The MaterialThe representation of the surface or volume properties of an object. Switch node has inputs that can be connected to other materials and provides an Input parameters to switch between the connected materials (figure 1).
Figure 1: The Material Switch node use to switch between a Diffuse materialUsed for dull, non-reflecting materials or mesh emitters. and a GlossyThe measure of how well light is reflected from a surface in the specular direction, the amount and way in which the light is spread around the specular direction, and the change in specular reflection as the specular angle changes. Used for shiny materials such as plastics or metals. Material
