Terry- <<If you have been doing booleans, the smoothing groups could be invalid. There could also be subtle differences in the orientation of the faces that could pick up difference highlights if the material has shininess.>> The object was created in AcadR13. The smoothing groups appear to be valid, at least they follow what I would have done if I were smoothing it. The differences between transparent areas and opaque areas are very sharp and occur on flat surfaces where a highlight would be uniform. I may try recreating the object and bringing it in again. -Scott.
