Hi Jarret,

if you don't want to link each mask vertex to a separate Null but rather want to influence entire regions of the mask shape with a null, Tracker2Mask's local mode is also an alternative. Essentially, it creates circles and if you move a circle all mask vertices contained in it move with it. You can also animate the radius or even feather the circles to only influence vertices partially.

Here is a tutorial showing this technique:

You should be able to do this with TrackerViz. Make sure it's set to use expressions rather than keyframes, and the mask should update live as you adjust the nulls.

Subject: [AE] Controlling mask positions with nulls

Hi everyone,

I'm working on a project where I really need to be able to control a mask's position with a null or another layer. In other words, if I move a null from point A to point B I'd like the mask to follow. Moving the entire layer that the mask is on is not an option unfortunately. I should also mention that there are multiple masks which need to be controlled within the same comp.

Many thanks
