This is both the SSS pass and final pass. The SSS pass clearly shows the circular pattern on the bridge of the nose. Interestingly this took 2 seperate renders to produce and the results of the black pattern were not identical each time. Absolutly no changes were made.

I dont know if that could be caused by voltage fluctuations or memory fluctuations. Ive never seen 2 renders vary with no changes in settings or camera. The dark shadows around the eyes are also messed up.
