MacConverter does indeed export to PC, as Daio says: under the Expert menu, choose 'Export to PC...' I just did a little conversion of the Angelfish that comes with Poser4 to see what it would do. It made a PC .cr2 file and an .rsr. It did that for the .obj too; I think it only did that because I left the box ticked. Or do PC .objs normally have associated .rsr files?
