hi, i've made maps using the old codtools(1 and UO) but when i look at the map files from cod 4 i noticed that almost all of the chalk brushes have "decal" brushes under them, why ? what does this do ?
what is the reason for it, i normally just use one brush for a wall(chaulk) but on mp_backlot almost all of the walls/prefabs have these deacal brushes flickering below them, why are they used and what purpose do they serve? thats my question, since they are a separate brush from the wall its self do they make a difference ?
thanks for any info

Prefabricated building are covered in decals, this is what makes them look so good. Basically the reason you can see so many decal brushes is exactly this reason. You only texture one face of the brush so the untextured surfaces are normally covred by the caulk (even though they are invisible in game anyway)

Its there any tut on how to use decals? i cant seems to find out how to use them.

Cant remember where i saw it but from what i recall i think you create a simple terain patch and apply the decal texture to it.

use a decal no draw brush and texture only one side of it

I tried the no draw brush but i still get the see trough look, the terrain patch seem to work, but i dont think thats the right way to use it.

look at the tutorials for cod2 or cod1. Its still works the same the way.

Ok i got it figured out tnx
