If you have Bryce 5, try exporting it from Bryce as an .obj by opening the Edit Mesh Dialog and hitting Control+D (I think that's the key combo!). Load this .OBJ in Poser (it'll come in as a single object), select the object and hit the Group Tool. In the top pop-up should be all the parts - don't select any, just hit the Spawn Props button, this should seperate all the parts. Now remove the original single object. HTH- Dan
