[code=csharp]using System.Collections;
using System.Collections.Generic;
using UnityEngine;
/// <summary>
/// made by u3dchina.com

public class FlipNormals : MonoBehaviour
{
// Use this for initialization
void Start()
{
      Mesh mesh = this.GetComponent<MeshFilter>().mesh;
      Vector3[] normals = mesh.normals;
      for (int i = 0, lenI = normals.Length; i < lenI; i++)
      {
         normals = -1 * normals;
      }

      mesh.normals = normals;
      Debug.Log("subMeshCount:"+mesh.subMeshCount);
      for (int i = 0, lenI = mesh.subMeshCount; i < lenI; i++)
      {
         int[] tris = mesh.GetTriangles(i);

         for (int j = 0, lenJ = tris.Length; j < lenJ; j+=3)
         {
            int temp = tris[j];
            tris[j] = tris[j + 1];
            tris[j + 1] = temp;
         }
         mesh.SetTriangles(tris, i);
      }
}

// Update is called once per frame
void Update()
{
}
}[/code]
创建一个character controller、plane、及一个sphere当天空盒，把该脚本拉到sphere就ok了。
