PINS TO NULLS
This function creates and places nulls where AE Puppet Tool pins are located on the selected layer, then connects them via expressions. If you're a frequent Puppet Tool user you know what a pain in the butt it is to animate with, especially when you have a lot of pins and separate layers of artwork. Hopefully this null workflow makes things a bit easier.

CREATE IK
The new ‘Create IK’ feature offers an easy way to use Inverse Kinematics (IK) in your rig. Select three nulls (starting with the driving joint) and then click ‘Create IK’ – done. It was designed to work with this puppet script, but can be used on any three nulls.

LAYER TO LOOP
This function automates the process of looping an animation cycle. It time remaps the selected layer and applies a loop expression to it. You have the option only loop a finite number of times, or loop endlessly. If the selected layer isn't precomped, it will do that for you.
