Source: A green-screen plate of a medium or close shot of a person talking. They have several tracking dots on their face.
Goal: To add a tattoo to the person's face, that moves with them as they talk, move around, rotate head, etc.
Solution: Anyone?

I can do a 3d camera motion track a surface easily enough, but how would I add a tracked camera that essentially acts like the person's face is a surface, follows it around, projecting an image.

Cheers!

I hope this shot is still in the planning stages.

You will be MUCH better off hiring a makeup artist to create the necessary tattoo than you ever would be trying to do it in After Effects.
It isn't necessary to do it with makeup, all the moves will be natural and spot-on, and you won't tear your hair out trying to make an application with limited 3D capabilities do the job of a very pricey production house.

Yes, still in the planning stage. The trick is, the face tattoos need to animate as the people talk and move (they change based on a person's mood/thoughts), something like what Rorschach's mask does in the Watchman movie.

Richard

A powerful tracking application like Mocha AE(Comes with AE CS% and above) will help.

See the Similar Tutorial by Eran Stern :




I would suggest you to learn Mocha first :

The way that I would do it is to closely model they area of the head where you need the tatto to be. Then put a material on the model to match it. Go back into after effects and put the model bakc on using the tracked footage then change the blending mode to something like overlay, and possibly do something with some inner shadows.

To get the model you would need to have the model annimated in a 3D program and to do this you would need to first track the head with the 3D camera tracker then export the scene to the 3D program. To do this you would need to gogole the AE 2 3D script.

If this seems complicated you might try just puling a 2D track, compositing the tatto agian with maybe an overlay blending mode. Then use some of the different ditortion effects to make it look like it is stuck when the head turns.

Also there are a couple of good tutorials by Andrew Kramer that might be a little bit helpful:
