"Software houses are more familiar with the fact that users will do some pretty weird things and have, in my opinion, made the software more robust as a result..." True, but not all .obj loading programs are the multi-hundred/thousand dollar applications you mentioned ;). I have several commercial, shareware and freeware modellers/converters on my system that may not be quite so robust. I'm not pointing any fingers (and some of these may handle this particular glitch fine), but am speaking about apps like 3D Canvas, Milkshape 3D, Wings3D, Anim8or, etc. I still stand by my (admitedly anal) position that if you're going to hack data files, you should attempt not to corrupt them in the process ;). It's one thing if you don't plan to distribute your files, but future users of your products may not be using those high-dollar apps. Then again, that's just my opinion - I could be right ;).
