Hey ,
So in order to assist I will need the assets your are using and an outline of the process you are following so I can reproduce the issue on our end.
Also, the GEOMETRY SEEMS FLIPPED
This is a known and reported issue which you can track by following the link below to our Public Issues Tracker.
I believe what you are seeing is just a side effect of the importer flipping the axis and causing your UV’s to appear offset. I could be wrong though, so if you could provide me with your mesh to test with, I can investigate further.
Thanks,
