I made an oreo cookie with a bite out of it. When I went to render it, it had these awful artifacts.
It’s a fairly simple mesh, lit by a sun lamp (I’ve also tried hemis, spots, and point lamps, same problem.) The normals are all pointing out of the mesh. Here is the filling with normals showing.
There is nothing particularly fancy about the material, low spec, low hardness, a stucci bump map on the cookie part, mapped to nor at value 2.0.
Any ideas on what could be causing this? Should I post the blend?
