1. Re: Is there a way to motion track a point in a shape layer?
Mylenium Sep 1, 2010 1:59 AM (in response to Editor Naama)No. It's the same as for masks. AE does not do per-vertex tracking or any sort of diskrete vertex animation for that matter.

2. Re: Is there a way to motion track a point in a shape layer?
Dave LaRonde Sep 1, 2010 8:20 AM (in response to Editor Naama)As Mylenium points out, you can't to it directly. But if you're willing to jump through a hoop, you can: Precomp that shape layer!
Now AE will see it as another piece of footage, which can be motion tracked. You can use Mocha or AE built-in motion tracker, depending on the nature of your precomp.
Alternately, you can simply parent a null object to the shape layer. After you do so, you can adjust the null's position, positioning it precisely where you want it to be in relationship to the shape layer. It will then maintain that relative position, following right along with any animation applied to the shape layer.

Editor Naama Sep 2, 2010 1:15 AM (in response to Dave LaRonde)Thanks to both of you for your answers.
Dave, I tried to motion track a specific point of the shape layer. I can motion track the whole shape layer but in the path there's no information about the points.
I couldn't see any difference to that when I use a precomp or a null. There still isn't information about a specific point.
Did I miss anything in your explanation?

Sure there is: using expressions, you can pick-whip to the null's various transform properties. Very handy.

Editor Naama Sep 2, 2010 10:15 AM (in response to Dave LaRonde)Thanks, that's good to know! I'll have to check into that more thoroughly.
