Lighting Diffusion Material tests

by Ed Moore and Stephen Murphy. See Stephen's blog post for full details and here's the video results.

For each setup, we have given the amount in stops we had to adjust the aperture to maintain the same exposure compared to the 10K fresnel direct. This will give you an idea of the "cost" in light loss of each method of diffusion.
