I'm a novice at game developing and handling Bullet. But when I try to find some way for the 3D artist in my group to export .bullet file for me, I have no idea how to achieve it.

However, those 3D artists use only 3ds 2012 and I have no choice. I just can search for the available way for 3ds 2012.
I've found a lot of internet information about relative topics, but in vain. So if anyone knows how to export .bullet file "only" from 3DS MAX 2012, plz inform me, I'll be thankful for your help!
Oh, by the way, my English isn't very well, if there's any description not so clear...just forgive me.
Best regards,
Wolf Lai
