parenting expression

Hmmm…. It works for me. The child will mimic the movement of the target, even if the target has no movement of its own and is only animated by the motion of its parent. I must be missing something…

Hi Dan

So sorry… I should have tested it further before responding. When I set it up (footage layer with null target), moving the null produced no movement in the layer. However, if I link the first null to another and move that, I get the desired movement. So it does work!
Thank you so much Dan, I cannot overstate how much I appreciate this. It’s a super useful bit of script and I have been trying to crack it for over a year but, yeah, I am just not that good at scripting…! Cheers,

Pete

It should work either way, but the target has to animated, either by keyframes or an expression applied to the layer itself or its parent. If you just drag it around, nothing will happen.
