Texture Set Merger for Substance Painter

haha the problem was solved such way - just renamed .artLayers to .layers in this line (because of groups)
app.activeDocument.layers.getByName(layerNames[k]).duplicate(map1[0],

Sorry dude but this doesn't work for photoshop 2018, it's closing silently each time the mergeMaps method has executing (somewhere near to duplicate method)

Jozin, I haven't had a chance to test this on 2018 yet, make sure your texture set names don't have spaces in them like "04 default_normal.psd" and try again. This will be fixed in the next update.

Also you need to reverse the loop for k = 0 to layerNames.length because of nature of stack (layerNames.push) otherwise it places layers in wrong order

Glad you could make it work, their API changes over time without any fallback. This is really just a hack. Cheers

Thanks Jozin! That works for me too :D

This is awesome! Saves so much time version doing the baking for Multiple Mats in one textureset.

Thanks again!

Thank you very much!

don't work in photoshop 2020

First - how come that you have several materials in the shared UV space? What the point? Just to keep them separated in SP? Second - do not use PNG files, most apps and engines (unity, unreal) hate them.

any way to get more then 4k textures with this?

This actually would benefit the SPainter itself from exporting object materials that has 1 single UV space but are separated by specific UV layer pieces to paint. So that when you export multiple layers of 1 object the materials are combined for that texture set.
In example a 2k sword with separated multipieces: blade, guard, hilt, pommel with 1 UV map. 😞
