Hello, Im using a 3D model of GLB type, it is a human, but however, Three automatically applied very plastic-looking reflection to it, it looks smooth and shiny, which I really do not want. I tried using material.shininess, but that only broke my code, anyone knows how to apply a… well… “humanish” reflection?  
Thanks

This property only exists for `MeshPhongMaterial` which is not used by `GLTFLoader`. You want to work with the properties of `MeshStandardMaterial`.

Without seeing your model and a screenshot that shows the expected result it’s hard to give you a specific advice. But I suggest you set `roughness` to 1 and `metalness` to 0 as a start.
