Hi. After seeing Star Wars this past weekend, I'm consumed by the idea of
sci-fi modeling and effects. Call me a sucker for special effects. But
anyway, I was thinking of a laser blast. I managed to get a nice green laser
by using two emissive medias, one with a green cylindrical density and one
with a white cylindrical density slightly smaller than the green, all
contained in a CSG merge of a cylinder and two spheres. It looks pretty good
I think. I know that emmisive media doesn't really emit light, but I was
naively expecting that it's color would affect nearby objects when radiosity
is used, in the same way that a white sphere would pick up some green from a
green wall. in the global settings, media was set to "on".

Is the above the expected behavior of emitting media? if this is the
expected behavior, how would you go about faking a green light emitting from
the media? just attach a small light_source to the laser blast object with a
suitable fade power and fade distance?
