We have several materials in several scenes that are composite materials and we are trying to render elements for the scenes. All of the materials within the composite are Vray Materials. When rendering the RGB Color pass renders fine, also the render id, and Velocity channels render fine, but the diffuse, GI, shadows, etc.... render those elements black. I could write a very long explaination for why we need the materials as composite mats, but lets just say we do. I can explain in later posts if it helps. Here are a couple of example images to help explain. Any suggestions or work arounds would be great.
