Quote - Oh, double export? I didn't even check the output that far :-).
But maybe this is interesting to you then: The warning only appears for the prop when the figure is exported not when the prop itself is exported.

Yes, things are starting to make sense now. If a figure has UVs and there's a prop parented to that figure that doesn't, the exporter still tries to create one single mesh out of those with the UV polygons matching the polygons for the geometry, which obviously it can't. When the prop gets exported separately, the UV data is simply noted as missing, and all processing related to it is skipped.

In this light, it would probably be best to exclude parented props from the figure export and let the separate prop export take care of them. I'd have to think a little more about the best way of dealing with potentially existing figures that have UVs on some actors but not on others. I'm not quite sure how Poser would handle that. Maybe I'll do some testing.
