System Information
Operating system: Mac OS
Graphics card: Intel

Blender Version
Broken:

3.3

Worked:

3.2
Short description of error

both 3.3 and 3.4 have a model importing issue. Both obj and glb can't be imported properly. The symptom is that the material looks very dark and can't be rendered with the correct color. As you can see, the specular color is -inf.

This doesn't happen with 3.2

Exact steps for others to reproduce the error

Unfortunately I can't share the model. But you can request for access from here https://tianchi.aliyun.com/specials/promotion/alibaba-3d-scene-dataset

Hi, thanks for the report. We won't be able to investigate this without knowing a way to reproduce it. Also, not sure where exactly the file is located on website. Can you upload obj/glb file directly here?

there is a download button on that page. through that button, you can find the download link https://tianchi.aliyun.com/dataset/65347. you will have to register and they will approve in a day.

I'm sorry, the data come with a term that I can't share them with you directly.

But I may be able to create a simple cube that reproduces the issue. But that will take sometime.

Can you test on a more recent Blender, eg. 3.6 Alpha? This may be the same as https://github.com/KhronosGroup/glTF-Blender-IO/issues/1838, which is fixed.

@billconan hi, Have you checked yet in recent 3.5/3.6 build?: https://builder.blender.org/download/daily/
