I did it the messy way, I installed P4 again in a different directory and decoded Bloodsong's file with that .obj file. Then I copied the files into my current P4 directories before deleting the newly installed P4 copy. (A mess..see? I also had to make sure that the shortcuts pointed back to my original file directory) I think I know what happened: The Animal CD and the P4 animals both put the geometries into the Zygote Animals directory. Obviously the geometry I have was the for the Animal CD frog. I guess Bloodsong's frog works with the P4 frog only Tina
