When exporting a file via gltf either in .glb or .gltf, there will be no ior value included in the material info.

Hello,
Currently, we export IOR only when this value is needed for the material (so when you are using one of this other extension:

KHR_materials_transmission
KHR_materials_volume
KHR_materials_specular

What is your use case about wanted to export IOR on a material where IOR does'nt have any effect?
