Pretty cool actually!How to use:Select the layer(s) you want to attach to a motion pathAdd 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 OffsetKeep the layer at it’s current positionAuto-Orient to PathShould 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 PathsEvery path you add will show up in this listTo update them do the following:Edit the original Mask Path (The path can not be animated)Select the Mask(s) you want to update in the GUIClick UpdateAll your connected layers should jump to their new positionsAny existing keyframes will stay in placeUse the “Clear” button to empty the list(This is necessary if you undo the adding of a motion path)Control:Motion Path CompletionAnimate through all of your paths sequentiallyWhen this is activated, the sliders for individual paths have no effectComplete SequentiallyHow far along on the motion path(s) the layer is. Range 0→100One slider per motion pathYou can animate what % you want each motion path to contributeIf all sliders are set to 0, then you can set a keyframe like normal on your layer
