Here are the results from my motion test with the material applied to the sphere. I fixed the environment shadow maps, so the shadows on the ball appear cleaner and more accurate. I am happy with the way the ball looks as it moves through the light and shadow; however, I still need to tweak the shader. I plan to work on that next.
Also, I was able to match the lighting in Houdini as well, so that my partner can use Mantra to render his effect within Houdini. We plan to render our objects separately and composite them together. This is because David's effect is very shader dependent within Houdini/Mantra, so we have been unable to export the simulation into Maya while preserving the look of the simulation. Here's a render of the lighting match in Houdini/Mantra.
