After this the dialog should look something like the following: Select OK and a new image is created and should look like the image below. The reason for this is simple, insulators tend to have uncolored reflectance values around 4% linear (or #383838 sRGB), with min and max values generally in the 2-16% range (though few insulators other than gemstones are > 4%), while pure metals have much higher reflectance values, generally in the 70-100% range. By - June 3, 2022. Thus, figuring out exactly what type of material youre representing is very important when it comes to finding the right reflectance value. Specular maps are used to define the shininess/highlight on a surface. Pull the black slider in towards the center until you start to see some white speckles appear in the texture. The tutorial slices this image further, but since the GIMP Image Map Plug-in and image maps in general use coordinates, we can use a less complicated table forthis. This means the specular map had to do double duty trying to represent both reflectivity and microsurface, while using a uniform glossiness value for the entire material. Everything has reflectivity, even they are standardized into 2 major categories.

Glossiness This map is the inverse of the roughness map. This map should be fairly flat with no baked in AO/Shadows. Undo and repeat changing. For instance, metals are much more reflective than insulators, rubber is generally rougher than plastic, concrete typically has a brighter albedo than asphalt, and so on.

On the left panel, click the in any of the empty boxes. 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.
