If we add 2 occlusion contribution maps in a render layer to extract char self occ and char cast occ on BG as passes in one render, we r not able to achieve the required output. We attain anyone of the below results based on the approach.
1. Both passes render without occ.
2. Only one pass render with Occ.
3. Meshes excluded in one of the 2 passes (like chars will not be added in the char cont occ pass) will be losing its matte and will be rendered behind remaining meshes in all passes of that layer.
Am using Maya 2013 64 bit. Is this normal that only one Occ pass will be rendered properly in a layer?
