Quote - There is also better UV map support, although I'm not sure that that feature works in Poser yet.

It does work in Poser. For example applying the material preset for Basic Male (included) switches Genesis to the M4 UV set. Applying the material preset for Basic Child switches genesis to the K4 UV set. Genesis starts with the V4 UV set, but the Basic Female preset will switch to the V4 UV set. V5, M5, the Troll, Anubis, and quite a few others all have their own UV sets which are set up to take better advantage of their shapes.
