Why does Kray mess up my UV surface?

[ZodiaQ]

Don't know what's going on but kray seems to be messing up my UV material while fprime and native LW render seem to render just fine.

Must have been some corrupted and/or double geometry?
Still strange that fprime and LW didn't bother.
re-modeled and all is fine now.

Problem with geometry. I see wrong import from V-ray. You can use LWCAD Fix polygons or merge points, etc.
