Makes sense! I vaguely recall there was a reason I had to use the PySide2 import at the time, but don't remember why.

What Substance Painter version did you test this with? (Did they update PySide versions, or we?) I wonder if this would still work with the older Substance Painter versions?

Other than that, change looks good! I don't have access to Painter myself currently; so can't test.

I was testing with their latest.
there is also some bug when collecting the texture set in the latest version of substance. So when I tested with the tx, I was actually testing in one version elder than the latest.

Can you create an issue for this with the bug/stack trace?
