Is there a way to layer textures on brush/wall in radiant?  I'm trying to give a wall a normal texture and put one of the power switch chalk textures over it.  Is there a way to do this without having to create a custom texture? Thanks for the help!

use a patch

select the face of the wall using ctrl and shift

then use "faces to terrain" and put the chalk on that

Worked, thanks for always being helpful 

no problem
