Calculates custom center-outwards tree wind sway with an adjustable multiplier.

TreeWindSwayCentral_AssetEditor.cs

// Tree Wind Sway Recalculator (Central)
// Recalculates vertex colors based on the proximity to center.
// Allows limiting sway with an adjustable multiplier.

var sway = 0.2f; 	// Sway multiplier 0.0 (none) to 1.0 (max)

var bias = 1.6f; 	// "Contrast" between center and outer parts, 
					// increasing this will make the middle more static,
					// and the outside move more.
				

var asset = ToolsModifierControl.toolController.m_editPrefabInfo as TreeInfo;
Vector3[] vertices = asset.m_mesh.vertices; Color[] colors = new Color[vertices.Length];
for (int i = 0; i < vertices.Length; i++) 
	colors[i] = new Color(0f, 0f, 0f, Mathf.Clamp((Mathf.Pow(Mathf.Sqrt(vertices[i].x * vertices[i].x + vertices[i].z * vertices[i].z), bias) / Mathf.Pow(bias, bias) * (sway/Mathf.Pow(bias, bias))), 0.0f, 1.0f));
