View Full Version : Mental Ray Approximation Editor Help

Hi everyone, im having some issues rendering out my displacement map in maya using mental ray, im using the mental ray approximation editor and for my displacement approximation i am using spatial, min subdivs at 3 and max at 7, same goes for the subdivision approximation. When it renders out it has a nice render time of about 2 minutes but it only generates 2 million polys, my displacement count in zbrush was at 4 million. when i raise my subdivisions to just 4 and 7 it jumps like crazy to 3 hrs of render time and overshoots generating 400 million polys,but gives an exact render of how it had looked in zbrush. i was wondering if anybody knew some other settings that would allow me to generate somehwere close to 4 million polys. my base mesh is 32,000 faces and zbrush mesh is 4 million, dmap texture size is 4096x4096 thanks to anyone that can help.
