Mesh.uv2 第二UV贴图

var uv2 : Vector2[]

Description描述

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

如果存在,这是为网格设定的第二个纹理坐标。

using UnityEngine;
using System.Collections;

	public class example : MonoBehaviour {
	void Start() {
		Mesh mesh = GetComponent<MeshFilter>().mesh;
		Vector3[] vertices = mesh.vertices;
		Vector2[] uvs = new Vector2[vertices.Length];
		int i = 0;
		while (i < uvs.Length) {
			uvs[i] = new Vector2(vertices[i].x, vertices[i].z);
			i++;
		}
		mesh.uv2 = uvs;
	}
}
// Generate planar uv coordinates for the secondary uv set
// 通过第二个uv的设定形成平面纹理坐标
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;
}
