Troubleshoot highlight artifacts close to object edge

If you have tessellated an object with the Use Smooth Edge attribute and you get artifacts in highlights along curved parts of the surface close to an edge, don’t use this attribute. This caused the curvature in the surface to be slightly different closer to the edge, which doesn’t work for strong highlights.
