Hello, I looking for a script that can replace a layer with several other layers but keep the opacity and blending mode of the replaced layers.

Link to PSD file: https://we.tl/t-JKd8v0Jx3B

Example: I want to replace "_ELEMENT_SPECULAR copy" with "SPECULAR PASS" layers.

Each individual "SPECULAR PASS" have different blending mode and opacity, and I want to keep those.

New render passes:

Old render passes:

I appreciate all the help I can get!

Select layer to 'replace' others by:

(slctn = (aD = activeDocument)
.selection).selectAll(), slctn.copy()
sp = 'SPECULAR PASS', top = aD.layerSets
lSs = [].slice.call(top.getByName('SCENE ELEMENTS')
.layerSets.getByName('ORGANIC OBJECTS').layerSets)

while(lSs.length) {
	lS = lSs.shift(), lrs = [].slice.call(lS.artLayers)
	while(lrs.length) ((shft = lrs.shift()).name == sp)
	&& (aL = aD.activeLayer = shft, slctn.selectAll(), slctn.clear(),
	aD.paste(), shft != aD.activeLayer && aD.activeLayer.merge())
}

Okay, my bad. Seems like I wasn't specific enough.

The Green layer called "_ELEMENT_SPECULAR" needs to be replaced with the Red layers called "SPECULAR PASS".
Each Replaced layer needs to contain the following attributes from each individual Red layers.

- Name
- Blending Mode
- Opacity
- Placement
The placement of the New Replaced layer should in the same location as the Old Red layer. As shown in Explanation_02.jpg (See attached).
Preferably the script can replace any layer that is selected but it is also okay to change the name of the layer within the script as I need to use it on "_ELEMENT_DIRECT copy" aswell.

If something is not clear or you need any extra information please let me know. Also use the PSD file in the post for testing.
