LayerMark for After Effects

A simple script that let's you choose a layer with multiple makers, and then auto align LOTS of other layers to those markers.

1. Run Script
2. Set the layer with markers
3. Selected all the layers you want to align
4. Done
   

If you have more layers than markers available, the script will just bunch up all the remaining layers to the last markers so you can easily view how many you have left.
