AddMatrix(name: string, value: Matrix4x4): void;
AddMatrix(nameID: int, value: Matrix4x4): void;

Description

Add a matrix material property.

Function variant that takes nameID is faster. If you are adding properties with the same name repeatedly, use Shader.PropertyToID to get unique identifier for the name, and pass the identifier to AddMatrix.

	var texture : Texture;
	var aMesh : Mesh;

// Create a new material with a shader // that rotates the texture.
