I got so many errors in the mat files, because the program was looking for .bum files and everything was a .jpg, that it kept crashing Poser. When I tried to open the dragon again after a crash, the obj file was always corrupted and I had to keep removing it and reinstalling it. Eventually, before loading any mat files, I went through all the model, loading the jpgs for bump files so that the program made the necessary .bum files. Now the dragon and the materials all load with no problems. I did not notice dragon poses. I must have missed something. Back to Daz3d.
