Mesh.uv4

Descripción

The fourth texture coordinate set of the mesh, if present.

	// Generate planar uv coordinates for all 4 uv sets

	function Start () {
		var mesh : Mesh = GetComponent.<MeshFilter>().mesh;
		var vertices : Vector3[]  = mesh.vertices;
		var uvs : Vector2[] = new Vector2[vertices.Length];

		for (var i = 0 ; i < uvs.Length; i++)
			uvs[i] = Vector2 (vertices[i].x, vertices[i].z);

		mesh.uv2 = uvs;
		mesh.uv3 = uvs;
		mesh.uv4 = uvs;
	}
