017/06/17 15:55:12 duh!  Oh, Ummm, Haha, Yeah...  #864 posted by Mugwump on 2017/06/17 17:26:22 I'm still running a 32-bit system, I didn't realize that doubling the bits would also double file sizes.

The main thing I would watch for is unwanted smoothing. The default _phong_angle is 89 which might be a bit high (face normals up to 89 degrees apart will get smoothed together). Check with a "-phongdebug" compile and set r_lightmaps 1 in the engine to see what is getting smoothed.  Update  #868 posted by ericw on 2017/07/30 21:52:49 downloads: https://github.com/ericwa/tyrutils-ericw/releases/tag/ericw-v0.15.10 - light: add "_shadowworldonly" bmodel key - only cast shadows on world, not other bmodels. - light: switchable bmodel shadows (requires QuakeC support, see light manual). - light: accept "_minlight" in worldspawn as an alias for "light" - light: handle degenerate faces, print out the vertex coordinates - qbsp: misc_external_map prefab system (see qbsp manual) - qbsp: don't write unused texinfo - qbsp: rewrite outside filling similar to q3map - qbsp: revert change to SubdivideFace which was increasing faces a bit (see 53743dd) - qbsp: add -expand option to dump the hull expansion to a "expanded.map", from q3map - qbsp: add -leaktest option to abort compilation when a leak is found, from qbsp3 - qbsp: fix handling of duplicate planes, which was causing id1 maps to leak - qbsp: try to get more reliable leaf content assignment (see a910dd8) - bsputil: --check: print BSP tree heights at the first few levels of the tree - bsputil: --check: check for unreferenced texinfo, vertices, planes - bsputil: --check: print number of used lightstyles - misc: travis-ci now runs qbsp on all id1 maps, the build fails if any maps leak    #869 posted by khreathor on 2017/07/30 23:30:40 Hey, thanks for this! I was using beta for a while. Awesome improvements!  Leaky  #870 posted by ＰＲＩＴＣＨＡＲＤ on 2017/07/31 10:21:10 Weren't there changes to how func_detail brushes are handled? My map's more like a sieve now... In other news, the removal of the Reload pointfile button from TB was a crime. A CRIME! There is far too much clicking involved now. Do you know if that lighting bug I reported when the beta first came out was ever fixed? It's still an open issue on Github, but flying around my map I haven't spotted anything particularly nasty (by quake lighting standards)    #871 posted by onetruepurple on 2017/07/31 12:21:34 Don't use func_detail to seal your map.  DoN'T UsE FuNc_DeTaiL TO SeAl YoUr MaP  #872 posted by ＰＲＩＴＣＨＡＲＤ on 2017/07/31 15:38:58 It was never my intention to use func_detail to seal my map. Think of it more along the lines of func_detail sealed my map, so when I ran QBSP it didn't catch the leaks and instead allowed the map to be VISed etc. Most of the map is actually func_detail. And most of it is capped off with far simpler world brushes to seal it. But I missed a good two dozen tiny corners and gaps it seems, and that wasn't revealed until now. Anyway I'm sure that's the least of my bad practices when it comes to VIS. Half of the map is in a giant box right now...  Func_detail Doesn't Seal Anymore  #873 posted by ericw on 2017/07/31 20:31:37 I know it's a disruptive change, and makes a lot of existing maps leak, but it was necessary to fix the longstanding bug with vis seeing through walls when func_detail is used. qbsp has an -omitdetail flag now which should make it easier to see the worldspawn leaks in-engine, or hide all func_detail in trenchbroom; hopefully it's not too bad to seal up the leaks. Do you know if that lighting bug I reported when the beta first came out was ever fixed? It's still an open issue on Github I think I still need to do some work on that. However, there are 2 things that will help for now: - enable phong shading on the ground - seal the map (the way I have light set up currently, it needs t-junctions in order to find neighbouring faces.)  YAY!  #874 posted by Qmaster on 2017/07/31 22:22:34 A func_ that actually behaves as a func_ now! Pritchard: ah the box trick. I used that for a section of a map once with a lot of angled brushes. Tsk tsk, pure mapping laziness. ;)  RE: Prefabs  #875 posted by megaman on 2017/08/01 10:24:54 awesome! However, why the weird behavior with the entities? Why do you not just simply move worldspawn brushes to worldspawn, and copy over all others?    #876 posted by ericw on 2017/08/01 20:34:00 Yeah, it's a bit weird.. I guess I wanted to be able to tweak keys/values per instance. So for example you can make several misc_external_map entities that get turned into func_door's, they all use the same external map file, and each one has different func_door settings like "angle" etc.  Easy  #877 posted by megaman on 2017/08/01 21:07:14 Make it optional! also, I'd assume "angle" gets rotated with the angles key.  