I complete my 360° Panorama (show here). Now I use it for a new 3D Visualisation. The first Try can you see here. I was not really satisfied. So I split the rendering into several passes. So I get what I want with mental Ray in one rendering: Beauty, Matte, AO, Z-Depth, shadows and reflections. First, the final version with color correction in Photoshop.
Following, the different passes used:
Z-Depth (corrected in Photoshop)
Ambient Occlusion Pass
