- Compositing Question

Ok, I saved out a 3D render with these passes: raw rgb, diffuse shading, specular shading, and alpha. What I want to do is place those over a background I make in AE. Problem is i can't get the background to show through. What do I have to do with the separate alpha channel I saved?

Aren't there any tutorials on this? I don't mean the basic ones that tell you how to move text, but actually peicing together passes from a 3D program..and actually getting an image.

well, is the alpha channel splited (seperate alpha footages ) or
it's in-built for each of footages?

It's just an alpha channel I saved out as a .tga file along with the others.

so when u r importing footages with alpha included, AE
automaticly ask you how would u want to handle the alpha?
ignor, alpha or something else, just select alpha matted &
it's done, by inserting the footages in the timeline. u must
see the bg through the alpha channel area.
if you could not see through, maybe there isn't any alpha channel
in your files,check with adobe photoshop one of the .TGAs