J.A.C.K Fgd  #878 posted by DaZ on 2017/08/05 00:05:57 Updated my JACK editor fgd file for the latest release of these tools https://twitter.com/tdDaz/status/893588140560089090 CLICK THE HELP BUTTON on the entity properties window, it explains all the new stuff in detail for everything. Thx :)  @ericw  #879 posted by Baker on 2017/08/07 01:30:38 Have you considered putting the compile command line in the worldspawn of the output .bsp? Consider this scenario: 1) Someone makes a map 2) Releases the map source But the number of possible command line options is nearly infinite. The author of the map isn't going to remember. So even with the map source, no one would know how to compile the map to produce a similar result. This has proven in the past to even be a bit of a pita for even the id Software Quake map sources. /End random thought.  Baker  #880 posted by sevin on 2017/08/07 02:51:19 That sounds cool. I'd like that for Source maps too.  Started Using 0.15.10  #881 posted by Redfield on 2017/08/08 03:52:30 Thanks for your continued work on these tools ericw. I recently compiled with the new version and I did notice a slightly faster compile time for light. I didn't notice any issues on the map compared to compiling with the previous build. I posted this screen in the screenshots forum: http://imgur.com/vCdP9Ee The pillar on the right is a bottom half func_detail with _phong 1 and the upper half is func_breakable with _phong 1, but you can see a clear line where they meet. Do you recommend anything to make this look better?    #882 posted by Spike on 2017/08/08 04:09:25 try reducing the angle so that it doesn't try smoothing the lighting over the caps of the cylinders? this should normally happen if the caps are completely flat, but if they're angled even by 1 degree then the default angle cutoff will be too high.    #883 posted by ericw on 2017/08/08 04:23:08 Oh yeah, that makes more sense than my idea. I should probably lower the default angle cutoff a bit. The key for that is "_phong_angle" and default is 89. To confirm it is that, add the flag "-phongdebug" to light, and enter "r_lightmap 1" in the console (for Quakespasm).  Baker  #884 posted by ericw on 2017/08/08 04:27:02 +1 that would be handy. I recommend worldspawn keys for everything except -extra4/-extra anyway, but it would be useful to have a record of what command flags were used (could even add a key for saving the tools version, though that would bloat the bsp by a few bytes)  I Broke The Universe...  #885 posted by Redfield on 2017/08/08 04:48:04 Ok I tried ericw's methods by adding the new shadow keys, didn't see much happen as the breakable was still darker. Here is what happens with r_lightmap 1: http://imgur.com/tzeRgMp I guess you can still see the shadow here. Now these breakables are only a cosmetic part of the map so this is not crucial, and I could just make the pillar a good old detail brush. But if there is an easy way to fix this it would be awesome.  Pillar Caps  #886 posted by Redfield on 2017/08/08 04:52:20 I forgot to mention, the pillar caps are indeed angled as Spike mentioned, so if that means its something to do with the phong shading, maybe that helps to diagnose this.  Angles  #887 posted by Redfield on 2017/08/08 05:15:37 I set the phong angle on the breakable to a lower number 45 randomly, and noticed some improvement viewing from certain angles, but still darker from others. Should I also change the phong angle on the detail pillar as well, to match the angle on the breakable. What kind of decrease would you suggest?    #888 posted by ericw on 2017/08/08 05:27:35 Try adding -phongdebug to your light command line, it will compile very quickly and just give you a visualization of the phong shading. What you want it to look like (with r_lightmap 1) is the pillar caps to be solid and the curved surface of the pillar to be a smooth gradient. It might help to move the breakable to the side so you can see if the phong shading is blending around the cap edge.    #889 posted by ericw on 2017/08/08 05:29:34 Also 45 is the right value for "_phong_angle" if it's an octagonal pillar, any lower and the 8 sides of the pillar won't be smoothed together.  I Think Its Fixed!  #890 posted by Redfield on 2017/08/08 06:01:24 Ok here's what I'm seeing with phongdebug added: http://imgur.com/rOVWyNN http://imgur.com/GTlWNtQ After changing all of the breakable pieces and the detail brush pillar to _phong_angle 45 the darker shadowing is gone! http://imgur.com/yrkURID Thank you Spike and ericw. Great help and this map is looking good once again.    #891 posted by MaxED on 2017/08/09 13:00:14 Hi! I've added a "_falloff" light property. It allows to specify light diameter in map units (this decouples light brightness from light falloff).  Nice!!  #892 posted by FifthElephant on 2017/08/09 13:28:09 That's a feature I think a lot of people would want. Does brightness increase with light diameter though or does it stay the same?    #893 posted by MaxED on 2017/08/09 13:46:37 It stays the same.  Sounds Really Good  #894 posted by FifthElephant on 2017/08/09 13:56:28 I hope it gets implemented. I imagine you can make very bright spotlights on floors too with this.  @MaxED  #895 posted by dumptruck_ds on 2017/08/09 20:30:41 Agree with Fifth.

