I think I know a better way now, I can setup Godot to use Blender project files. Then you can save for instance blender files directly into Godot and instantiate them, by for example dragging them into a certain scene. Seems to work well. Many things are life changed if you edit it in Blender, remove, etc. As if Blender and Godot are one program. Did not tried everything, but many things work. I myself did only try to import and island with PBR, lighting.
