Is there a REAL mask tracker for after effects ?

[Tero Ahlfors]

I don’t know if it counts as a REAL mask tracker but AE has had mask tracking for a while now: https://helpx.adobe.com/fi/after-effects/using/rigid-mask-tracking.html

There’s also Mocha AE that comes with After Effects.

Are you specifically referring to when the mask is tracked by using its control vertices as the feature trackers in order to animate the shape?
Then as far as I’m aware, no, this does not exist in After Effects.

If you just want a tracker that tracks object texture over individual features, then use Mocha AE (or Mocha Pro).

You may also find some use for this tool, but I don’t think it’s what you’re after:
