Returns the roughness of the turbulence.
@returns The roughness of the turbulence.
The roughness of the turbulence determines the roughness of the changes to the displacement amount. Low values smoothly change the displacement amount. High values roughly change the displacement amount, which produces more "kinky" changes.
