Metalness defines how metallic your Material is. This can be done with the Metalness factor or a Grayscaled texture
Metalness factor adjusts the metalness between 1 (100% metallic) and 0 (0% metallic).
With a Grayscaled texture, the factor is assigned based on the colour. Black parts are listed as 0 (0% metallic) and white as 1 (100% metallic).
