Use script to batch change all smart object layers to a new pattern

[josh.hues]

Hi All,

This is my first post ever so first I apologize if this topic has already been discussed or reviewed. Secondly I hope I am posting in the correct section of the community. I also have never used the Script tool so this is all new.

Getting to the point.

I have a .psd file that is a rendering of a sportcoat/blazer. All portiond of the sportcoat have been turned into masks and linked with a smart object so that new patterns can be applied to the smart objects to adjust the rednering to different fabric patterns.

What I am trying to achieve is a workflow to automatically apply new .png patterns I have in a folder and export a .png so that I have an rendering of every fabric.

I have attached some screen shots to better understand the file structure.

I am open to ideas or better practices. The end goal is having a realistic as possible rendering of the Jacket made up in every fabric I have.

In respect to the fabric patterns I have both large swatches and smaller clips of those swatches I have turned into a tile that will seamlessly repeat.

Could you please post screenshots with the pertinent Panels (Toolbar, Layers, Options Bar, …) visible that illustrate the Layer structure of the template file? 

There have been several threads about batch-replacing Smart Object contents in templates, have you done a Forum search yet (for »smart object template script« for example)?

I’m going to use an example of an action, however, to my knowledge scripts have the same requirements... But some creative advanced Action Manager coding may be able to work around the following complexity:

Changing a pattern requires both the "obvious" pattern name, but also the internal ID of the pattern.

In trying to help someone in another thread I noticed that, at least if Patterns have unique names, it seems the names suffice for identification of a Pattern in a Script. 

Edit: 

// create pattern layer with last pattern;
// 2023, use it at your own risk;
if (app.documents.length > 0) {
try {
var ref = new ActionReference();
ref.putProperty(stringIDToTypeID ("property"), stringIDToTypeID("presetManager") ); 
ref.putEnumerated( charIDToTypeID("capp"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") );
var applicationDesc = executeActionGet(ref);
var presetManager = applicationDesc.getList(stringIDToTypeID("presetManager"));
var patternNames = presetManager.getObjectValue(4).getList(stringIDToTypeID("name"));
var theNames = new Array;
for (m = 0; m < patternNames.count; m++) {
    theNames.push(patternNames.getString(m))
};
makePatternLayer (theNames[theNames.length-1], 100);
//brickFill (theNames[theNames.length-1], 0.1)
} catch (e) {};
