Yes, there is. Of course I've forgotten everything about this utility, what it is called, where it is found. But then, it was a PC-only tool (sigh). I do know that both Vue and Carrara have decent render engines and provide (for small extra charge, depending) a realtime Poser importer. Nice thing about that, besides the import ease, is that you can make changes in Poser and have them reflected in the scene you are building in the other application.
