So I've got a scene that I'm going to be lighting. I want something with some fog, which I've sort of got working, but also with some lights that emit a beam of light, something like a flash light emitting the beam of light in a smoky room. Think the lighting in the Derelict ship in "Alien". I know how to create the fog. What I'm not sue is how to best have light "emitting" from some object that moves. Ideally a spotlight would be nice, but that converges to this single point, which is not wha
