i don't know if those two things are related.

i've seen that warning on many maps i've made and always ignored it.

vertices not aligning is more of a rounding error. what editor are you using? 

Worldcraft 3.3 

I took some screenshots of it in WC and then in game :E

Rotated prims are prone to misaligning after compiling. It's best to turn each side of the non-angular parts of the pipe into individual brushes so everything stays coplanar. 

Worked like a treat, thanks :) 

are there any programs out there that can read a q1 .mdl file and then output the frame macros so i can just copy/paste it into my code?

getting really tired doing that by hand.
bonus if it sets up the frame function macros too. :P 

Anyone got any suggestions for making a repeating trigger somewhat random in reset time?

Was thinking at the moment of a trigger via Nail trap with some platforms moving back and forward blocking it... 

have some func_trains blocking the trap 

about my earlier post about tele particle effects not appearing,

does Joequake have that -particle 5000, or similar feature? 

i think even winquake has it, so unless it was specifically removed, it should be there. 

Another newbie question :p

Is there any performance benefit to making certain objects func_walls or func_illusionary. Or do you just have to eat the huge VIS compile time? :( 

Massive benefit.

Detail stuff that doesn't define your vis areas (leafs) can and probably should be a func_ unless you hit the entity limit, although given the fact that most engines worth using have this limit raised you should be fine.

This sort of thing is difficult to explain without pictures.

Massive map != massive vis time
Bad vis blocking == massive vis time

Make sure to put in dogleg corridors, doughnut sections, remember that vis ignores vertical space, and to change fiddly detail to func.

There's loads of other tricks as well, but you'll have to google them all and pick it up through trial and error I'm afraid.

I think the longest (full) compile time I've had wasn't more than 6 hours. 

"vis ignores vertical space"

How does that work? :E 

vis doesn't care whether your area is 64 or 1024 units tall(?) 

vis ignores vertical space

i'm gonna have to post a wut? here too. ne'er heard that before. 

I thought vis treated all three dimensions the same. 

This is difficult to explain without a 3D diagram :P

Let's say there's a room that joins to a vertical tunnel, which 1024 units down has another room at 90 degrees - even though the rooms might not be visible to each other in game vis still treats them as if they are.

Another example - you've got a circular tube, hollow in the middle, without doors but it doesn't reach all the way to the roof (or sky) - everything outside it will be drawn the same, as long as it's not backfacing.

This was something from Q2, so maybe doesn't apply to Quake. 

What tool do I need to replace a BSP's textures?

I tried Wally and TexMex 

try again :P 

Invisible moving walls...

Possible? As far as I can tell movewalls need a visible object to move around, and noclip texture causes errors on compile. 

But I've never gotten it to work.

If you have a noclip brush inside a load of normal brushes (ie. they're on the outside of the func_) then the noclip will still push the player. 

I've managed to get it sort of working via extended movewalls :)
I don't need it to do too much, it's not actually pushing the player but monsters :E 

skip would work.

movewalls don't need a visible object.

clip only works if it's bounded by visible brushes (physics test box is determined by the outer extents of all visible brushes.) 

And download newskip.exe from a link provided by someone who knows where a copy is. Probably here:
http://www.quaddicted.com/tools/newskip.zip

Then run it after compiling your map, i.e.

"newskip mapname"

in a command prompt :S 

You mean Texmex can replace textures into a BSP?
Because I checked and it could only generate WADs with the new textures
