I have a scene where I use mia material x shaders. It's a simple groundplane and an object. Now I want to render the scene in two seperate pieces, background and the object. The object layer should carry the shadows and reflections on the ground...how can I do that. I could set that up in maya with no problems but mia and mr...no idea. The scene has raytraced shadows and FG enabled. So it's not possilbe to just remove the ground because it reflects some light.
this is the simple way...abolutely perfect would be to have the fron, back, shadows and reflections in seperate layers. but for the start let's keep it simple
any help is greatly appreciated
