Unable to write GLB with 0 buffers
See original GitHub issueMy use case is web and I want to export to .gltf/.glb files.
I’ll do that via simply downloading through the browser. I can handle that part, but it’d be helpful of the library to handle the rest (converting the Document to ArrayBuffer for glb, and a JSON string for the gltf).
Not sure how to do that with the current state of the library.

I’m not quite sure how best to export a file like this; asking for clarification in https://github.com/KhronosGroup/glTF/issues/1975.
Your code looks right, does including
document.createBuffer()fix that error? I believe the GLB export does require a buffer, which might be a bug in the library, it’s just unusual in this case because normally there would be vertex data or textures with binary data, and the camera doesn’t require any.I’ll look into this more in a bit!
