Roughness maps are a great way to add extra detail and variation to your textures. The black lines in between are only one pixel widealso. Save the data as a new image in XCF format. Roughness is a 0-1 value that determines the microfacet roughness of a surface- e.g. Thus, figuring out exactly what type of material youre representing is very important when it comes to finding the right reflectance value. Hold CTRL to select multiple ones and you can do transforms etc aswell (right click, free transform points). The reason for this is that metals conduct electricity, which means that most photons (which are electromagnetic waves) reflect off the surface, and any photons that pass through the surface are absorbed rather than diffused, so metals typically do not have a diffuse component. This is a screenshot of the Create Guides Dialog (left image). Then drag Opacity onto the A channel and choose Gray Channel from the drop-down.
