Ok, I have the same lighting question again. How can I make a "beam" of light coming from a fixed position? All I want is to be able to have a beam of light come from a crack in the ceiling, for instance, and to barely illuminate part of the room. I want it sort of like a corona of light, but the tutorial didn't help me any. I've seen in before in levels, so any help would be appreciated.

The protagonist is trying very, very hard to think very clearly about trying not to think about something else. Read it again.

If you mean the floodlights in Half-Life and Quake Arena, you have to make a transparent 3do and a gradient light texture.

tranpearant 3do?

but won't a player be able to walk through that and have a beam of light going through him?
