Someone on the Poser forum identified the problem.  Poser's general preferences can be set for external binary morphs.  If a figure is saved to the library with that setting, then Carrara 8.5 Beta won't recognize the morphs in the parameters tab.  If the Poser's general preferences are changed so that the box for external binary morph targets is unchecked, then the morphs will work in Carrara.  

 

Thanks for your quick reply.
