  ExtendScript – changing opacty of a shape in a shape layer

  Posted by Mark Chan on October 10, 2018 at 7:16 pm

  Hi. I have a shape layer that has a single ellipse on it. I’ve written a script to duplicate the layer and now I want to set a keyframe and change the opacity at a certain point based on an array value. I just can’t seem to figure out if that property is targetable and, if so, how to target it. Thanks in advance for any assistance! Here’s what I have so far:
  app.project.item(1).layer('shapelayer1').property('Ellipse 1').property('Opacity').setValueAtTime(2.5,50);

  Paths don’t have opacity.

  You’ll have to either manipulate the opacity of a Fill:
  app.project.item(1).layer("shapelayer1").property("Contents").property("Fill 1").property("Opacity")

  … or of a Group:
  app.project.item(1).layer("shapelayer1").property("Contents").property("Group 1").property("Transform").property("Opacity")

  … depending on how your shape layer is set up.
