[SOLVED] Problem with loading compressed glb-File

Help & Support
1

Building my own model-loader I’ve stumbled across the following issue:
I’ve exported a model from blender to .glb using compression:
https://xpe.at/testfiles/models/mercury-statue_05.glb

and without compression:
https://xpe.at/testfiles/models/mercury-statue_06.glb

Using the gltf-viewer both objects work, see:

Using the gltf-Loader example it did work with the uncompressed file, but not with the compressed one.
See:
https://playcanvas.com/editor/scene/1611735
(the glbUrl is currently set at the not working https://xpe.at/testfiles/models/mercury-statue_06.glb)

Is there something I’m missing?

Thanks for any heads up

Is it draco compressed?

I used Blenders internal export tool, as far as I can tell,
this is indeed Google draco compression, checking here:
https://docs.blender.org/manual/en/3.4/addons/import_export/scene_gltf2.html#compression

I assume, this is probably not supported using glb-utils?
If I have to stick to uncompressed, that’s no deal-breaker, I was just wondering as the glTF Viewer was able to load the compressed file.

If its Draco, you will need the WASM runtime here Loading Draco Compressed GLBs | Learn PlayCanvas

Perfect!
I’ve added the runtime, and it now works perfectly!
Thanks for your help!
