Extension Licenses

For add-ons and themes the recommended license is GNU General Public License v2.0 or later. For assets, the required license is Public Domain (CC0).

The Blender Extensions Platform only supports free and open source extensions compatible with Blender's license: GNU General Public License v3.0 or later.

This allows extensions to be packed with Blender and distributed in compliance with the governing principles of the Blender license.

• GNU General Public License v2.0 or later

• GNU General Public License v3.0 or later.

• GNU Lesser General Public License v2.1 or later.

• GNU Lesser General Public License v3.0 or later.
