  How to create an opossite wiggle expression

  Posted by Alex Orfanidis on March 13, 2021 at 3:35 pm

  I have two photoshop layers of a window, one yellow (for when the lights are open) and one dark blue (for when the lights are closed). I’ve created a wiggle expression for the opacity of the first one (so it flickers) and now I want to create the exact opposite for the second one, so when the first one drops in opacity (e.g. to 25%) the other one will increase by the same amount (75%). How can I do that?

  Something like this should work:

  100 - thisComp.layer("Layer A").transform.opacity;

  You are absolutely right! Thank you so much. I’m guessing that this will also work with any other transform parameter so it’s even more helpful ?
