Relink to new resource folder , not each file one by one.

Yeah. it works perfectly. Thanks again Stephen . Not sure why oother day it asked me to point  to each file manually.  I mixed it it with eralier one probably .

You are the  best  help  here 🙂 

In my test the script loops over all layers and groups and nested groups. So all you need to do is select the new folder or paste in the path and all links with the same name will have the new path. So I'm not understanding your problem.

I try to use Photoshop as a sort of 3d render compositing soft   for game assets . It's usually a doesen of AOVs, masks  and render layers  from Blender  I need to relink to a new version of render, like other camera  renders or a new scene.  It's still too many manual selects and I do select wrong image sometimes with your script.       The  one chatGPT did for me  does it all at once with a single click  . I just have to keep all render layers in the main stack  ungrouped  somewhere bellow  actual compositing and work with thier copies.

   Nevertheless thank you very much  for your script . It's still helpfull when I need to relink just a couple of things.

So how does my latest 1.1 script work for you?

Thanks Stephen_A_Marsh .       Here is a test file and two folders.    The script chatGPT made me works only if selected   linked smart objects are not inside a group  . It makes it useless for me actually since I need it to work for clipping group stacks .  Although I love how simple it works with just a path box and copy paste  from file manager .  

ps. well . not totally useless  since you can keep it in main stack ungrouped  somewhere below    and linked copies inside clipping  groups . But too many conditions to follow indeed.       Surprised it works at all .

Here is a code chatGPT made me and it sort of works for me.    You have to have file name and extention be  in linked smart object name   and you have to input the path in a box  with  \  simbol  in the end . You need to add  it  if you copy the path from windows file explorer   and doesn't when copy the path from total commander .

The problem is all the selected  linked smart objects ( it works for selected ones)  should be  visiable  , with eye symbol  on and I need it to work for ones with eye off too.     ChatGPt looks like unable  to do it.   

Could somebody modify it  for working that way please.     

ps. contrary to what first line says it could be any file type not only tga and I have no idea why it makes temporary layer

I wrote the first script. Selecting the folder via a GUI seems less prone to error, but it could be easily changed to a prompt where you paste a path. It should loop over all top level layers and update the link. Can you share a sample file or a screenshot of the layers panel? Do you have nested groups or artboards?

Thank you very much Stephen .  The first one sort of works  but you still have to do manual  job  by  finding folder and selecting  files one by one.   Better than  default way for sure .  The second link  doesn let me point target folder even if  I choose "select target folder ' from drop down .

Would be cool if it was just  copy/paste the path to some input box   and all

Maybe sombody could write a script  that can do it ?
