Thanks for the response. Yes, air supplied a renderman shader. It has 3 attributes. Light shadow fraction, max displace, and target space. Our renders are currently solid flat yellow (0.5 in the red and greens throughout the image). Changing the attributes in the shader provides the same results in the render. Our alpha pass lines up with our beauty pass. We aren’t sure what settings to use in the shader and in Air’s motion blur to get the correct result. I am emailing you two frames right now with our results thus far.
