I am not 100% sure of what I am going to tell you, but this was true some time ago and I don't think it changed since. Yes you need to convert your 3d models to acc to run them in OSG. In fact if I am not mistaken, it is in fact the only way to have it not to crash. In fact the acc file gets converted to osg format on the fly.
