Displacement

SHADER TYPE: Rough

Rough is a displacement type that can be used to represent rough, wavy material. The roughness continues three-dimensionally through the entire object that the material is placed on. This shader type is suitable for representing rough materials such as cast metal.

Parameter: Explanation: Default value: Possible values and comments:
Scale Scale factor 1  
Amplitude Amplitude of surface noise 0.1 0.0–1
Sharpness Noise sharpness factor 3 At low values such as 1, the surface shapes are sharp. Higher values such as 3 or 4 soften the boundaries.
Detail Noise diversity factor 1 1–6, highest value yields the most diverse result
