hello，I export a glb file from unity scene,it can't import in blender.I found that this file has entensionsRequired KHR_materials_pbrSpecularGlossiness.Can I export a glb model without the KHR_materials_pbrSpecular Glossiness extension?

Yes... Dont use Standard Specular (or any Unity shader with specular glossiness workflow).

Stick to the Standard shader. That uses the GLTF 2.0 Default Metallic Roughness workflow the specular extension is not needed

I just deleted some mesh, so I can import Blender.Do you have an email? I can send you these two files, they both exceed 25MB. Also, is there a way to obtain the source code for UnityExporter? I only need the 2022.3. X version. I have some good ideas about lighting baking to web pages, and I have also obtained some model data by restoring GLB to GLTF myself. I want to automate the entire process. In addition, for Draco compression of the model, I developed a desktop application to compress the model, including compressing textures(More precisely, it is cutting the texture to a certain size).

Can you give me some help? Thank you.
