If you run your obj through Grouper before importing into Bryce it has a function to convert bum files to jpeg or bmp. You should also try to copy/paste the Poser textures you're using into the same folder where you keep the obj, 'cos then you know where the appropriate textures are and you won't have to go hunting for them again I always use Grouper before importing to Bryce it solves all sorts of problems like creating a new mtl file, etc. You can get it at the link, and another good thing about it, is it's free. 8) Catlin
