Hi JTB - well this sounds like an odd problem.

I don't have Max over here, so it will be a bit tricky for me to track down what is happening.

If you create a box inside of Max and export it to .3ds, does that work correctly when you read it back in?

If it does, could you please post here the .3ds file exported from Max which does work, and also the .3ds file from Moi that doesn't work? I will then try to compare them and try to see what Max doesn't like about the MoI file.

Maybe something with your video card is behaving oddly, it might be a good idea to reboot your machine and try it again.
