    Hello guys, i have an AE Project with 50 compositions, in each composition i have 2 shape layers, i need to apply one .ffx to the first layer, and apply another .ffx to the second layer, i need to do this in all 50 compositions, so i think the best option is to do it automatically with a script, can you guys help me?

    The basic structure could be something like this, but I’d probably add some additional checks to make sure the comp has the layers you’re expecting, that they’re not locked, etc.

    var preset1path = "/c/test/preset1.ffx";

    var preset2path = "/c/test/preset2.ffx";

    var myComp, mySelected;

    for (var i = 1; i <= app.project.numItems; i++){

    myComp = app.project.item(i);

    if (myComp instanceof CompItem){

    mySelected = myComp.selectedLayers;

    for (var j = 0; j < mySelected.length; j++){

    mySelected[j].selected = false;


    myComp.layer(1).selected = true;


    myComp.layer(1).selected = false;

    myComp.layer(2).selected = true;
