Maybe some normals are pointing "inside" the object instead of outward.
Any luck if you don't use shaded mesh?
Did you try PoseRay?

Anyway, unless your mesh is very fine, there will be some artefacts near the 
terminator, where the incident light comes at a grazing angle.
You can minimize that by carefully placing the light or by using some small 
rotation of the mesh.
