Clean Undo: Disable "Context Set" from Undo

Version 3.1

Author: Gabriel Moro

What it does

This add-on keeps Blender from adding "Context Set" entries to the undo history when switching Render Result slots with the number keys. It helps keep the undo list cleaner and focused on actual edits.

How to Install

1. Open Blender and go to Edit > Preferences.

2. Open the Add-ons tab.

3. Click Install... and choose the ZIP file.

4. Enable Render: Clean Undo: Disable "Context Set" from Undo.

How to Use

1. Open the Image Editor.

2. Set the image to Render Result.

3. Press keys 1 to 8 to switch render slots.

4. The add-on prevents those slot changes from cluttering the undo history with "Context Set".
