How to stick Liquify effect to a tracked object? (CC 2017)

Hi.

I tracked motion of an object in a video footage, applied tracking data (Position only) to a Null and then pick-whipped Liquify's Distortion Mesh Offset to the Null's Position and as soon as I did it, all visible Liquify effects disappeared from the footage. I would like the Liquify to stick to the tracked object. How could I do this?

I'm using version 14.0.1.5

Thanks

    You could want to add " + value " to the expression created by the pick whip and then scrub the values to offset them relative to the tracker to get the liquefy where you want it to be. That might work in some cases.

    Two things:

    1. You might consider updating, the latest version is 14.1.0.x, so you're missing some bug fixes. (But don't update if you're in the middle of a project and everything is working fine, of course!)

    2. This tutorial is perfect for you. It's an oldie, but a goodie.

    Hi Szalam.

    Yes, that tutorial is great and I did solve my problem with it. However, i feel that in some cases attaching distortion effect to a tracked object using a pick-whip would be simpler.

    I stated earlier that I "pick-whipped Liquify's Distortion Mesh Offset to the Null's Position and as soon as I did it, all visible Liquify effects disappeared from the footage". Actually, the distortion did not disappeared - it moved to the lower right corner (I noticed it only recently). So, I thought maybe I shouldn't apply tracking data to a Null but to a Solid of the same size as my Comp, but it didn't help. By the way, when I try to pick-whip Magnify effect to the tracked object's Position, the distortion doesn't move somewhere to the lower corner, but some 100px bellow the original location. So it seems that different distortion effect reacts differently to the attempts to pick-whip them to the tracked data.
