Backup Modifiers earns its spot in the blender_extensions library by handling one task cleanly: applying modifiers while keeping an automatic backup, with buttons to switch between the applied and backup versions. At 3.0 KB with no special permissions, it stays out of the way.
Backup Modifiers adds an apply button to Blender that automatically creates a backup when you apply modifiers, so you don't have to build separate backup collections by hand. From that button you can switch to the backup, edit, and re-apply modifiers whenever you need to.
The add-on exposes three actions. Original switches to the backup object. Applied switches to the modifiers-applied object without updating modifiers. Apply (Update) duplicates the object and applies modifiers, turning the original into the backup object.
Backup Modifiers works with Blender 4.2 LTS and newer and requires no special permissions. At 3.0 KB, it installs by dragging the file into Blender or through Install from Disk, and it's released under the GNU General Public License v3.0 or later. This is version 1.0.4.
Backup Modifiers is best for blender users who apply modifiers and want an automatic backup they can switch back to, edit, and re-apply, without maintaining separate backup collections by hand.
Backup Modifiers is completely free to download and use.
Backup Modifiers is compatible with Blender 4.2 LTS and newer, so any release from that version forward should run it. The extension is small at 3.0 KB and requires no special permissions in Blender. It's currently at version 1.0.4. If you're on an older Blender release, you'll want to update before installing, since versions earlier than 4.2 LTS aren't listed as supported. For the latest compatibility details, check the developer's page on GitHub.
Backup Modifiers installs like other Blender extensions. You can drag and drop the downloaded file directly into Blender, or download it and use Install from Disk through Blender's extension preferences. The download is a small 3.0 KB zip, so setup is quick. Once installed, the add-on adds its apply button and the Original, Applied, and Apply (Update) actions for working with modifiers. This is version 1.0.4, and issues can be reported through the developer's GitHub page.
Backup Modifiers provides three actions. Apply (Update) duplicates the object and applies modifiers, turning the original into the backup object. Original switches you back to that backup object. Applied switches to the modifiers-applied object without updating modifiers. Together these let you apply modifiers, keep a backup automatically, and switch between the two versions so you can edit and re-apply modifiers later. The workflow avoids building separate backup collections by hand, which is the point of the add-on.
Backup Modifiers is listed as free here in the catalog, and it's released under the GNU General Public License v3.0 or later. That license also means the source is available; issues and the code can be found on the developer's GitHub page. The extension requires no special permissions in Blender and weighs just 3.0 KB. For the most current licensing and download details, check the developer's page rather than relying on a fixed figure.
