After we split up the character into parts, we go into the next P, which is Pivot.
The pivot point has to do with the rotation points of your parts and how the act as joints.
The pivot point also affects the general point of transformation, like scaling.
In OpenToonz we use the Animate Tool in the Center Mode to place the pivot point.
See Part 1: Parts.
