I used to export 3D models to gltf file for usage within Godot engine. Since Godot exporter stopped being updated I had to create some Python scripts to get file ready for Godot.

I realized that blend file works pretty good "out of box", so I'm thinking about using it primarily. My questions would be how clean is it? Will parts of blend file I'm not using (brushes, images or actions without users) be included into final build?

Does that affect loading time or build size?

    This is a good question and I'd also like an answer to it.

    Everything is described in the documentation — it is better to use glTF:

    • glTF 2.0 (recommended). Godot has full support for both text (.gltf) and binary (.glb) formats.
    • .blend (Blender). This works by calling Blender to export to glTF in a transparent manner (requires Blender to be installed).

    By running glTF export from Blender, you can control this process.
