Right did several more tests, no matter my render settings, low or high I still get these shadow faults, and they seam to coincide with the polygon mesh, but are not at the seam boarders. I'm pretty much stumped on this one. I have included a full face render on low settings and a test rectangle render of the arm ignore the white triangle that's just light through a triangle.

Getting old and still making "art" without soiling myself, now that's success.
