Well the source file is what is giving you unsatisfactory results. FBX works great in my experience. Do you have MotionBuilder? COB and LWO files I've downloaded from the web, about 8 out of 10 have been crappy, but that was due to the source file not being that good. Many free models on the web are not the best. Perhaps if you could be more specific as to what problems you are having we could help you. Brian
