To increase realism, roughness textures can be applied to add minor surface defects or grime such as skin oils, light abrasions or even dust. Using roughness textures in KeyShot can save you from separating surfaces that will have more of a glossy or matte finish on your products. Grayscale values will be respected, such as 50% gray resulting in.

Black values represent a roughness value of zero (glossy), and white values represent roughness value of 1 (matte). KeyShot allows you to take roughness a step further by using texture maps to define roughness. A surface with little or no roughness concentrates the reflected light, giving us sharp reflections and highlights on a surface. The same amount of light is being reflected from the surface, but adding roughness diffuses that light across the surface. When roughness is increased, light that reflects off that material scatters at varying angles, resulting in a more satin or matte finish.īy increasing roughness, a surface will become less glossy and more matte. When roughness is set to zero, light simply bounces off that material at an inverse angle (like a mirror). Roughness is not a bump texture.įrom left to right, the above spheres have a roughness of 0-90%.

In CG, a bump texture is what drives the simulation of varying height of a surface. Rather than modeling a highly intricate texture such as leather or wood grain, we rely on texture maps in KeyShot to add realism to our renderings without having to painstakingly model every intricate detail. The result of using bump textures is an appearance that the detail was modeled into the geometry. The peaks catch light and cast shadows while the valleys recede and reflect very little light. In the CG (computer graphics) world, a bump texture is a grayscale image that simulates peaks and valleys on the surface of geometry. Many assume Roughness and Bump are the same thing but did you know they are two completely different material properties? We often rely solely on bump textures to enhance our materials in KeyShot but the same texture maps you've been using for Bump can also be used for Roughness! Let's take a look at the difference between roughness and bump, to better understand how they can be used to enhance the detail and realism of your renderings in KeyShot.
