Hi guys.

I am having a problem with a few artifacts when rendering with misss_fast skin shader. The scene is lit with 2 area lights and Final Gather. Rendered with mental Ray. As you can see in the pic, there is some strange white lines around the eye and mouth, this is also occuring on the leg. Im not sure if its to do ith the lighting or shader or both.

heres some settings.

Sampling Min - 1
Max - 16

Filter Type Michell

Scanline - on

FG - on

Standard High Settings with Max 9. 500 samples.

Misss_fast_skin with 64 samples

Ive cropped the image to show you the problem, the original render size is around 1200x800

appreciate the help

thankyou

I see those white lines practically everywhere. Looks like some kind of biasing problem with the light/fg or maybe even some problem with the tesselation of the mesh (if you have one). Turn of FG and test, than delete all the lights and just place a clean new light and try and maybe replace a possible tesselation with a mesh smooth. I doubt its the skinshader, at least never encountered that result before.
But im maya user so I cant be sure:)
