Well ... 1st ... I was an idiot & overwrote my latest build with my earliest build.
The tex are missing because I've since removed them from my wad for sucking so bad.
I redid them & gave them new names for the newer version of the map.
The old map still wanted the ugly tex though.
Regarding the @ textures.
@ tex are simply tex that block vis, but are passable to players.
So ... you put up some @drapes in the window & vis can't see through.
You'll still be able to crawl through it though, cuz the brush won't block you.
It's an invaluable tool if you've gone mad with details in an area & need to drop the r_speeds, without compromising one of your many routes. i.e. windows ... mostly
I used them as blinds in ts_normandin to block the lower 4 windows in the courtyard.
R_speeds dropped by over 100 for each one I used.
Which is a good thing ... cuz now it's actually playable.
I have discovered something else though ...
@tex cannot be tied to a func_wall entity.
Which, more than likely, means they cannot be used in doors either.
Sad ... but ... oh well.
It was worth trying out.
Cheers !
