TypeError: Cannot read property 'array' of undefined about gltfjsx

should be fixed! at least banana.gltf goes through. the draco thing for some reason still doesn't. but you can at least keep on working, the output structure between the two would be the same.

the other error should be gone too. it kind of sucks, gltfloader doesn't work under node and im basically just ripping out all the pieces that crash. i don't need it to actually create buffers, i just need the structure from it - there's probably an easier way: @donmccurdy

1.0.5: also fixed support for bones. it will add the root bone as a single raw primitive and wire up the skeleton of the skinnedmesh. it works ootb, here's an updated example (Stacy.js): https://codesandbox.io/s/r3f-bones-3i7iu

not 100% sure if that's the right way. previously it would put all the bones into proper jsx, but they wouldn't function. looks to me like skeleton is, once again, imperative. 🙈

const skeleton = new Skeleton(bones)
mesh.bind(skeleton)

that's a tragedy as it kills declarative usage.

I've hacked around the nodejs issues before, but it took hacks all the way down. Draco is the hardest part — and that link is outdated, in that regard — because it now uses Web Workers. Open to ideas on improving nodejs support.

Do you just need the JSON from the glTF file? Or the exact threejs object hierarchy that GLTFLoader would return?

[donmccurdy]

If the JSON is enough, I can share how to decode that from a .glb easily.

If you need a full threejs hierarchy, which would be the same as the glTF JSON plus some added leaf nodes, I'm guessing mrdoob/three.js#18484 might help you out — write a plugin that "provides" all the buffers and textures with empty data, let the rest run normally.

i think it would need to be the object hierarchy. i think relying on pure gltf would be the easiest when it comes to reading out, but emulating a basic threejs structure is probably going to be very hard.

the current workflow is based on the /bin directory in this repo, a fork of the loader and everything that ever wants to fetch requests for assets or create things that node can't is removed little by little. i think i oriented myself around the gist you posted, i saw it in the threejs discourse forum i believe. unfortunately i must have minimized it in the very beginning, very clever ... 🤭
