material with textures in different UV map channels

[dzhakhangirov]

Hi! I have a problem with processing material with textures in different UV map channels.
When I upload a model to the editor - https://modelviewer.dev/editor/
Everything is shown correctly!
But if I download files using the "Download scene" button and place them on my server, there is a problem with the display - https://arguv.com/ar_viewer/custom/0/bug/UV_map_channels/
3D model - https://arguv.com/ar_viewer/custom/0/bug/UV_map_channels/Sangens_W30S.glb
Can you tell me what the problem might be?

Hi, are you editing the model in the modelviewer editor? If you place the downloaded glb in model viewer editor again, does it show any difference?

Hi! No, I'm not editing the model in the Model viewer editor.
If I load the model again, there is no difference. It's still the same mistake.
As if the editor uses another library, not this one - https://ajax.googleapis.com/ajax/libs/model-viewer/3.0.1/model-viewer.min.js
I attached a link to the model, you can try it yourself.

By the way, if you return the old version of the connection with the file below, then everything works fine!

<script type="module" src="https://unpkg.com/@google/model-viewer/dist/model-viewer.min.js"></script>

Here is the version with the previous script - https://arguv.com/ar_viewer/custom/0/bug/UV_map_channels_old/

It looks to me like the problem is that you're using v3.0.1 when the latest is v3.2.0: https://modelviewer.dev/
