Note:
For kinematic motions to work, a child's pivot must be in the same alignment as its parent's pivot, and all pivots in a chain of child-parent relationships must be aligned in the same direction. The child pivot location determines where the link is applied and the parent pivot location determines the link orientation and movement. For example, all pivots could have the Z direction pointing up or down. Use
Align Pivots to copy pivot alignment between specified actors.
