首先，给镜头增加skybox，然后给镜头添加如下代码即可

 1     public class SkyboxCamera : MonoBehaviour {  
 2         public float rot = 0;  
 3         public Skybox sky;  
 4         // Use this for initialization  
 5         void Start () {  
 6             sky = GetComponent<Skybox>();  
 7         }  
 8           
 9         // Update is called once per frame  
10         void Update () {  
11             rot += 0.7f * Time.deltaTime;  
12             rot %= 360;  
13             sky.material.SetFloat("_Rotation", rot);  
14         }  
15     }
