  Linking properties between comps

  Posted by Geneviève Delisle on July 6, 2023 at 9:01 pm

  Hi there,

  I’m trying to link the position of a layer to the position of a null inside a precomp.

  The expression I currently have is:

  comp("comp.name").layer("layer.name").transform.position.value;

  It’s not working because it takes the position as if the precomp begin at the beginning of the main comp, which is not the case. How do I synch the current position at current time? Thanks!

  Generally, it should look like this:

  comp("Pre-comp").layer("Layer 1").position.valueAtTime(time - thisComp.layer("Pre-comp").startTime)
