Referencing the expression of another layer
by Ben Frank on Nov 4, 2009 at 5:57:36 pm

So i have a somewhat lengthy expression that will be applied to all transform properties of all layers in a project. i would like to be able to easily update this expression and have that update ripple through all elements using it. my question is: is there a way to dynamically copy the expression of another layer? does the expression field itself have a name that i can use to copy it?

i want to do something like this:

thisComp.layer("layer_name").transform.position.expression;

where "expression" at the end is whatever the name of the expression field is. any help would be greatly appreciated.

Unfortunately no, you have' to manually update it one by one every time you change your expression.
But a simple script may do what you want.

Dont know of a way to auto update it but the is a "copy expression only" option in edit that should make what your trying to do pretty painless.
