Map types increase the complexity of a material.
Within each map channel (Diffuse, Reflection, Opacity, and Bump). You can select texture or procedural maps. Using map types can increase the complexity of a material.
Map types include the following:
Each map type has its own specific set of map controls. Within each Map Channel you can control settings, such as disable a map, delete a map, or synchronize a map. You can select the Map Synchronize toggle button to disable/enable the settings and value changes of the map channel to be pushed and synchronized to all map channels. By the default this toggle is set to enable. It is enabled when the icon is combined. It is disabled if is separated
The display will give a you Quick Reference to the nested maps assigned to a material. You can select the drop down arrow next to the name of the material and the nested maps assigned will be displayed.
After you apply a map type, you can adjust it to fit on a face or object by using material mapping.
