Brilliant, thanks Dan. Not quite how I thought applyPreset() would work, but your code lets me achieve the desired results anyway.

Thanks again,

Steve.

Hi Dan,

Your code works for me too. My problem is not adding the preset when I create the layer, but adding it later in the code. In the following test I’d expect the preset to be added to the layer called ‘Preset_here’, but instead it adds it to the last layer created (Test2).

// Test script

var myComp = app.project.activeItem;

// Create layer that preset should be added to later
var importantLayer = myComp.layers.addNull();
importantLayer.startTime = 0;
importantLayer.source.name = “Preset_here”;

// Create a few other layers
var testLayer = myComp.layers.addNull();
testLayer.startTime = 0;
testLayer.enabled = false;
testLayer.source.name = “Test1”;

var testLayer = myComp.layers.addNull();
testLayer.startTime = 0;
testLayer.enabled = false;
testLayer.source.name = “Test2”;

// Apply preset to 1st layer created (‘Preset_here’)
{
var presetPath = “c:/Program Files/Adobe/Adobe After Effects CS4/Support Files/Presets/SR/light_sweep1.ffx”;
var myComp = app.project.activeItem;
var importantLayer = myComp.layer(“Preset_here”);
importantLayer.moveToBeginning();
importantLayer.enabled = true;
var myPreset = File(presetPath);
importantLayer.applyPreset(myPreset);
}

Hi Dan, thanks for the response. Unfortunately I get the same behaviour. I’ve also tried the following experiment:

//Add and remove temp null to clear any existing selection

var tempLayer = myComp.layers.addNull();
tempLayer.moveToBeginning();
tempLayer.remove();

// Move Cam_Null_ST to top of layer stack

var mySTLayer = myComp.layer(“Cam_Null_ST”);
mySTLayer.moveToBeginning();
mySTLayer.enabled = true;

// Add preset to 1st layer in stack

var firstLayer = myComp.layer(1);
firstLayer.applyPreset(thePreset02);

Again I get the same behaviour – rather than adding the preset to the existing first layer, a new layer solid is created and the preset applied to that. I’ve also tried applying different presets, in case there is something odd in the preset code, but it still creates a new layer.

Steve.

Perfect! Thanks Filip.
