It only can be imported correctly in Blender. That's the issue. It can not be imported in Godot game engine or other online glTF viewers or Windows 3D model viewer. one example here: The glTF I exported with your gdx-glft: https://drive.google.com/drive/folders/1b1d5DEFLxNjQ51YaUUKSpWuDO7nwTsUz?usp=sharing The online viewer I used to import them: https://gltf-viewer.donmccurdy.com/ And the error messages:

1 year ago Thanks. The issue is indeed fixed. But please come back to the other question: do you have plan to add the GlbExporter in near future?

No, this format is not so good (eg. can't share textures with other files, slower loading) so i don't plan to invest time in it.
The files from gltf exporter are not supported by Godot engine and lots of other engines... Every time I have to convert them into glb by some external tools. If this glb exporter is missing, what's the difference between this one and the old fbx-conv work flow?
