This stored information then canbe quickly and easily accessed for fast switching between different variants either byusing the GUI, hotkeys or by Python scripts.There are three different types of variants: geometry variants, material variants andlight variants. A geometry variant is linked to a node in the scene graph, with eitheris a normal node which can be enabled or disabled or which is a switch node whichselects only one child for rendering at a time. In the same manner a switch materialis a container for one or more materials, and only one of these is active duringrendering.
