First up: swear I had the screenshots folder selected but oh well. I have had a quick look through mapping help re: nonsolid brushes but not finding this issue atm.
My brushes look like this in TB2

If i move past the vertical line here I fall through the brush

I am using Ericw's latest tools. 

Not sure but you can try downgrading to a different version of the tools first just in case. 

Are the brushes a func_ of some sort? Or plain bsp. Workarounds: clip to split them up into diferent brushes, make new brushes from scratch, make another brush inside them that is 1 unit smaller all around...or to add a clip brush around them.

Check that they DO NOT have an origin key. 

This is an annoying one. Assuming these are worldspawn brushes, it's a qbsp bug, but usually it can be worked around. Try the command in TB to snap the selected selected brushes to integer. Try turning the selected brushes into func_detail (not a direct fix, but it will cause qbsp to chop that area of the map in a different order and might randomly fix the problem) 

I'll have to give these suggestions a go but I'm half asleep atm. Will update when I do. Thanks 

QBSP really doesn't like 45 degree angle world brushes and generally does stupid things when you want to use them to close a space.

In this instance why not make the platform a func_wall to remove it from QBSP completely - I mean the whole chunk selected in red in your first image.

This won't affect the structure or visuals and will shorten the build time by a few microseconds. It might make the red armour drop through to the bottom floor though (can't remember) if so then a small lump of normal geometry inside that platform will fix the problem without making QBSP pee on the carpet. 

Hi, I'm new to this forum.

I've been having some issues, running quakespasm with qompiler/ericw (+fgd) & j.a.c.k.

I have few questions :

1. Exporting bmp 256 color 128x128 pixels from photoshop, and importing (ctrl+e) in wally, exporting quake 1 wad (the texture appear to be right in wally, but totally wrong in j.a.c.k. like if the color were inverted, or dark).
When I compile the map and run the game, the texture appear to be right.

2. When launched qompiler.bat (after un-zipping the latest compatible version of ericw, which is "0.15.10", when I click 1, 2, 3 or 4 (for the different commands in the menu) nothing happen, but I hear a "beep" coming from the cmd window.

3. When I compil a map, quakespasm.exe keep being deleted from the quake folder, for no reason.
I've tried with both "Don't run the game" disabled and enabled (this is when using j.a.c.k. for compiling).

Many thanks and brush well ! 

After 14 years making maps (in my case, mostly for Unreal), I seem to have run dry of new ideas. How do you guys come up with new layouts? Everything I try seems to go nowhere or be severely flawed (instead of severely flowed, eheh). 

1. I think what youre seeing is the difference in "gamma" between Wally, JACK, and your Quake engine. (What engine are you using?)

2. Do you have qompiler in the directory that holds the bin/doc folders for erics tools?

For your first use, youll need to make a configuration by following the on screen prompts and entering the options you wish to use. Reference the doc folder for the various options you can use in Erics tools.

3. Im not sure why qompiler would be kicking quakespasm.exe? Its only set to manipulate files directly related to the compilation process. You mention using "dont run game" which is an option in JACK during the compilation process. So perhaps we should start from step one and see if we can spot where things are going wrong.

For starters get your .map file and qompiler in a folder with the "bin" and "doc" folders from Erics tools.

Perhaps call it "Qompiler"

So the hierarchy would look like this:

Qompiler:
-bin
-doc
.map files
qompiler.bat

Run Qompiler. If you dont have a config saved youll need to choose option 1 and follow the prompts. If you havent a clue what to enter here its likely you can skip entering ANYTHING and just hit enter through the various prompts Qompiler gives you.

You can reference the files in the doc folder for information on the various arguments you can pass to Erics tools.

If you didnt have erics tools, itd tell you. if you dont have any .maps..itd tell you.

When Qompiler is done running it puts your compiled maps into a folder named "maps" and moves all the source .maps into "qompiled" 

btw, i wrote Qompiler so feel free to ask questions specific to it. 

I've had this same issue a few times recently. The ideas aren't coming or I hate what I am attempting. One suggestion I'd make is play more levels you love and try to discover what it is you enjoy about them.

Another suggestion would be to try a jam. There was a Speedmapping Jam last week and there's a 100 brush jam going on right now that has a few weeks left. Working within limitations may be a good way to snap out of a creative rut. 

Thanks for the reply, and for Qompiler.

I was pressing [1], [2], [3] and [4] instead of [N], [L], [E] & [Q].

I still have random issues, but like usual when setting a new engine, a lot of hassles comes with it. Time to handle the tools.. 

Yes, I'll do that. I've played less and less as time went by, this is probably a reason I don't spontaneously have interesting ideas anymore, I need to get back into the game to get back into the right mindset.

I'm not a fan of contests, but I did one a few years back and it was a fun experience (size limite, make a map weighing 512 Kb or less), but my method when I'm on such tight time constraint is to shift through my folder of abandoned projecs and drafts and conflate a couple half-completed levels. 

Probably has a simple workaround, but say I have a monster I want to target a trigger_counter for a door and a path_corner for a patrol. How do I do this? Only one target field in an entity.
