I use OS 10.2.3 everyday with Bryce too and I've also encountered this problem. The 5.0.1 patch doesn't fix it and the workaround is to do exactly what the program was expecting - put all the textures in the folder that the .obj is in - then it will not crash and you textures will come in right with your model. The last time I did this it was pretty cool - I didn't even need to 're-texture' the surfaces - it read the .mtl file correctly and everything was ready to go on import. Scott