I've added arghrad-style sun setup using light entity. Allows to set most of sun properties using a light entity with "_sun" key set to 1. If the light targets an info_null entity, direction towards that entity sets sun direction. Light itself is disabled, so it can be placed anywhere in the map. Following light properties override corresponding worldspawn properties: light -> _sunlight; mangle -> _sunlight_mangle; deviance -> _sunlight_penumbra; _color -> _sunlight_color; _dirt -> _sunlight_dirt; _anglescale -> _anglescale. Here's a compiled version (x86 build, also supports "_falloff" property I've added earlier).  #897  #898 posted by dumptruck_ds on 2017/08/23 19:39:47 Cool. I will try this on the stand-alone version of my SM179 map. I was very displeased with the sunlight and didn't have time to tweak it as it was a 24hr jam.

No.  Thx Again  #900 posted by ericw on 2017/08/23 23:17:08 I merged in features, _sun and _falloff (only for delay 0/linear falloff for now)    #901 posted by MaxED on 2017/08/24 13:22:28 Will pointing this to an info_null effect the falloff? Actually, that's a neat idea for spotlights, so I've added that: Added "_spotlightautofalloff" worldspawn key. When set to 1, spotlight falloff is calculated from the distance to the targeted info_null. Ignored when "_falloff" is not 0.

I mean mapping like that seems clumsy and complicated. You won't get a visual in editor and more than likely it'll be trial and error going into the game back and forth to make sure your key settings are correct. What's the advantage, what am I missing?    #904 posted by muk on 2017/08/29 02:52:56 You can make a change to the main prefab and it carries over into all external uses of it. Copy+Paste means youd have to manually change each instance.  @damage_inc  #905 posted by dumptruck_ds on 2017/08/29 02:54:06 I am guessing but I think ericw is trying a sneaky way to get prefabs added to Trenchbroom someday. SleepWalkR has resisted adding them to the editor for his own reasons and this is a work around that could be added to any editor in theory. I assume with very little work. Again I am guessing... or day dreaming. I copy and paste just fine using TB2 but it would be nice to treat the prefab as a group without having to define it as a group. I dunno. Maybe I am just missing something here myself.  @me  #906 posted by dumptruck_ds on 2017/08/29 02:55:41 duh... what muk said: that too!!    #907 posted by ericw on 2017/08/29 03:24:00 One of the advantages of it if you're stuck with vanilla .map format is, you can rotate the prefabs at weird angles that would normally require valve map format to keep texture alignment, and the texture alignment will not get messed up. along the same lines, you can map something complex in the prefab file, keeping it on-grid, then rotate the instance off grid, then go back and make further edits to the on-grid prefab file.  Thanks Guys  #908 posted by damage_inc on 2017/08/29 03:30:25 I knew I just had to missing something. Seems it was alot of somethings!  @ericw : "_mirrorinside 1"  #909 posted by damage_inc on 2017/08/30 21:47:08 When you mentioned you added this did that means it's already in the binaries for use/download?    #910 posted by ericw on 2017/08/30 22:00:54 I didn't do a new release yet, but there are dev build binaries here that have it (click on x64 or x86, then go to the "artifacts" tab). Only gave it a quick testing but it seemed to work fine.  Oh Cool...  #911 posted by damage_inc on 2017/08/30 22:20:14 Muchas gracias :)  Ummm, Actually...  #912 posted by damage_inc on 2017/08/31 04:24:02 With DarkPlaces I have no z-fighting with "_mirrorinside 1" set, everything looks fine. But with Quakespasm there is z-fighting, from both the outside looking in and on the inside. Was I supposed to make sure the brush doesn't touch other brushes?  Hm..  #913 posted by ericw on 2017/08/31 04:34:16 I think you need to make all of the faces "skip" except for the water surface. Qbsp doesn't clip bmodel faces against the world, so that's the cause of the z-fighting. (in the past you had to use "*waterskip" as the skip texture for water brushes, or you'd get "Mixed content" errors, but with my qbsp you can just use regular "skip")  *waterskip Not Necessary??  #914 posted by Qmaster on 2017/08/31 04:41:02 Is this the same for *lavaskip?  Yep  #915 posted by ericw on 2017/08/31 04:50:59 you can just use skip  Ah, Got It.  #916 posted by damage_inc on 2017/08/31 04:56:38 But another question, hehe... sorry :( I think this is a side effect/limitation of the QCat play here, but items or brushwork inside the "water" don't have, hrmm how to say this... correct perspective? Does that make sense. They just look strange. I've seen this before but can't remember what it was.    #917 posted by ericw on 2017/08/31 05:23:33 I think it's a limitation of the QC; if you run it in an engine that has the swirl effect underwater like winquake, you don't get that with func_water, you only get the screen tint. I dunno if func_water is messing with the fov cvar or something?    #918 posted by Spike on 2017/08/31 09:07:41 more of an engine limitation in that the vanilla engine doesn't bother to check submodels for pointcontents, both in the physics+qc builtin as well as clientside too. (you also need a qbsp that doesn't claim water to be solid, along with generating inwards faces.) one of the ladders mods has something like 3 different glitches relating to said mod's ladders (breaks at certain framerates, leaves players stuck in walls, etc. so watch out for that.    #919 posted by ＰＲＩＴＣＨＡＲＤ on 2017/09/04 14:46:31 Is there any risk in using the 0.15.9 light binary with the rest of the 0.15.10 release? I've posted screenshots on the mapping help thread and github showing my reasons why. Having all the qbsp improvements from 0.15.10 would be nice, after all... especially the func_detail fixes.  It's Safe  #920 posted by ericw on 2017/09/04 19:13:58 The only problems would be stuff like: func_detail_illusionary will always cast shadows, and func_detail_wall would cause lighting issues if it's covering world geometry. I would go for it; the func_detail fix in .10 is worth using. Sorry I haven't fixed this earlier, also noticed some light seams in shib1.bsp that are probably coming from 0.15.10.

It's probably doable to bake in a model without converting it to brushes, but it would be illusionary only (doesn't stop bullets, no collision) so I'm not sure if it's worth the effort. If you want collision (player / monster / bullets) qbsp needs brushes, so you can use obj2map or something to convert to .map first (turning triangles into tetrahedrons with obj2map will probably give you a bloated / inefficient bsp, though).  Wait  #933 posted by Qmaster on 2017/09/06 23:03:07 Do I need to use func_detail_fence only? I've been using func_illusionary.  Qmaster  #934 posted by ericw on 2017/09/06 23:20:40 no, I tested it with func_illusionary. I don't know why it's not working for you, check spelling?

So my brain connected dots that weren't there :( What didn't work for me was standard func_detail and func_detail_wall hth's    #936 posted by muk on 2017/09/07 00:40:23 "but it would be illusionary only (doesn't stop bullets, no collision) so I'm not sure if it's worth the effort. " Still worth it, imo.  D'oh  #937 posted by ＰＲＩＴＣＨＡＲＤ on 2017/09/07 02:38:53 I think I figured out my shadow bug on my trees - it was the old "intersecting brush with func_illusionary" bug.

Still, having a fix for that bug would be nice...  Hang On  #938 posted by Qmaster on 2017/09/07 03:31:31 Turns out it wasn't compiling with the ericw qbsp at all in either version. I usually just hit yes whenever JACK warns me that prt wasnt made since I know my test map isn't sealed. Not sure what's up. The output says almost nothing to the compile dialogue.

