I bought the bundle! for Godot it would be ideal to have the glb files with materials and textures included (i think glb is better than gltf because it includes everything and it should be ready to use in godot, gltf is good for what needs to have different textures), i'm just starting with 3d but i think i'm right. In any case thank you for the bundle it looks really really great at a great price! 

sorry i haven't asked but of course are these assets usable for commercial projects?
