MR - GI & Reflection render - izze89 - 07-18-2015
I am having difficulty accomplishing a background GI and Reflection pass with FX 3.5.4 and Mental Ray. When I un-tick "visible to camera" on the FFX box, I only receive global illumination outside the FFX box, and reflections are gone all together.
Example HERE
I am aware that MR is a bit of a pain to get working properly. I am doing my FFX fire and smoke passes with scanline render elements. But unfortunately I have to rely on MR for a GI pass. I could render the pass with the fire visible and use my fire/smoke passes on top for color adjustment. But the render would go so much faster with the fire hidden and then I could have complete control over corrections to the background pass.
I have spent many days trying to solve this issue, and only resort to posting for help when at an absolute roadblock. Thanks for any tips.