I'm working on the beta build and just recently encountered a few errors when compiling that seem to have been alleviated with the use of bsp2 format. The first time unfortunately I did not record entirely but it stated something such as: Error: "...to many vertices... try compiling with bsp2..." Now this was most certainly not a leak. The map is sealed, there are no warnings of entities exposed to the void, no pointfile, etc. and using bsp2 fixes the problem. When I compile now with bsp2, the map compiles with vis and all is good. However, I cannot replicate the original error message. If I remove -bsp2 the compiler reports error: "13:C:projectstyrutils-ericwqbspsurfaces.cc:316: Q_assertv[1] & & v2 == edge->v[0] failed." Using bsp2 gets rid of this error as well and all is good. Now, I'm not sure what this error is, but the first message was a lot more useful and allowed me to fix the problem on my own, which is great. Maybe this error message should say something similar. Thanks  Backslashes Missing Sorry.  #948 posted by Redfield on 2017/09/12 04:59:35 The error reads: "13:C:\projects\tyrutils-ericw\qbsp\surfaces.cc:316: Q_assertv[1] & & v2 == edge->v[0] failed."  Redfield  #949 posted by ericw on 2017/09/17 02:58:31 The current code to detect if bsp2 is needed isn't very good.. I think those crashes just mean that the map needs the -bsp2 flag, but qbsp didn't detect it properly. Improving that is on the todo list.  V0.15.11  #950 posted by ericw on 2017/09/17 21:01:28 Mostly a bug fix update: https://github.com/ericwa/tyrutils-ericw/releases/tag/ericw-v0.15.11 - light: add "_sun" entity key to configure sunlight in an entity instead of worldspawn. More than one "_sun" entity is supported. - light: add "_falloff" light entity key to configure light falloff in map units. Only supported on linear (delay 0) lights. - light: add "_spotlightautofalloff". - light: fix light cutoff on curved surfaces - light: adjust -soft to fix regression in 0.15.10 - qbsp: add "_mirrorinside" key for mirroring the outside faces of bmodels so they are visible from inside. for func_water, or func_illusionary fences, etc. - qbsp: fix CSG issue with overlapping off grid brushes - qbsp: fix HOMs introduced in 0.15.10, which were caused by an attempt to fix leaks-through-solids in 0.15.10. To re-enable the buggy code that may fix leaks through solids but add HOMs, use "-contenthack" Thanks for everyone who reported bugs and m-x-d for the contributions to light :) Btw - I want to rename the project at some point, any suggestions? something that doesn't have my name in the title, haha.    #951 posted by Shamblernaut on 2017/09/17 23:58:56 light-ultra-mega-extended-nopay-0.15.10 or LUMEN for short    #952 posted by ＰＲＩＴＣＨＡＲＤ on 2017/09/18 00:58:33 Just call it tyrutils-0.16 to confuse everyone and annoy tyrann (if they're still alive) I'll have a look to see if the bugs are fixed for me yet, fingers crossed :) Also, what's the purpose of _sun on an entity?

I'll let you know if I run into anymore bugs.    #954 posted by ericw on 2017/09/18 01:29:50 Yeah - it's time to bump the version to 0.16 soon. I don't want to use "tyrutils" since that makes it sounds like tyrann endorses the tools, I think I have a good name idea though. I'll have a look to see if the bugs are fixed for me yet Thanks! Also, what's the purpose of _sun on an entity? And the purpose of having more than one? Just convenience, really - figuring out _sun_mangle is a pain; this way lets you target an info_null to set the sunlight vector. It doesn't enable any new features that you can't do with the worldspawn keys, currently. However, there are some things that would be easier to do with sun settings on entities, one that comes to mind is having a targetname to make them toggle-able (you could totally fade the sunlight with QC if that was implemented.) Having more than one sun entity is for when your skybox has 2 suns on it. :D  YAQC - Yet Another Quake Compiler  #955 posted by ＰＲＩＴＣＨＡＲＤ on 2017/09/18 02:05:18 Has anyone done this name yet? I've used a lot of "Yet Another X" software over the years. Other ideas: QTOOLS - already used for a few projects sadly, but not quake ones. func_compiler - ??? ericutils - because I know you mentioned not wanting to, but it's TRADITION, DAMMIT! W(X) - WQBSP, WLIGHT, WVIS etc. Another name reference but a subtle one. There have been a lot of different tool packages over the years. Most of them have been branded with their author's name, sadly. It's hard to be creative about something so clinical.    #956 posted by ItEndsWithTens on 2017/09/18 02:48:27 I can't pretend I'm an engineer or anything, but the urge to come up with cute names for things was irresistable, so I spent a few minutes doing a little research. Your toolset is aimed at letting people prepare their architectural designs for a Quake, so how about "Strand" or "Tendon"? I tried working in some reference to Tuned Mass Dampers at first, mainly because I like the phrase, but nothing catchy or meaningful was forthcoming. Maybe somebody else can run with that.    #957 posted by Qmaster on 2017/09/18 03:16:17 Tensor Prequisite Entwise  Suggestions  #958 posted by dumptruck_ds on 2017/09/18 20:34:16 ShadowLight Believe, BeLieVe or Be_Lie_Ve (Bsp, Light Vis) Quandary (because you have so many options in LIGHT utils!)  Quake Is Brown, So  #959 posted by anonymous user on 2017/09/18 21:18:54 BrownBrush (bsp) BrownEye (vis - eye, visibility, geddit?)

