As mentioned, the Conceptual Selector is drawn in a separate render scene, which has its own lighting, independent of the drawing. There are three preset light sets available to the user: Ambient, Headlight, Compound headlight. The Ambient and Headlight light sets are the regular ambient and headlight light sources. The Compound headlight set (by default) consists of three headlight light sources, which are not located at the camera center – they are positioned on different sides of the view direction. This provides a better 3D effect when lighting Conceptual Selector. The profile parameters Affect diffuse and Affect specular provide a way to adjust intensity of corresponding lighting components.
