Hi @PascalKrebs! Sorry to hear that you are having a difficult time with the software. Are you experiencing this in all Stager projects? How are you generating the UV map?
When generating UV maps within Stager, make sure to convert parametric objects to a standard model, then go to objects > generate UVs.
We are not able to diagnose working files directly on the forum website. Can you email the Stager log file from the scene you're trying to publish to Substance3d-bugs@adobe.com.
Thank you
