[DRACO] GLTFLoader and multiple materials on single mesh with one UVmap

Is that supported? Im having problem with my glb objects.
Im using:
threejs 107dev,
blender [ 2.82 (sub 7), branch: master, commit date: 2020-02-12 16:20, hash: 77d23b0bd76f, type: Release
build date: 2020-02-13, 01:56:46]

So when I use GLTF with multiple materials im getting that error on all of my objects that use more than one material
Heres one of my objects with one and second one is with two materials to compare
whales.zip (100.3 KB)

They both seem to work fine in https://gltf-viewer.donmccurdy.com/… do you get the same result with a recent version of three.js? I’m not sure what r107dev means, are you not using a stable release?

propably yes, becouse i had many problems with stable ones back when i started my project. I tried to go r114 but it seems that i need with that fix many other new errors :\ So it requires time to upgrade and god knows if there are any new problems with newer versions :expressionless:
Maybe its just becouse im unexperienced with js. Lets say im learning js thanks to threejs haha

Anyways… stupid question :stuck_out_tongue:

I’m not sure. I don’t know of any reason that an off-release version around r107 wouldn’t work either. But I won’t be able to reproduce that without a demo, and I have no idea what to make of the error message. Also make sure that your GLTFLoader and DRACOLoader files are from the same versions of three.js.
