What?
Be specific.

Sorry. More specifically:
blue or orange gel being ejected from gel dropper seems able to partially pass through solid brushes and appear on the other side in unwanted areas.
Seems like there would be something to make surfaces impenetrable?

Are your solid brushes worldbrushes or func_ brushes?
Be aware of the use of translucent materials. They will allow a passing through.

They're world brushes. I don't think there are any translucents involved.
The paint seems to splatter out the joints between brushes too even though the edges are directly adjacent and therefore should be sealed.
Maybe try func_brushes in the areas involved?

Normally there shouldn't be any problem if you have non translucent worldbrushes.

well, the point is if you have a situation like this

___|___ where | and _ are 32px wide sometimes gel from the left will slip under | and end up at the other side of the wall. This is also the case for not-translucent worldbrushes! Using paint_cleansers also doesn't work for this.

I recommend using a invisible brush for gel sprayers and a vphysics clip for paint bombs, since paint bombs are actually physics entity.

Your walls are too thin. Make them at least 64 units thick.

Quote from s_tones on January 20, 2012, 12:29 pm

Still no joy. Thickened walls no good. Tried duplicating brushes in front of the existing ones and then overlaying then with trigger_paint_cleanser. No THAT really should work...but doesn't.
