 +====== Fan - Lumberyard ======
 +This section details the properties of the Fan object when the Modeler is using the Lumberyard wind algorithm.
  
 +The direction and strength of the wind are indicated in the upper right corner of the [[tree_window|Tree Window]].
 +
 +=====Settings=====
 +The properties in this group control high level wind settings.
 +
 +==Enabled==
 +Use this property to toggle wind on and off in the [[tree_window|Tree Window]].
 +
 +==Strength==
 +This property sets the strength of the wind.
 +
 +>​**Note:​** Most algorithms clamp wind strength to the range [0.0, 1.0]; however, Lumberyard wind strength is unbounded and the strength here corresponds to the magnitude of the wind direction vector in the Lumberyard editor.
 +
 +=====Lumberyard=====
 +The Lumberyard version of the Modeler mimics the [[windly|Lumberyard wind]] algorithm. ​ Set the wind strength to the magnitude of the wind vector in your Lumberyard scene and use the properties in this group to tune the behavior.
 +
 +==Bending==
 +This value corresponds to the main bending value of the vegetation asset in Lumberyard.
 +
 +>​**Note:​** The "​Bending"​ value is not exported from SpeedTree (there is no place to store it in the "​.cgf"​ format). ​ You will have to enter this value manually after you import the SpeedTree "​.cgf"​ file.  All other wind values are stored in the exported file.
 +
 +==Branch Amplitude==
 +Specifies how much the branches can move as a function of wind strength and the blue vertex color. The green vertex color offsets this motion in time.  All materials will have this value set on import.
 +
 +==Edges Amplitude==
 +Specifies how much leaves and fronds can move as a function of wind strength and the red vertex color. ​ All materials will have this value set on import.
 +
 +==Detail Frequency==
 +Specifies how fast edges can move as a function of wind strength and the red vertex color. All materials will have this value set on import.
