Interactively manipulate constraint frames with a graphical user interface.
Open Pivot Editor from the
Constraints submenu in the main Ragdoll.
Here's how to use it to tune a broken knee.
Spin & Swap
One of the main reasons to want to edit constraint pivots is to align the Twist axis with the main rotation of a knee or elbow.
If the pivots face in opposite directions, orientations can be un-mirrored with the
Channel Box Co-op
Tuning limits alongside pivots works well too, middle-click drag attributes from the Channel Box like you normally would, whilst dragging in the UI to compensate.
Use the snap option to make precise adjustment to specific angles.
