Control rig procedural: In this tutorial (TC 06:30) https://youtu.be/6a8e5GkHWMk?si=RpULXyf4AXGqiiYp&t=381 the tutor shows that a UE5 mannequin’s extra joint bones are moving along the elbow while it rotates - in order to give volume to the hand. How can I transfer this feature to another character that has the UE5 skeleton? Thanks
