Grass Animation Node

This node simulates skewing and bending of grass chunks by offsetting vertex positions based on the input wind settings.

Usage Example

Name		Description
	Wind Animation Tiling	Controls frequency of the wind animation pattern.
	Wind Animation Speed	Determines how fast wind animation moves.
	Wind Animation Intensity	Determines how much an object is affected by the wind.
	Wind Direction	Controls the direction the wind is blowing across the surface. The first component affects the movement along the object's Y-axis, and the second component affects the movement along the object's X-axis.
	Normal Tangent Space	The vertex normal in tangent space, needed for accurate deformation. Vector (0,0,1) in tangent space provided by default.
	Object Height (In Meters)	The height of the object, used for correct vertical scale.
	Vertex Position Object Space	The position of the vertex in object space, used for calculating wind influence. The Vertex Position node with object space is provided by default.
	Position Offset Tangent Space	The calculated offset applied to vertex positions in tangent space for grass movement.
	Normal Tangent Space	Modified normal vector after animation process.
