RE: tracking the movement of one composition and adding it to another

Question

Hello,

I have a drawing of a hand that I have animated using the puppet tool. I have animated the fingers here (different layers) with the puppet tool giving them movement so they go up and down. I have also got light compositions and would like these light compositions to follow the movement of the fingertips. What is the best way to do this?

Not really a good way, I would assume, since typically Puppet pins are not necessarily where you want them for parenting/ linking to expressions, but as @Szalam suggested, start by looking into simple pickwhip expression linking across comps. This may need to be expanded using layer space transforms like toComp() to get correct coordinate conversion and other math, though. Impossible to say without seeing your actual mesh and pins and in fact you may have to re-do it to better work with what you intend to do.
