Installing Blender add-ons

Blender add-ons are usually installed from a single .py file or a zipped add-on package. Once installed, the add-on still has to be enabled before its panels, menus, or operators show up.

Generic install

1. Open Blender.
2. Go to Edit > Preferences > Add-ons.
3. Use Install from Disk.
4. Choose the add-on's .py file or .zip package.
5. Enable the checkbox next to the add-on after Blender adds it to the list.
6. Use the add-on's article to find its panel, menu item, or operator.

Example from toolbox

Suppose toolbox is cloned at C:\Users\ccn\projects\toolbox and you want to install one of the Blender add-ons stored in it.

1. In Blender, go to Edit > Preferences > Add-ons.
2. Click Install from Disk.
3. Choose a file from C:\Users\ccn\projects\toolbox\content\notes\software\blender\addons.
4. For example, choose better_gltf_exporter_addon.py.
5. Enable Better glTF Exporter.
6. Use File > Export > Better glTF (.gltf).

Notes

• A standalone .py add-on can be installed directly.
• If Blender copies the add-on into its preferences folder, editing the toolbox copy may not update Blender's installed copy automatically.
• When actively developing an add-on, it can be faster to run the script from Blender's text editor, install it again after edits, or place a development copy in Blender's scripts/addons folder.
