Converting to *Linked* Smart Object?

  • November 19, 2022

Hello all,

 

I'm looking for a way to convert layers to a *linked* smart object without having to, first, Convert to Smart Object, and secondly, Convert to Linked... Does anyone know if this is a possibility?

 

Thank you for any help 🙂

Enid

This version will create linked smart object layers for all selected "normal" top-level raster layers and layer groups. The linked SO PSB files will be automatically saved to the same path as the parent file (this could be changed to a sub-folder if more convenient for file management). A single undo history step is provided.

@Enid27216724xdpg – Let me see if this can be automated via scripting...

    The following script will create linked smart object layers for all "normal" top-level raster layers and layer groups. The linked SO PSB files will be automatically saved to the same path as the parent file (this could be changed to a sub-folder if more convenient for file management). A single undo history step is provided. I'll look into making a version for selected layers only.

    1. Copy the code text to the clipboard
    2. Open a new blank file in a plain-text editor (not in a word processor)
    3. Paste the code in
    4. Save the text file as .txt
    5. Rename the file extension from .txt to .jsx
    6. Install or browse to the .jsx file to run (see below):

      No, they are the steps you need to take - with the exception of directly placing an external document as a Linked Smart Object.
