WASD to move, Shift to run, Q to transgender(???)
You've got too many built in features and it's complicated to use, more like complicated to learn. I disabled a lot of them, but I forgot to remove access to the default overlays.
I extracted the frames I needed, retargeted the animation to ALSv4, and created a montage that only affects the spine and arms. Then I layered it on top of the default overlay in a semi-procedural way by forcing it through the animation instance.
