NEW IN R20
Use this setting to define the color of the concrete. Concrete will most often be colored a particular shade of gray.
The Turbulence setting can be used to add light streaks across large areas of the concrete. Smaller values will disable the effect, larger values will increase it correspondingly (this also applies to the next two settings).
This setting can be used to create a fine grain structure, e.g., as with exposed aggregate concrete.
This setting can be used to disperse dark spots across the concrete.
