Denying portals on a "portalable" texture??

#1 · June 27, 2011, 1:43 pm

I am trying to make a room with some props on the wall,
the problem however is that you can shoot portals behind the props.
How can i prevent portals from popping up at those weird places, without changing the texture to something like blacktiles or metal stuff???

Put a trigger_portal_cleanser behind these props.

Or you can place a brush with invisible texture behind it or around it (as a sort of bounding box)

that wont work, you shoot through those brushes, i tried that.

Ill try the portalcleanser
Though one of the surfaces is on the floor, wont that just kill any portals that are still open when i walk over it??

Yeah i'd go with a func_noportal_volume if you want no portal there at all (not very realistic for that kind of situation) or a func_noportal_bumper if you just want the portal to bump away from the props (more realistic to just have it get bumped).

func_no_portalvolume is the better solution
