  • Fade In and Out random layers in a composition.

    So I have 4 layers in a composition. It’s the same image repeated, except each one has a different Photoshop effects on them. What I want to be able to do is an opacity fade from one randomly selected layer to another. Would really appreciate the help.

    I’m sorry, so is that your way of saying you can’t help? Do I have to assure you that I do need this? I don’t understand…

    You can try with a fade expression for the layers. After you apply it to one layer you can copy the expression and select random layers and choose “Edit” – Copy Expression Only.
    Here’s the expression:

    fadeInTime = .5; // time (seconds)
    fadeOutTime = .5;

    Math.min(linear(time,inPoint,inPoint + fadeInTime,0,100),linear(time,outPoint – fadeOutTime,outPoint,100,0))

    If you’re not sure how to do it, here’s a tut on that:

    Hope this helps
