To enhance the realistic appearance of objects, reflection from environment lighting can be created on the object surface. The reflectance color element serves to set the color and the reflection intensity of an active object. The reflectance depends on the environment lights and the viewing angle. The reflectance color can be set by the color constant or compound color components to color elements. The amount of reflection is determined by the dimness element. By setting the dimness to 0 and by setting the reflectance color to black the reflection will be switched off.
