Wind On [Animatable] Defines whether the wind forces are applied or not.
Wind Speed [Animatable] The strength of the wind force. The direction is
specified by the icon's orientation, which is also animatable.
Perturb Speed When on, the strength of the wind varies over time, using the
following parameters.
■ Variance The maximum amount of change in the speed.
■ Time Scale How quickly speed change occurs, with small values producing
slow changes, and large values producing rapid changes.
Ripple [Animatable] When on, the wind direction becomes a function of
space and time, allowing you to add rippling effects to cloth objects affected
by the wind. This effect can occur in the Left/Right, Up/Down, or Back/Forward
directions, where Forward is the wind direction and Up is the up-axis of the
wind icon.
■ Magnitude The directional variance for the ripples.
■ Frequency The regularity of ripple formation.
■ Perturb Time When in, the spatial perturbation is itself perturbed over
time, meaning that the ripples move back and forth. The Perturb Time
feature has its own Magnitude and Frequency parameters. When off, the
rippling cloth should eventually come to rest, unless Perturb Speed is on.
Use Range [Animatable] When on, the wind effect has the specified range of
action, starting from the icon. The range limit is displayed in the viewport,
as depicted in the following illustration.
