Ironic Paradox:
Thank you for the information. I was using Ward’s model in the first image my previous post. I am curious as to where they use this D_GGXaniso function?
As far as parameterization goes I see that some offline renderers use anisotropy and an ‘angle/rotation’ map was wondering if you know anything about that? I think it would be easier to create grayscale maps.

I switched to the GGX anisotropic function.
