I made a little .jsx-Script for automatically linking dummies to footage that was tracked with the AE-Facetracker. Just select the tracked footage and run the Code in a .jsx-file. It will create a dummy for every facetrack-feature.
I used it to animate a kind of facescanning effect with animated solids and plexus. I thought perhaps some of you may find it useful. Feedback is of course appreciated.
Have fun with it.
