Different pbr-material/look results when using .glb/gltf compared to ,obj

Can this really be true? I compare same same model, one time loaded as .obj, one time as .glb, both getting the same texture maps for map, roughness, metalness and normalMap, both under the same lightning conditions aso, but, the result looks different… ?


Well, since a OBJ has no material definitions, you have to setup instances of MeshStandardMaterial in the correct way so you can compare the results with glTF. Please share a live example that demonstrates how you do this. There is probably something wrong with your material configuration.
