Select the layer(s) you want to attach to a motion path
Add to your selection any masks you want to use as a motion path (IMPORANT – Select the Mask NAME, not the Mask PATH)
Run the script.

Interface Options:

Keep Position Offset
Keep the layer at it’s current position
Auto-Orient to Path
Should the layer by automatically oriented while following the path
(Note: Auto-Orient only works after an initial keyframe is created on the Motion Path Complete slider)
Updating Paths
Every path you add will show up in this listTo update them do the following:
1. Edit the original Mask Path (The path can not be animated)
2. Select the Mask(s) you want to update in the GUI
3. Click Update
All your connected layers should jump to their new positions
Any existing keyframes will stay in place
Use the “Clear” button to empty the list
(This is necessary if you undo the adding of a motion path)

Control:

Motion Path Completion
Animate through all of your paths sequentially
When this is activated, the sliders for individual paths have no effect
Complete Sequentially
How far along on the motion path(s) the layer is. Range 0→100
One slider per motion path
You can animate what % you want each motion path to contribute
If all sliders are set to 0, then you can set a keyframe like normal on your layer

The sliders are only valid in the range of 0 100. If the slider is moved outside this range, it will get calculated as 0 or 100
(All sliders are normalized to 100% — The values are added together, and divided by the # of sliders.)
The script makes a null per each of your motion paths. However, they are put as the last layers in your comp, locked, hidden, and set to shy mode
If the Mask Layer is rotated or scaled, motion paths will not reflect this (the same as when copying a mask in the interface)
Even with Orient Along Path selected, you can still animate the rotation of the layer like normal
When using Complete Sequentially, the masks will complete in alphabetical order
