I draco-compressed a mesh using gltf-transform and now I’m getting errors thrown when I try to import it to my scene (uncompressed version works): [image] and here’s that unnamed function (not really sure what this file is): [image] Oddly enough, this GLB works in the sandbox and the playgroun…

After debugging BabylonJS’ core I discovered that using “.glb” was right and it was using the correct loader (glTFLoader ), but there was a version mismatch in babylon’s imports causing a function not to be found, namely, _decodeMeshToGeometryForGltfAsync()

Hmm, unfortunately adding import '@babylonjs/loaders/glTF/2.0/Extensions/KHR_draco_mesh_compression'; to the top of my file did not work. The error that post is discussing is also different than the one I am getting, I believe my code does have access to the extension already.

I managed to load the file with LoadFile() from @babylonjs/core, but then trying to decode the Draco mesh I got “Not a Draco file.” even thought the file is indeed a draco-compressed glb mesh and it loads ok in the playground. …

Here is the PG example with Draco mesh loading from blob - https://playground.babylonjs.com/#FIWM5X#45
