With gloss maps, bright values typically define smooth/glossy surfaces, while roughness maps typically use bright values to define rough/matte surfaces. The metalness workflow on the other hand, uses the albedo map to define both the diffuse and reflectivity content and the metalness map to define whether the material is an insulator or a metal. A dusty rock is going to be very rough, maybe even completely rough, but a smooth rock from a river might actually be pretty polished and pretty glossy. The page you were looking for does not exist.
