What is Roughness?

Roughness is an important parameter when it comes to 3D visualization. It is a measure of the irregularities on the surface of an object, and can have a big impact on the way light interacts with that object. A high degree of roughness will make an object appear duller, while a low degree of roughness will make it appear shinier.

Roughness can be controlled through a number of different methods, including the use of textures, bump maps, and displacement maps. By carefully controlling the roughness of an object, you can create very realistic visuals. Roughness can also be used to add artistic flair to an image or scene. By intentionally making an object appear rougher than it actually is, you can add a sense of drama or tension.
