Hello ,
Thank you for posting in the community and it seems like maybe you are experiencing a known issue we are working on resolving regarding morph elements being misplaced. The udatasmith format seems to have this problems occurring much less often at this time.
If the elements in questions are morph objects you can sometimes rectify the issue by resetting the 3D texture origin or reapplying it to each elements.
If the problem persists please submit a bug report by using the [ contact us ] button from the home page or by following this link:
