Converting V4 to unimesh is a one click process; Figure Menu: Skinning Method: Poser Unimesh... Done. You can then also subdivide the figure in the Body Properties tab by turning up the subdivision levels. For rendering purposes I don't see any reason to increase the SubD above 1 with V4.

Converting the mats to Superfly is easy with one of the aforementioned automations. Learning what's happening with the Superfly materials and the proper render settings takes a bit more work.
