Helper Godot 4 addon for my Blender addon which is available on the blender market:
After installing this addon, you'll have easier access to the GLTF Import and Scene Initialization scripts:
NOTE: This project was started before I really understood GLTFDocumentExtension well. GLTFDocumentExtension provides a much better way to parse GLTF files, and .blend file parsing comes natively as a part of Godot's extended pipeline functionality.
This addon performs an "ad-hoc" import by scanning the .gltf file and tagging custom import instructions as metadata on Godot nodes.
I do encourage people to investigate what I've done here to use it as a basis for their own tooling. It is extremely common that folks adopt and adapt tools for their own processes when making videogames.
