alright, i got 2 problems. first of all i can't get the ladder brush to work. i've created a ladder and placed a brush with the system/ladder texture that envelopes the whole ladder. it just doesn't work. i can't climb up.
my 2nd problem is that i've created a catwalk with a brush that uses the caulk texture except the two visible faces, where i have applied the imperial/floorgrate texture. when i compile the map i can't see through.
so could anyone give advice?
