Hello, it looks like there might be a bug in GLTF2Export when exporting gltf (glb seems to work okay). Trying to load the gltf will give a “failed to load MESH.bin” error even with the sandbox model viewer. Here is the playground I am using: [https://playground.babylonjs.com/#67EZSP#9](https://playground.babylonjs.com/#67EZSP#9) Loading the exported GLTF on the [model viewer](https://sandbox.babylonjs.com/) throws: “Unable to load from file:cube.gltf: /buffers/0/uri: Failed to load ‘cube.bin’: 0” ---

I saved 2 files from your PG, then dropped them both to the Sandbox, everything seems to be OK. Be sure that you drop all the files from GLTF set. ---

Multiple file download was being blocked and I didn’t notice 😑. Thanks!
