Hi all,
Quick question about glow.

I have this object with a 'beautiful' glow on.
I render only the object out with the glow and was thinking of
compositing it later with BG video footage.
But when I do that, the glow somehow ends up dark or black rays.
Something in me tells that it's a alpha premultiply problem.
Does anybody know any kind of workaround?
I am tempted to render out the video footage with the glow on but the
director wants them separate.

I remember having same kind of problem with fire particles.
Any suggestions appreciated, thanks.
Eriya
