Bad render geomtery

No, just a vraynomral with a bitmap

Try a smooth material with a bump map

The diffused works, it is the bump that gets wonky.

Normal map render just fine. It’s Corona not Vray, but i don’t think that would make any difference.

Are you saying that for you, those bits you posted render incorrectly when opened, literally as they are as you posted, so just those parts and nothing else?

If you have errors and nobody who has looked those parts has found issues, then maybe it’s something else.

I talked to the department manager awhile back and he said that they have spent numerous hours troubleshooting it and never found a solution - way before I arrived.

Just to clarify, that render I did with the brick above also was using a VrayNormal with a Normal texture (3dsmax 2024). Didn’t notice anything strange either.
