Materials define every aspect of the surface including color, reflectivity, bumpiness, transparency, and so on. These calculations are done using data that is input to the Material from a variety of images (textures) and node-based Material expressions, as well as from various property settings inherent to the Material itself.

			The Metallic input controls how 'metal-like' your surface will be. Metallic accepts any value between 0 and 1, but in a majority of cases Metallic is considered an either/or property.
			Nonmetals have a Metallic value of 0.
			Metals have a Metallic value of 1.
			For pure surfaces, such as pure metal, pure stone, or pure plastic this value will be 0 or 1, not anything in between. When creating hybrid surfaces like corroded, dusty, or rusty metals, you may find that you need some value between 0 and 1.

			'''Specular'''
			Specularity is a measure of how much light a surface reflects. The Specular input takes a value between 0 and 1, and defines the extent to which a surface is reflective:
			Value of 0 - Fully non-reflective
			Value of 1 - Fully reflective
			The default value is 0.5, which represents approximately 4% reflectivity.

			'''Roughness'''
			The Roughness input controls how rough or smooth a Material's surface is. Rough Materials scatter reflected light in more directions than smooth Materials. This value controls how blurry or sharp a reflection is (or how broad or tight a specular highlight is).
