By default, a ‘Calm’ wind preset will be applied to all models in the scene (in the editor). To change the wind settings you can add a ‘Global Wind’ component to a Game Object in your scene. You can then tweak the wind settings in this component, or load a preset to apply it to the objects in the scene.
When making a build, a Global Wind component is required for the correct wind settings.
(In older versions of Nature Renderer terrain details do not render if there is no Global Wind component in the scene)
Select a Wind Zone from Unity in the ‘Source Wind Zone’ property to copy its settings.
