SurfaceError

Hello, as you can see at the attached image a have some ghost areas in render, it also happens in Ghosted and Shaded. Ive alredy run _SelBadObjects command. What can I do?error

Hi @valenperea1127
A couple of things to check:
a) Is the object very far from world origin (0,0,0)? If yes, try moving it closer and see if that fixes things.
b) Try to untrim the surface, keeping the trim curve. Check the trim curve for errors and maybe try to either rebuild or refit it; then retrim the surface using the rebuild/refit curve.
