7 MATERIALS REFERENCE7.1.25 TireThe Tire material allows you to quickly texture tires and give them a rubber shading.» Tire Material Settings294» 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 manydirections.» Glossy Color: Sets the shader’s colour for glossy reflections. Glossy reflectionbehavior is described by the law of reflection which states that the directionof incoming light (incident ray) and the direction of outgoing light reflected(reflected ray) form the same angle with respect to the surface normal, thusthe angle of incidence 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.
