Unity3D调用摄像头，画面为翻转的问题

Unity3D中新建一个工程，加一个Plane，新建一个C# 脚本，调用摄像头，不过显示的图片居然是翻转的，也就是头朝地下。调了半天，原来是Plane反掉了，Plane的Rotation X值改为90，Y改为180就可以了。

晒下代码：

using UnityEngine;
using System.Collections;

public class C : MonoBehaviour 
{
	WebCamTexture webcamTexture;
	// Use this for initialization
	void Start () 
	{
		WebCamDevice[] devices = WebCamTexture.devices;
		if (devices.Length > 0)
		{
			webcamTexture = new WebCamTexture(devices[0].name, 320, 240, 25);
			renderer.material.mainTexture = webcamTexture;
			webcamTexture.Play();
		}
	}
	
	// Update is called once per frame
	void Update () 
	{
	
	}
}

或者：

using UnityEngine;
using System.Collections;

public class B : MonoBehaviour 
{
	public string deviceName;  
	WebCamTexture tex;
	
	IEnumerator Start()
    {
        //获取授权  
        yield return Application.RequestUserAuthorization(UserAuthorization.WebCam);  
        if (Application.HasUserAuthorization(UserAuthorization.WebCam))  
        {  
            WebCamDevice[] devices = WebCamTexture.devices;  
            deviceName = devices[0].name;  
            tex = new WebCamTexture(deviceName, 480, 320, 25);  
            renderer.material.mainTexture = tex;  
            tex.Play();  
        }
    }
}
