There are two methods of installing and enabling the glTF 2.0 Blender exporter. In either case, you must first download the exporter and unzip it.
Option 1: Copy into scripts/addons
After extracting the ZIP, copy
scripts/addons/io_scene_gltf2 to the
scripts/addons folder of your Blender installation.
Next, enable the exporter.
Option 2: Configure user scripts directory
After downloading the exporter, open the
User Preferences... dialog in Blender:
Go to the
File tab and set the
Scripts directory to the
scripts folder from the downloaded ZIP:
An advantage of this option is that changes to the exporter are automatically visible applied in Blender. However, the
Scripts folder is no longer available for other extensions.
After installing, you must enable the exporter.
Enable the exporter
You must also enable the glTF 2.0 exporter under the
Add-ons tab. If you have another glTF 2.0 exporter installed, only one may be enabled at a time.
