Characteristic Graph Shows a stylized graph of how changing Noise properties
affects the Noise curve.
Seed Starts the noise calculations. Changing the seed creates a new curve.
Frequency Controls the peaks and valleys of the noise curve. The useful range
is from 0.01 to 1.0. High values create jagged, heavily oscillating noise curves.
Low values create soft, gentle noise curves.
Strength fields Sets the value range for noise output. These values can be
animated.
The number and meaning of the fields vary with different parameter data
types. Some typical field arrangements are:
■ XYZ fields for Position and Point3 keys
■ XYZ percentage fields for Scale keys
■ A single value field for Float keys
>0 Value constraint Forces Noise values to stay positive. Each strength field
has its own >0 constraint.
When on, the application of the Strength field is changed. Noise values will
range from 0 to the value of Strength; most values will hover around
Strength/2.
