Delete root animation in blender
This is how you can delete root animation so that the animations are in place and do not move in the world space. I can think of 5 different ways to do this exact same thing. But i think this way is pretty simple so thought I would share it.
0:00 - Mixamo lets you tick in place for in place animations
0:59 - Delete root animation on z
1:36 - Set linear interpolation
2:00 - Ya done
