Switch
A switch material can contain several materials, but only one of them is visible at a time. Environments cannot be added to a switch material, only to an environment switch material.
Video captions: Create a switch material and assign it to a geometry. As an aid, select the car paint material that is already assigned to the geometry. Upon calling up the Material Editor menu with the right mouse button, pick Select Nodes. Assign the switch material to the geometry by running the command, Apply To Select Nodes. Duplicate the car paint material multiple times and change each diffuse color as you feel. Subordinate the created car paint material via drag and drop to the switch material. Within a switch material, multiple different materials can be integrated and selected between them. The currently selected one is active, while all others remain inactive. The order of the materials can be changed via the command, Move Up and Move Down, after invoking the Switch Material menu with the right mouse button.

Assigning Multiple Material Variants to a Switch
To assign several material variants on creation, select them and then select Create Switch from Selection from the context menu.
Attributes
When a switch is selected, its material variants are listed in the Attributes and Choice pulldown. However, if they aren't, click the section title. Adding a check next to a material variant makes it active, as does choosing one from the Choice pulldown, which defines which entry of the materials in the list is set to active.
Double-click a material variant to load its properties and click the switch tab to return to the switch and list of material variants.
Context Menu

Select Material (Ctrl+N) - Use for loading the properties of the switch's original material into the Attributes. With a switch selected, right-click one of its material variants and select Select Material to load the original material properties, not those of the material variant.
Paste (Ctrl+V) - Adds the copied material to the switch.
Delete (Del) - Deleted the selected child material from the switch.
Move Up (Ctrl+PgUp) - Moves the selected child material up in order, switching it with the one previously before it.
Move Down (Ctrl+PgDown) - Moves the selected child material down in order, switching it with the one previously after it.
