+In Godot, it is possible to export 3D scenes as a glTF 2.0 file. You can
 export as a glTF binary (``.glb`` file) or glTF embedded with textures
 (``gltf`` + ``.bin`` + textures). This allows you to create scenes in Godot,
 such as a CSG mesh blockout for a level, export it to clean it up in a
 program such as Blender, and then bring it back into Godot.
