Where you are looking at now is a single wall with a normal texture. This room only contains RED lights.
Looks a bit nice doesn't it
looks a bit like the beam shader (karith, only that one is red)
Only the problem is, is that I didn't use that shader. Nor does this appear in GktGradiant (1.5), this only appears in tremulous.
Anybody know how this happens? Or more importantly, how to fix this?