Plus reminds everyone who's working on it.  Question  #988 posted by mankrip on 2017/09/24 21:03:33 If a func_wall entity has skip-textured faces that goes deep inside the world's brushes, crossing multiple VIS areas, will said entity be "visible" across all those VIS areas, even though it has no faces to render in there? Maybe this is more of an engine problem.    #989 posted by ericw on 2017/09/24 22:33:34 I am guessing "yes" they will be visible. skip faces are deleted towards the end of qbsp so they're included in the model mins/maxs - I think. To optimize for this case I think the engine could build a tighter visible mins/maxs by iterating over all faces/vertices of the model.    #990 posted by ericw on 2017/09/24 22:33:34 I am guessing "yes" they will be visible. skip faces are deleted towards the end of qbsp so they're included in the model mins/maxs - I think. To optimize for this case I think the engine could build a tighter visible mins/maxs by iterating over all faces/vertices of the model.    #991 posted by Spike on 2017/09/25 01:31:44 the qbsp must(imho) calc model bounds according to the maximum of both rendered geometry as well as related collision structures. Failure to account for collisions means you'll end up missing initial collisions, resulting in entities getting stuck and unable to leave again (more than just a precision error). This is true (although perhaps rarer) even in vanilla.    #992 posted by muk on 2017/10/22 05:43:37 played with _falloff, its pretty damn handy. is support for the other delays feasible?  Cool  #993 posted by ericw on 2017/10/22 21:12:19 It should be possible to support for delay 1/2/5 as well. it would be a bit different for these because they extend forever, so maybe "_falloff" would set the distance where they hit 1/255 brightness, or something?  Shadows On The Snow...  #994 posted by Redfield on 2017/10/24 19:46:09 Using TyrUtils v0.15.11, working on my Frozen map and have encountered some strange shadows.

Aside from that all I can suggest is tweak the geometry. Unfortunately there's no easy fix on the tools side and any time I adjust this code it tends to break some maps and make others better. In general it looks like 0.15.9 was the sweet spot. I would revert to that but it can't handle faces that are partially covered, e.g. func_detail_wall.    #996 posted by Redfield on 2017/10/24 21:53:16 The map is sealed. I changed the geometry of the ground so that there was no seam between brushes near the shadow and the issue cleared up. Only the rock was a detail brush with phong, the ground wasn't. It is tricky to get rid of all these seams. If I revert to using v0.15.9 can I still use bounce lighting?    #997 posted by ericw on 2017/10/24 22:06:16 Yeah - bounce was added in 0.15.5. All the old releases are on the GitHub releases page: https://github.com/ericwa/ericw-tools/releases/tag/ericw-v0.15.9 Sorry to hear but I'll try to fix it in the next release :-/  Edit  #998 posted by Redfield on 2017/10/24 22:07:38 Looks like I can use bounce. I may go with v0.15.9 for now. Thanks.  Ran Into An Issue With Some Lights Being Removed  #999 posted by iriyap on 2017/10/30 10:32:49 Tried re-lighting the stock id1, hipnotic and rogue BSPs with -extra4 -soft. The result is, many badly lit patches sticking out from brush seams and various corners are finally gone, and the shadow edges are just so much better, see an example here. However, in hipnotic some maps lose some of their lights and become too dark. E.g. the start map loses the lighting from the two lamps in the room where you spawn, even if I run light.exe with no extra options. Any way I can fix this?  Some More Findings On This Weird Issue  #1000 posted by iriyap on 2017/10/30 12:09:38 Okay, so I ran hipnotic's start.bsp through several different versions of light.exe and the results are curious. I've tried the original TyrUtils, then BJP's enhanced tools, and then finally found the original light.exe from the official hipnotic devkit. The exact same compiler that the original developers used. Still no dice, the map loses some of its lights if re-lit. Why does this happen? Did they delete some entities from the compiled .bsp file to save on memory usage or what? Really disappointing.    #1001 posted by iriyap on 2017/10/30 13:45:29 Apart from hip1m5, hip2m6 and hip3m2, all the other hipnotic maps seem to be build with -range 1. Adding this option restores the original lighting. (The original hipnotic compiler also supports -extra, and they used it.) Sorry for wasting your time, but maybe this will be helpful to somebody coming from a Google search.  @ericw Or Other Tools Experts  #1002 posted by dumptruck_ds on 2017/11/07 18:56:59 Working on my AD Advent map. I have a specific need to have the boundaries of my map func_detail with _phong 1. So i've enclosed the map in a skybox. I know that's inefficient but I need it to be this way. So my question is: should I use skip textures on the outward facing brushes of the func_detail? Will it make any difference in compiling or more importantly, performance? I am using 0.15.9 because of some issues other have already posted about before. I ask because there are a large number of brushes in this case.    #1003 posted by ericw on 2017/11/07 19:26:25 If the outward faces of the func_detail touch the skybox, there's no need to texture them as skip because qbsp will clip them for you. The time to use skip is when the faces are not clipped away by qbsp, i.e. you can noclip over to them and see them, but if you know the player can never get to a position where they can see the face, you can mark them as skip so they are deleted from the bsp. It gives a tiny performance boost and reduces the file size / limits a little.    #1004 posted by onetruepurple on 2017/11/07 19:28:41 Will it make any difference in compiling or more importantly, performance? None whatsoever.  @ericw  #1005 posted by dumptruck_ds on 2017/11/07 21:17:31 Thanks. and @OTP in this case I am using FraQuake to make cave walls made up of hundreds of brushes. Sounds like it may be worth the effort in this instance. I'll do a log before and after and share the results.    #1006 posted by negke on 2017/11/08 10:11:29 Probably irrelvant in your particular example, but keep in mind skip isn't like caulk. It's really just an invisible texture that otherwise behaves just like a normal surface. You won't improve performance by putting skip on out-of-sight faces. More important than the texture used is how QBSP merges the surface. For instance, if you have a large even wall made up of multiple brushes, all on the same plane, you can optimize the unseen faces (provided they're not removed by QBSP in which case it doesn't matter) by giving them all the same texture and all the same offset (!) - and, depending on size of the wall, upscale the texture by 2/3/4/... This is to make QBSP merge all of them into a single surface and, if the texture scale in big enough in relation to the size of the surface, it'll generate fewer polys. Example: unlike modern compilers, back in the day QBSP wouldn't automatically optimize sky brushes, so the trick was to upscale sky textures on big outside areas or void maps in order to have each side of the sky box only be made of two polys. Otherwise it would have a lot of unncessary polys affecting the performance.  @negke  #1007 posted by dumptruck_ds on 2017/11/08 17:06:55 Here's what I am up to. Judging by ad_sepulcher I should be okay in this case as you said. But good info on BSP merging. I recall reading how Levelord scaled up black void texture on HIPDM1. Now it makes sense. https://i.imgur.com/d2TGj5Eh.jpg    #1008 posted by mh on 2017/11/08 20:24:27 Bear in mind that a lot of tricks to reduce polycount are probably more relevant to 1996 class hardware.    #1009 posted by negke on 2017/11/08 21:12:13 It may not have a big impact on performance nowadays, but there's still the old protocol/bsp limits. Granted, most people don't care much about these things anymore... I even upscale the texture on large triggers. :E Another thing that comes to mind regarding that sceenshot is that, at least by the looks of it, the amount of terrain detail may be somewhat excessive for Quake. Like, how much of it is visible to the player - is it well lit or hidden in darkness, or how clearly distinguishable while playing in the first place. Not saying you should make it a flat wall, just maybe a little less 'granular' (bigger brushes)? I think it's what they call the "the ionous dilemma".  @negke  #1010 posted by dumptruck_ds on 2017/11/08 23:57:22 You'll have to wait until Christmas to find out. Or until I get a decent screenshot. But most of this is viable to the player and in some cases lit fairly well.    #1011 posted by former_total_newbie on 2017/11/12 19:05:34 If I understand this correctly, I can enable phong shading on a single func_group and leave the rest of the map without phong shading: Phong shading is enabled on a brush entity using "_phong" "1". It can be used on func_detail or func_group However, I can't seem to do this in TrenchBroom -- when I edit the entity properties of a func_group containing worldspawn brushes, it changes the properties of all the world brushes in the map... What am I missing?    #1012 posted by ericw on 2017/11/12 19:30:37 TB groups are not the same as func_group, you want to use func_group for this.    #1013 posted by muk on 2017/11/12 19:32:37 You add it to the func_group itself NOT the brushes within the func_group. https://imgur.com/m33zl7R  Thanks, Ericw & Mukor  #1014 posted by former_total_newbie on 2017/11/12 21:35:49 TB groups are not the same as func_group Ah, I did not know this.    #1016 posted by Pelinal on 2018/11/28 16:41:53 so, how is the progress with the quake 2 lightmaps? i think this is the most waited stuff for those who wants to dabble with Quake 2 Unit mapping.    #1017 posted by anonymous user on 2018/11/29 01:58:31 Been using the bsp, vis, & light tools. I've had significant issues crop up while mapping for Hexen 2, in all the maps I've made. Occasionally, seemingly random areas become HOM's in-game. The issue is very odd. I'll make a standard brush, often just a cube, and then the area is HOM in-game. I can delete it, and the problem will go away. But if I make another similar brush in the same place, the problem re-appears. The map is sealed (it should be, since -leaktest has been used). There are no error messages in the compilers (except for "texture skip not found", although I havent used it). It can't be the new textures, because the problem occurred when I wasn't using any. And it probably isn't a port issue because it happens in all the ones I've tested. Here are two example screenshots, with views in-game and in-editor: https://imgur.com/a/K8F6CN7 The area in the second screenshot seems to have a separate issue from the first - there's no HOM from afar, only when you walk into the specific area. It can't be seen in the still, but the whole screen just stutters with that one frame while in the area. Also different is that no matter how I change & remove brushes in the area, the problem persists.  Anon  #1018 posted by dumptruck_ds on 2018/11/29 19:09:32 Have you tried snapping vertices to grid and vertices to integer on those brushes? Also I have seen this happen on brushes that intersect. Not sure if this is helpful.    #1019 posted by anonymous user on 2018/11/30 04:02:06 Unfortunately that doesn't seem to help. I was able to fix one brush's HOM by deleting a brush next to it. But neither of them intersected, both of them were snapped to the grid, and remaking the deleted brush didn't make the problem reappear. It's so random and frustrating, it feels like it must be a glitch/bug somewhere in the process.  Another Thing To Try  #1020 posted by dumptruck_ds on 2018/11/30 19:26:09 Go to an older version of the tools. Might be an issue with the version you are running.  Agree  #1021 posted by madfox on 2018/11/30 21:10:43 I overcome the same phenomenon. Not to blame the new tools, more my poor mapping skills. I have several maps I restarted after some months and experienced rare anomilies that earlier tools just lacked to cause. Sometimes an earlier version of the tools come out clear, while older ones causes homs and leaks.    #1022 posted by madfox on 2018/11/30 21:11:48 while the newer ones cause home and leaks.  Yeah Madfox Is On Point As Always  #1023 posted by Anom79 on 2018/11/30 22:30:31 http://web.archive.org/web/20160929072512/http://voidspark.net:80/projects/bjptools_xt/ these tools do a great job at compiling sub-grid/float precision verts. Maybe give them a try. Sadly the author vanished.    #1024 posted by ericw on 2018/11/30 23:10:09 If the area is already on grid there's probably not much you can do from the mapper's side (of course even off grid shouldn't break like this); if you can post an issue on github with the .map or a reduced test case that would help fix the problem. Alternatively trying older versions is a good idea. Maybe check 0.15.9 which was right before I did some major changes to qbsp (func_detail rewrite). https://github.com/ericwa/ericw-tools/releases/tag/ericw-v0.15.9 I can't promise a quick fix, I'm taking a break from working on tools right now and I have a backlog of bugs piling up, but I do intend to get back to it and try to fix things at some point.    #1025 posted by anonymous user on 2018/12/01 00:09:32 I tried some older versions and the problems persisted. Will post an issue, thanks.  Good Ol Bengt  #1026 posted by Qmaster on 2018/12/01 15:32:39 Seems like a vis issue ...just throwing this out but maybe try -fast vis? It is wierd how switching to txqbsp actually hsndles stuff better in a lot of cases of wierd geometry. You should still at least use ericw's vis and light...so much faster.    #1027 posted by Orl on 2018/12/01 19:09:34 Not wanting to start an argument over whats better, but I'll say that I have built some of the most absurd, overly detailed and off grid architecture and ericw's qbsp has never given me a weird error or HOM that wasn't specifically my fault.  Some Ideas  #1028 posted by ww on 2018/12/01 20:42:49 Random HOM like this could happen in q3 if the vis wasn't optimal, sealing or cutting sections up with hint faces could fix it. Also try increasing your engines limits; or dividing your map up so it's not rendering so much at once.  Compile Error For Qbsp  #1029 posted by TdB on 2019/01/17 21:13:41 when I qbsp-compile a(non-trivial, more than 1 room)map with a detail-brush in it, and use the cmd-switch: _forcegoodtree. I get the error message: "C:\projects\ericw-tools\qbsp\outside.cc:97: Q_assert(p->nodes[1]->planenum == -1) failed. #### Finished with exit status 1 "
