Thank you very much for your input and possible solutions. My apologies for my late response, but I was doing a lot of test renders and couldn’t figure out what I was doing wrong. I tried varying the scale settings of the subsurface, with no real effect. I saw the pattern change but it wasn’t going away really. So then I tried appending the model in a new blender project and it was gone. Then I remembered that I had reduced the max bounces for optimizing render speed in a high light set up, but that might have had a bad impact on the subsurface in a low light set up. So I will now have to re-evalute the light paths for this new set up. Thanks for the help. And Omar, yes this has been a project that has grown in the making. I started with the human course last year October and then I kept adding and adding… I have learned a lot. Looking forward to starting my second character in the near future.
