UnityEngine.WindModule The Wind module implements the WindZone component which can affect terrain rendering and particle simulations. Wind Zones add realism to the trees you create by making them wave their branches and leaves as if blown by the wind. Defines the type of wind zone to be used (Spherical or Directional). Radius of the Spherical Wind Zone (only active if the WindZoneMode is set to Spherical). The primary wind force. Defines the frequency of the wind changes. Defines how much the wind changes over time. The turbulence wind force. The constructor. Modes a Wind Zone can have, either Spherical or Directional. Wind zone affects the entire scene in one direction. Wind zone only has an effect inside the radius, and has a falloff from the center towards the edge.
