Liquify position…

Not hard: use expressions.

After you’ve tracked the point, you’ll need to add a Expression, Point Control effect to the layer. Then you do your distortion mesh the way you like and link the mesh offset to the tracker attach point using the pick whip. This is okay, but the mesh won’t stay on the point, because the coordinates are slightly offset. To fix you rewrite the expression to something like this:

temp = motionTracker(“Tracker 1”)(“Track Point 1”).attachPoint[0]+effect(“Point Control”)(“Point”)[0];
temp1 = motionTracker(“Tracker 1”)(“Track Point 1”).attachPoint[1]+effect(“Point Control”)(“Point”)[1];
[temp, temp1]

Then use the Point Control expression controls to slide the mesh to where you want it to be. After that, it should stay stuck to that point.
