So my idea was to use same format/medium for inspecting and changing simple 3d shapes between Blender and Godot. I wanted to have a single file.
Exporting and saving is exactly same thing, but somehow Godot still separates and makes workflow harder in the long-run.
It is possible to export GLTF files as scenes, then why it’s not possible to simply save?
You can export scenes as gltf files. More info here Exporting 3D scenes — Godot Engine (stable) documentation in English
The key issue is that Godot’s scene system is fundamentally different from 3D modelling workflow. In Godot, .tscn and .scn files store scene-specific data, while GLTF is more of an interchange format.
You can have one .gltf file with all meshes necessary for you. And update (reimport) it.
