The UV Map information between the 2 are completely different. Look at a P3 template and a P4 template for the same figure. The head is larger and in a different position on the P4 template, plus other body parts. Since the obj takes it's map information exactly from the template you can't use a P4 texture on a P3 obj. The only way around this is to use a program like UVMapper and remap the P3 obj. But you would have to exactly match the position of each part to the texture. Not for the faint of heart. Another way is using the UVMapper again for each body part and cut and paste from the P4 texture to match your new template. Then import all of these into Bryce. Very time consumming. I hope this helps. James
