The turbulence node implements a Perlin noise field which can be applied to particles or rigid bodies. The magnitude, frequency, and phase attributes control the random motion induced by the node. The best way to see the effect is to apply the field to a group of particles and try varying the parameters.

frequency, interpolationType, noiseLevel, noiseRatio, phaseX, phaseY, phaseZ

Long name (short name)TypeDefaultFlags
frequency (frq) double1.0outputinputconnectablestorablekeyable
frequency
phaseX (phx) double0.0outputinputconnectablestorablekeyable
x component of phase shift. By animating this, you can see the noise disturbance move along the x dimension.
phaseY (phy) double0.0outputinputconnectablestorablekeyable
y component of phase shift. By animating this, you can see the noise disturbance move along the y dimension.
phaseZ (phz) double0.0outputinputconnectablestorablekeyable
z component of phase shift. By animating this, you can see the noise disturbance move along the z dimension. The "phase" attribute prior to Maya 3.0 was equivalent to phaseZ. Pre-Maya 3.0 files will load correctly with the old "phase" value assigned to phaseZ.
noiseLevel (nslv) integer0outputinputconnectablestorablekeyable
Number of iterations for noise evaluation. Increasing this value will give greater irregularity in the particle motion, at the cost of some computation time. A value of 0 gives the same results as in versions of Maya prior to 3.0.
noiseRatio (nsrt) double0.707outputinputconnectablestorablekeyable
The relative magnitude for each consecutive noise evaluation. Used with noiseLevel.
interpolationType (intr) enumLINEARoutputinputconnectablestorablekeyable
the toggle between linear interpolated noise and quadratic interpolated noise. Quadratic interpolation gives more smooth result, but it's more expensive to evaluate.
