This program would be grande if it supported poser pz3 files, all one would have to do then is just import and model there figure then export and ready to go, is this possible?
Poser will export OBJ, which ZBrush can import.
However, the pz3 format itself is proprietary to Curious Labs.
In this thread I explain a technique for easily importing groups of models from other programs. Hope that helps you!
