It's nice, it isn't a perfect conversion but it's really very close to Poser.  You can also do things like add conforming clothing or smart props or load pose files from a single very clean, visual interface, you pretty much don't need to enter Poser at all once you commit to working with it.  The only thing that needs really serious attention right at conversion time is materials settings, but Robert may decide to bundle some skin shader setups with it in the future; and I'm making my own work in that department public once I get it finalized (pretty close now).  Plus magnets don't import at all, which means V4 has stiff boobies, but that can be addressed with C4D's own deformers as required.
