Roughness Map
Roughness Map is a tool in digital design that helps control how light interacts with a surface by defining small-scale bumps and dips. When designers use a roughness map, they can make a surface look smooth like glass or textured like sandpaper, all by changing shades of gray in an image. Lighter areas in the map mean the surface will scatter light more, making it look rough, while darker areas keep the surface looking shiny. This method gives designers a way to add detailed surface effects without changing the shape of the object, which saves time and computer power. Roughness maps are important for showing tiny details like fingerprints, scratches, or fabric weave, making digital materials look more real.
