Custom node for animated noise (random values). By default random values are generated between -1 and 1 but maybe multiplied by amplitude and offset attributes.
smoothing - smooths generated values default: 0.5 (range 0 to 1)
offset - offsets generated values - default: 0.0
amplitude - multiple to apply to generated values default: 1.0
frequency - Multiplies frequency of randomness default: 1.0 (range 0 to 1)
seed - value changes random pattern default: 1
rectify - Inverts negatives values. default: False
wave - Maya optionally generate sine waves instead of noise. default: Noise output - resulting random values
phase - sets phase of sine wave or offsets frames of noise
