9 MATERIALS REFERENCE9.1.17 ReflectivePlasticMaterialThe ReflectivePlasticMaterial is suitable to simulate shiny or glossy plastic surfaces thatare finished with a clearcoat.» Reflective Plastic Material Settings» Diffuse Color: Sets the shader’s diffuse reflection color. This is the color theshader adopts when the light reflection of the surface is spread to many directions.» Specular Color: Sets the shader’s color for specular reflections. Specular reflectionsresult from completely smooth surfaces and are described by the lawof reflection which states that the direction of incoming light (incident ray) andthe direction of outgoing light reflected (reflected ray) form the same angle withrespect to the surface normal, thus the angle of incidence equals the angle ofreflection.» Reflectivity: Sets the specular reflection intensity when the surface normal isdirectly facing the viewer. The intensity of the reflection increases based on thefresnel term when the angle between the viewer and the surface normal increases.» Fresnel Term Quality: The Fresnel Term describes the intensity of a reflectionbased on the viewing angle. Its intensity at normal incidence is set by the material’sreflectivity.• Fast: Uses a fast but less accurate approximation to the Fresnel Term.• Accurate: Uses a physically accurate evaluation of the Fresnel Term.» Diffuse Texture274» Use Texture:Loads an image texture for the diffuse color channel. Uses the imageas pattern on the surfaces.• Repeat Mode UV: Sets the repeat mode of the texture. There are fourmodes, which can be set:· Repeat: Repeats the texture in all directions. Repeat
