Hi. I am developing a HL2 map in which there is a multimedia projector, similar to that seen in CS Office. I am a novice mapper, but I presume the actual projection was a func_wall? Not sure though. I can make the projection O.K., but I really want to have those specs of dust seen floating near the lens of the projector. I cant give a picture, but hopefully you'll understand what I'm trying to say.
