  Inversely proportional opacity

  Posted by Emanuel Lopes on November 23, 2011 at 4:05 pm

  Hi,

  I need an expression that would make a layer follow another one’s opacity keyframes but in an inversely proportional way, so that, if in layer 1 I’ve got a keyframe with 100% opacity, in layer 2 it will be 0% and so on.

  Like this:

  100 – thisComp.layer(“Other Layer”).transform.opacity
