@HappyKuTou this area of the code is how obj2gltf converts .mtl to glTF PBR materials: https://github.com/CesiumGS/obj2gltf/blob/79848febe31d3fb5024767c7e8a481728dd491e1/lib/loadMtl.js#L733-L755

Ultimately there's not a perfect conversion from the blinn/phong model to metallic-roughness so we approximated it as best we could. Hopefully this is enough to get started with your converter. I'm going to close the issue since there's no action here for obj2gltf.
