Density defines a probability threshold for the random computation. If the density is 0.1, only 10 % of evaluations produce a value other than the random base value. If the density is 1, all evaluations of the object compute a random value.

Base value defines the value, which is output if the density threshold is not triggered. It also defines the base level for random values.

Amplitude defines how much values range from the base value. If the base value is 2 and range is 1, the random values vary between 2 and 3 (when Centered is cleared).

1D values option selects 'gray scale' output: all output sub channels get the same random value.

Centered If set, Amplitude varies symmetrically around the Base value. If cleared, Amplitude is added to the Base value.
