Applyin decals on *only* 1 brush

Alright, so I did search the forums and nothing revelent got my attention.

I have a problem (specifically in my map cs_metropolis) I applied
decals of grafittis on my wall and now these decals are repeating on
the displacement that forms the ground.

At first, I tried putting the decal a bit higher on the wall so it didn't interfere with the displacement, but it still shows.

I'm wondering though, how can this be? I've had it happen on other displacements as well, and I haven't sewn them or anything :S

Any reason you aren't using overlays (haven't done any cs:s maps, so
thought I'd ask)? Or by "decals" do you mean overlays?

info decals are good to use with simple decals that dont need to be perices.

use your overlay tool for decals you need to place on one or two brushes only.

Hm, I see. Thanks for the insight!
