Simplifies materials into two categories, insulators and metals, which may make it more difficult to author content with unrealistic texture values, Uses less texture memory than full color specular workflow, Material transition points cause white line artifacts, Less control over reflectivity for insulators*, If artists do not understand workflow, its easy to use illogical values in metalness map and break the system, Create a new fill layer that is black (#000000), Paste your metalness map into the layer mask of your fill layer, Make a duplicate of the original albedo map and move it above the fill layer, Create another fill layer with a value of #383838.
