I've been experimenting with Fresnel reflections on skin in PP12, or at least I've been trying to, but most of the time has actually been spent just trying to get rid of these artifacts I keep getting.  The skin rendered perfectly fine until I added the Reflect and Fresnel_Blend nodes to my shader, and while the Minimum Shading Rate seems to be the primary culprit, cranking it up to even 2.7 (worse than the default "Draft" setting) doesn't eliminate them completely.  I would greatly appreciate any advice you might have on how to fix this without sacrificing significant quality/detail in rendering.  Any ideas?  My Shadow Min Bias is 0.0169 (feet), and I tried raising it dramatically to 0.069 with no visible effect.  Raising ray bounces doesn't seemt to help much either.

Thanks in advance!

hi, i'm using poserpro,the version b4 p8, and I 've got something like that several times. When I move the camera a bit, they gone. Or move that part a bit, they gone.

I tested one time that when I add bb's VSS, these black lines appeared, but I just tested one time, not sure it related to VSS or not.

I've gotten the same thing. I found when I brought pixel samples back to 3 from 10, most of the black squares disappeared. I am not sure this is a bug or not.

Try to uncheck "smooth polygons" in your render settings, the lines should dissappear.
