normal chanel texture transformation is ignored

[orenmiron]

hi
my gltf contains a texture transformation for the normals chanel.
the transformation is ignored by model viewer
in this example, my normals map contains a white polygon.
see snapshots from from khronos viewer (correct) and model viewer (wrong)
normals polygon is marked with red
after all snapshots, I attached the gltf inside a zip file.
please advise

You glTF is invalid, please see the errors reported in our Editor. Let us know if it still has problems once you export a version without errors.

Hi
Attaching a new gltf file without errors.
same question as before: why normal texture doesn't respect transformation.
I also downloaded the master branch and built it - same error
if you can direct me to the source file that load the gltf and where the normal transformation is used, I will try to fix it.
Thanks

This is below the level of our library; you'll need to look at Three.js and their GLTFLoader.js file. Can you repro in their editor? https://threejs.org/editor/

thanks.
it's a three.js problem.
can you recommend a discussion group where i can get support?
Is Three.js sources are on git hub?
