public static function MultiTexCoord(unit: int, v: Vector3): void;
public static void MultiTexCoord(int unit, Vector3 v);

Description

Sets current texture coordinate (v.x,v.y,v.z) to the actual texture unit.

In OpenGL this matches glMultiTexCoord for the given texture unit if multi-texturing is available. On other graphics APIs the same functionality is emulated.

The Z component is used only when:
1. You access a cubemap (which you access with a vector coordinate, hence x,y & z).
2. You do "projective texturing", where the X & Y coordinates are divided by Z to get the final coordinate. This would be mostly useful for water reflections and similar things.

This function can only be called between GL.Begin and GL.End functions.

	// Changes between two textures assigned to a material
	// When pressed space
	var mat : Material;
	private var flagTex : boolean = true;
	function Update() {
		if (Input.GetKeyDown(KeyCode.Space)) {
			if(flagTex) {
				flagTex = false;
			} else {
				flagTex = true;
			}
		}
	}
