How strong the wind is (0.0 to 1.0) as indicated by the blue bar below the fan. Hold down 'F' and drag the pointer up down with the middle mouse button pressed to vary this value interactively.

How fast in seconds the strength can get from 0.0 to 1.0 for this tree model. Increase this number to slow down how quickly the tree responds to wind strength changes (the white tick on the blue bar indicates where the strength really is).

How fast in seconds the direction can change by 180 degrees. Increase this number to slow down how quickly the tree responds to wind direction changes.

Controls how quickly the primary wind motion (side to side oscillation) responds to wind strength changes. Increase this number to make primary wind motion take longer to take affect when the wind strength increases.

Primary motion is controlled by each vertices Z position relative to the trees height. Set the height of the tree here to roughly the height of your tree.

By default, the tree will oscillate more at the top than at the bottom in a linear fashion (when the exponent is 1.0). Increase this value to make the effect focused higher up the tree.

Under large oscillations the tree geometry will stretch. Increase this value to combat this by lowering the Z coordinate of each vertex based on how much it moved (the value is a percentage of how much it moved).

Controls how far the tree moves during each oscillation at low wind strengths.

Controls how far the tree moves during each oscillation at high wind strengths.

Controls how fast the tree oscillates at low wind strengths.

Controls how fast the tree oscillates at high wind strengths.

Controls how quickly the secondary wind motion (random direction oscillation) responds to wind strength changes. Increase this number to make secondary wind motion take longer to take affect when the wind strength increases.

Controls how far the tree moves during each oscillation at low wind strengths.

Controls how far the tree moves during each oscillation at high wind strengths.

Controls how fast the tree oscillates at low wind strengths.

Controls how fast the tree oscillates at high wind strengths.

Controls how quickly the leaf wind motion responds to wind strength changes. Increase this number to make leaf wind motion take longer to take affect when the wind strength increases.

Controls how much the lighting changes on leaves as they oscillate. Higher numbers result in a more dramatic effect.

Wind oscillation distances are multiplied by this amount for leaves on the side of the tree that the wind is blowing towards.

Controls how far the leaf vertices move during each oscillation at low wind strengths.

Controls how far the leaf vertices move during each oscillation at high wind strengths.

Controls how fast the leaves oscillate at low wind strengths.

Controls how fast the leaves oscillate at high wind strengths.

Controls how quickly the frond ripple motion responds to wind strength changes. Increase this number to make frond rippling take longer to take affect when the wind strength increases.

Controls how far the frond vertices move during each oscillation at low wind strengths.

Controls how far the frond vertices move during each oscillation at high wind strengths.

Controls how fast the frond vertices oscillate at low wind strengths.

Controls how fast the frond vertices oscillate at high wind strengths.

Sample tiling along the length of the frond.

Sample tiling across the frond.

Controls how often gusts occur. Higher numbers result in more gusting.

How much the entire tree leans in the direction of the wind based on the combined strength of the strength setting and how strong the gust is. Gust strength is indicated by the red bar under the fan.

Increase this number from 1.0 to make secondary oscillations go with the wind. Doing this results in branch stretching and must be used sparingly.

The minimum strength each new gust can be. This value is added to the nominal wind strength.

The maximum strength each new gust can be. This value is added to the nominal wind strength.

The shortest time period each new gust can last in seconds.

The longest time period each new gust can last in seconds.

Positive numbers cause branches and fronds to blow up in high wind, negative numbers make them blow down in high wind.

This parameter controls how much wind direction is adhered to in secondary oscillations. 0.0 means not at all and 1.0 means all branches point in the direction of the wind as much as they can and do not oscillate.

The X,Y, and Z components of the Rotation: Angle.

The amount of rotation around the rotation angle.
