Strange distortion in assembly import

[jeffw]

I am scratching my head on this one. When I bring in this assembly one part has a strange pattern on it. When I bring it in alone without the assembly it looks fine. It is not a reflection because when I go to 'show only' it is still there. I checked the part in SolidEdge and the geometry is good. Imported with highest tessellation.

Could there be multiple objects on top of each other?

There are not multiple objects either in SolidEdge or KeyShot.

I tried importing using the beta importer without the accurate tessellation checked and the part came in without the distortion. Don't know why but I am happy to have this resolved.
