Hi Mike,
I found the material in mesh have a strange shadow,just like some triangle in the mesh always been flikering.
I found my mesh crinkling and it turned out It was because i was using VectorDisplacementMap which was compressing and causing artifacts. Switching to HDR or another FloatRGBA format solved the issue for me. Thought i'd mention this in case anyone else was running into a similar issue.
