So after all this time I am back resurrecting this thread because I made a very interesting discovery!
I was poking around with retargetting animations and I managed to port a mocap animation from Mixamo to the game! Thanks to the "Unapply object keyframes" feature that KotorBlender has, I could retarget the animation from the Mixamo armature to the Kotor armature.
At first I used the Rokoko Blender plugin to retarget the animations and the results weren't half bad, but then I tried with Auto Rig Pro and the results were even better! Here's how it looks in Blender:
And here's ingame:
I will keep experimenting on this. I may try to retarget the TOR rig to the Kotor animations like @DarthParametric and @JCarter426 were doing a few years ago, although I don't know how that will turn out.
