I did a small test this weekend.
I made MotionBuilder rig. And I downloaded motion capture data from Carnegie Mellon University website. Applied it to my rig, then it worked in Skyrim!
That rough gif animation is untweaked raw mocap data but I heard MotionBuilder has lots of function that polish such data. I'll find it and make it useful to make new "More Vicious Molag Bal Combat animations"
2am Japan, bit sleepy. Have a good night.
