Unable to upload 3D model
Hello, everyone.
I'm trying to upload a 3d model, I'm trying to do ar/vr try on feature for my product, but I've been unable to get it to work,...
Error message is reported:
{"feedback":{"Asin": "B07KCSTZ4G", "ProcessedTime": "2023-10-11T01:00:59.764+0000", "PackageErrors":{"INVALID_CONTENT": "Unsupported extensions found: KHR_materials_specular"}}}
I've reworked this many times with our 3d designers and it still doesn't work, do you know what to do?
If anyone knows how to fix this please let me know, I would appreciate it!

Hi @Seller_jFPp2m2uagEGT, I found this help page on uploading 3D content - additionally, have you reached out to Seller Support for more context on the error message you received?

@Seller_jFPp2m2uagEGTWhat was the resolution for this issue? I get the same error after uploading the model!
I am using Blender and exporting the model to .glb format
I went trough the technical documentation on support page and also validated our model through suggested Khronos validation tool ("The asset is valid")
I can open, rotate and interact with the model in "3D aset preview" tool inside sellers central
I tried reaching out to support (case ID 14151720741) but I receive same canned answer with upload steps and tech docs page mentioned above
@Glenn_AmazonIf you could help me in any way, it would be very much appreciated.

Okay so after some back and forth with seller support, I was able to understand what is the nature of the problem is:
You must NOT include specular material in export
Here is quote from SC:
"the system rejected the the model because it uses the KHR_materials_specular shader, which is incompatible with our 3D viewers of AR and 3D experiences. Please remove the shader and re-upload the asset.
Also, KHR_materials_specular – only necessary if you want colored reflections/highlights (not at all required here – the values assigned would just make highlights more dull/grey)."
The problem is when you exporting glb from Blender it does not have an option not to include specular extension.
So, here is working solution I came up with:
Export from Blender → open in "glTF Editor" (Google glTF Editor - Edit, View and Convert glTF & USDZ files) and then export again (file→save)
Now if you go to the "Khronos validation tool" you won't see "KHR_materials_specular" under "extensionsUsed" and Amazon's validator will let the file go through initial checks
