Batch Tool

Batch Tool lists support for Blender 3.2, 3.1, 3.0, 2.93, 2.92, 2.91, 2.9, 2.83, 2.82, and 2.81. If you work across several of these releases, the add-on covers the range from 2.81 up to 3.2. Check the developer's page to confirm compatibility with your specific Blender build before relying on it for a production task, since supported versions can differ from your installed release.

Batch Tool requires basic Python knowledge, because you write your own custom script that performs the fix or operation you want applied. You save that script as a .py file, then point the Batch Tool panel at it along with the folder of .blend files. The add-on itself does not generate the script for you, so some familiarity with writing Python is needed to get useful results across your files.

Batch Tool applies your script to each .blend file, but you need to include a save command in the script itself if you want the changes written to disk. Without it, the operation runs but your modifications may not be preserved. The developer also recommends always backing up your files before running any script, so you have a copy to fall back on if a script behaves unexpectedly across many files.

Batch Tool includes an optional Subfolders setting. When enabled, it includes all .blend files inside subdirectories of the folder you select, not just files at the top level. This option was added in version 1.4. If you keep projects organized across nested folders, enabling it lets a single run reach every .blend file in the structure rather than requiring you to run the tool folder by folder.

Batch Tool is listed as free in this catalog and is released under the GPL license. Pricing and licensing terms can change over time, so for the current details you should check the developer's page directly. There you can also confirm supported Blender versions, read the documentation, and view the demo video before adding the add-on to your workflow.
