Hello,
I was following an official tutorial:
How to export from the CC3 the Character (Body only)  and Import it into Marmoset Toolbag.

When I export from the current CC3, then the maps (texture sets) were NOT assigned.  (So baking normal maps was not possible.)

When I export instead as FBX ("clothed character") they were assigned. But this wasn't the recommended workflow.
What could be the reason, why is OBJ not working?

Thanks for help.
(I have also 3DXchange/pipeline, just in case that this matters)
