A BLEND, COLLADA, FBX and OBJ to GLTF2 converter using Blender and glTF Blender Exporter.
Based on the ideas of 2gltf2 by Norbert Nopper. I wasn't able to get their repo working on MacOS and it was missing installation instructions.
Please note that the current version is highly experimental. Do not use this in your production workflow as of now.
Run blender -b -P gltf-converter.py -- <input> <output>. A .gltf file and a .bin file will be written.
Installation instructions can be found on glTF Blender Exporter Scripts.
Install Blender and drag to the Applications folder. On install a binary should be written to /usr/local/bin/blender that can be verified using which blender.
Open Blender and see if it starts correctly. If you do these adjustments before opening Blender you will likely run into a verification hash issue that MacOS does on every install.
Copy io_scene_gltf2 from glTF Blender Exporter Addons.
Select Blender and right click show package contents -> Contents -> Resources -> 2.79 -> scripts -> addons.
Place io_scene_gltf2 in there. Open Blender -> File -> User preferences -> Add-ons tab -> Toggle on Import-Export: glTF 2.0 format > Save user settings > Refresh.
You should now be able to export scenes as glTF from the dropdown menu File -> glTF 2.0 (.glb) and glTF 2.0 (.gltf).
Remove the default cube scene by following the instructions otherwise you will have an extra cube in your export.
To validate the exported .gltf and .bin, select both (include textures if your model has them) and drag and drop them into the glTF Viewer.
