IK/FK Matching
A common problem when implementing the ability to switch between IK and FK is a visual "pop" in the animation at the point in the timeline where the switch occurs. An animator can spend countless amounts of time trying to match the previous pose and never get it exactly right.
This has been solved by using a small script that reads the transforms of hidden dummy objects and applies those values to the resulting rig.
- Works on both the arms and legs
- Match IK to FK or the other way around
Moveable Pivots
There are times when the easiest way to get the motion you want is to adjust the placement of a pivot. Perhaps you don't want the head rotating from behind the ear but the lips or forehead instead. Or perhaps your character is falling through the air and you need to animate them spinning around their center of mass and not their hips.
All of this and much more can be accomodated by this rig. With the help of a small script, new pivots can be created with ease allowing you to control where a joint will rotate from.
