Ok I can't sleep lol Ok here's my data! If only I could take screen captures.
My blinn node is plugged into the alternative_specular node, and haseccentricity at 1.00 and sec roll off at 0.0006 and the reflectivity at 0.0007. I have no Gc at all and the lighting rig is simple-1 ibl light at 100% intensity, 1 grey main light at 50% intensity and one spot light at 57% intensity.

Anything else you would like to know?
