Quote - I wanted to add that, at least on my attempts, it does not seem that the exporter is exporting bump maps on figures.

Bump maps are exported, and work just fine. Keep in mind there is a slight difference in the amount though, so you might want to make them a little stronger in Poser before exporting.

You can also edit the amount of bump in the material file, just look out for "bumpmap" declarations.

And for all you material hackers out there, export yourself an empty scene with a high-res Poser ball and 2 resized point lights (to get area lights); That's the perfect playground for making quick tests.
