Typically a specular map is a black and white image that maps out the shininess value on an object. What you should see is the specular content where the metallic surfaces are and the diffuse content where the insulators are, which means you have a proper albedo map for the metalness workflow. Can Power be absorbed by large transformers. Can anyone here please explain these maps in 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. 4 * 8 = 32 bits per pixel. Now let select the specular texture and the color mix node duplicate it and place it in the displacement socket, Then we add our normal map as an image texture connect it to a normal map node the connect it to the normal input of the glossy and diffused shader.
