Is it possible someway to make alpha masks or something to have things layered after rendering? I guess it should be possible to make a separate render of objects with a colored plane as a background. But I would like to layer the shadows or just have an opportunity to make a mask of them. Any thoughts would be highly apreciated. Actually it would be great to have an opportunity to render the fully layered multi-pass render (GI, shadows,diffuse, specular etc)
