Base

Color

Use this setting to define the base color of the metal. For steel, this will most likely be gray, for copper a reddish color and so on.

Grain [0..100%]

Different values for Grain and Roughness.

The Grain setting superimposes a scaled-down Noise effect. Effects such as a hammer hit can be created. Small values will disable the respective effect, larger values will strengthen the effect correspondingly.

Roughness [0..100%]

This setting can be used to define the roughness of the metal surface. Smaller values will create a correspondingly more polished look and larger values will cause the surface to look increasingly more matte.

Dirt [0..100%]

Here you can define values larger than 0% to add an Ambient Occlusion effect, which can be used to simulate dirt in ridges and scratches.
