A method that I use to transfer Poser files to Bryce is to save the figure or scene as a wavefront .obj file in a separate folder, appropriately labeled.  In that folder, I also place a copy of all the the texture files needed for the figure, its clothing, etc.  Then I go to Bryce and import the .obj.  It will normally transmit everything with the textures included in the Bryce image.  The only problem is that .obj files don't tranfer alpha or transparencies, so I usually have to ungroup the figure and import the tran files into Bryce via "Leo"  and save as a Bryce material file.  These means that eyelashes, brows, and hair have to be turned into Bryce mat. files; also any clothing transparencies.  This method is a bit cumbersome, but it works in all versions of Bryce and Poser in any combination you wish.   I don't especially like DS and still do it this way despite bridges and all that other stuff.
