-Wind animation is controlled by editing the properties on the [[fanvfx|Fan object]] and the wind properties of each generator in the model (e.g., [[branch_generator#​wind|branches]] and [[leaf_mesh_generator#​wind|leaves]]). ​ The recommended procedure is to run the Wind Wizard ("​Tools->​Wind wizard..."​) and then fine tune the results.+Wind animation is controlled by editing the properties on the [[fanvfx|Fan object]] and the wind properties of each generator in the model (e.g., [[branch_generator#​wind|branches]] and [[leaf_mesh_generator#​wind|leaves]]). ​ The recommended procedure is to run the Wind Wizard ("​Tools->​Wind wizard..."​) and then fine-tune the results.
  
 When wind is enabled ('​8'​ hotkey or "​Enabled"​ property on the Fan), the model will animate continuously in the window. When wind is enabled ('​8'​ hotkey or "​Enabled"​ property on the Fan), the model will animate continuously in the window.

-You can edit the animation at any time by changing the properties in the "​Wind"​ group on each generator and on the Fan object. ​ This section provides a high level overview of the process and each general category you'll need to address. ​ For individual property documentation please reference the [[fanue4|UE4 Fan object page]].+You can edit the animation at any time by changing the properties in the "​Wind"​ group on each generator and on the Fan object. ​ This section provides a high-level overview of the process and each general category you'll need to address. ​ For individual property documentation please reference the [[fanue4|UE4 Fan object page]].

 The “Set conditions” menu option on the fan and wind toolbar menu provide shortcuts for setting common conditions like breezy and stormy. These choices set the nominal wind strength and gusting parameters to best match the named conditions. Use these settings to help guide wind tuning for models that will be in the same scene. The Wind Wizard will attempt to set all wind properties such that the model behaves appropriately under all of the preset conditions. The “Set conditions” menu option on the fan and wind toolbar menu provide shortcuts for setting common conditions like breezy and stormy.

 >​**Note**: ​ “Duration” values of 0.0 still have an effect on gusting since the time to rise to the value and fall from it are not counted against the duration. Use 0.0 and low scalars to simulate turbulent conditions. ​ >​**Note**: ​ “Duration” values of 0.0 still have an effect on gusting since the time to rise to the value and fall from it are not counted against the duration.
