Tech preview showing the ability to load OBJ files with embedded polypainting (vertex painting) from Pixologic’s Zbrush
The scene demonstrated uses image based lighting, subsurface scattering, and soft reflections, and there are no textures used, with the exception of the IBL. Recorded on a dual Xeon E5645 (2×6 cores @ 2.4Ghz), this is for the most part in real time with only a slight edit to the video to cut the render progress.
