All objects around us are created from a variety of materials: metal, glass, plastic, rubber, etc. Materials along with the shape of the object, determine its appearance. In MANU, a material is a set of characteristics that, to a certain degree, affect the display of an object's surface in the game. Materials create greater realism in a scene and describe how an object reflects or transmits light. One game project can contain many different materials. Each material has different uses and property settings.
