This value scales the wave function in the Z direction, and the turbulence function in the Y direction. To change the value interactively, drag the orange handle on the Z axis.
This value scales the deformer in the X axis and Y axis. Increasing this value will have the effect of increasing the frequency of the waves. If the Flag option is checked, Size will also cause a more abrupt change in the size of the X axis envelope.
The frequency determines the speed of the waves.
This setting adds secondary waves in the X direction, with amplitude in the +Z direction. In addition, Turbulence adds a wave in the Y direction, with amplitude in the +Z direction. The percentage defines the size of these secondary waves relative to the main waves.
These values determine the frequency of the waves in the X and Y directions.
If you enable this option, all points along the deformer’s Y axis remain still (fixed). For example, you can use this to simulate a flag on a pole — one end of the flag flaps freely in the wind, while the other end is fixed to the pole and does not move (place the deformer’s Y axis along this end of the flag).
