carl, you're talking about volumetric lighting effects, and there are several
ways to do this. If the file is still there, I uploaded a demo scene to
tomahawk once, with something to this effect in there, called Orion.lzh ..
in any case, this is a long subject and can be more fully covered in a LWPro
article.. anyone wanna read something like this, I'll write something if
there's enough interest...!
