That sounds promising, I'll read about that tonight thanks.

How is this different than just making a bunch of render layers, I'm quite confused by layers vs passes, they seem like the same thing?

Lamont

I dunno, set it to black hole in the properties and use that alpha to bring the object back in?

Give the object the background material, render your frame without it, then bring it back? Use that empty space as the alpha?

Yeah that's what I've been doing with render layers, kind of hassle though. I wish I could mask stuff right in maya.
