Original thread and discussion here
Well, ever since I've come out with my new door, people have asked for a tutorial. Well, here it is. And believe me, it isn't for the faint of heart!
I whipped it up pretty quickly, but I believe that it works, I've included two GMax files so you can use those as a start.
Note: You need GMAX! The 3DS max NWMax doesn't export animations. But, you can make your door model, export it without animations, import it in GMAx, and add the animations.
It has been discovered that you CAN use 3DS Max to export animations now.
