There is a lot more that does nog transfer ho Poser.

 Bulge maps, scaling, uv map switching just to name a few.

Bulge maps should be working in the current version of the DSON Importer. There's no UI way to switch UV sets, but presets will do in - Mec4D has a free set of presets that change the UVs without changing anything else, though I'm not sure how up to date it
