Thanks, the code works well, but I've hit another problem. My light source
is already contained in a translucent object, like a lightbulb.
Unfortunately, it seems to be blocking the glow effect. Is there a way to
correct this, without making the lightbulb invisible? Thanks.
Also, is it possible to add the same kind of glow effect to objects other
than light sources?
I hope I'm not asking to many questions. Thanks for everyone's input!
Michael
