9.1 Truelight Materials9.1.23 TireMaterialThe TireMaterial allows you to quickly texture tires and give them a rubber shading.» Material Settings» Diffuse Color: Sets the shaders diffuse reflection color. This is the color theshader takes on, when the light reflection of the surface is spread to many directions.» Glossy Color: Sets the shader’s colour for glossy reflections. Glossy reflectionbehavior is described by the law of reflection which states that the direction ofincoming light (incident ray) and the direction of outgoing light reflected (reflectedray) form the same angle with respect to the surface normal, thus the angle ofincidence equals the angle of reflection.» Roughness: The roughness parameter defines the microscopic roughness of asurface. The higher the roughness value, the more diffuse the glossy reflectionswill be rendered.293
