Question

我的相机有问题，我想拍一张截图，但是我收到了这个错误：

Flare渲染器更新未找到UnityEngine.Camera:Render（） c__Iterator4：MoveNext（）（at 资产/脚本/ ActionCam.cs：43）

我的代码：

public IEnumerator TakeScreenshot() {
        yield return new WaitForEndOfFrame();

        Camera camOV = _Camera;

        RenderTexture currentRT = RenderTexture.active;

        RenderTexture.active = camOV.targetTexture;
        camOV.Render(); // here is the problem...
        Texture2D imageOverview = new Texture2D(camOV.targetTexture.width, camOV.targetTexture.height, TextureFormat.RGB24, false);
        imageOverview.ReadPixels(new Rect(0, 0, camOV.targetTexture.width, camOV.targetTexture.height), 0, 0);
        imageOverview.Apply();

        RenderTexture.active = currentRT;

        byte[] bytes = imageOverview.EncodeToPNG();
        string path = ScreenShotName(Convert.ToInt32(imageOverview.width), Convert.ToInt32(imageOverview.height));

        System.IO.File.WriteAllBytes(path, bytes);
    }

有我的相机设置：

如果我停用“Flare Layer”，我不会收到此错误，但我的屏幕截图或多或少是空的，只有天空盒：

任何想法？

我统一使用3种类型的屏幕截图：

Application.CaptureScreenshot（ScreenSgotFile）：不再使用，因为我更喜欢将屏幕截图存储在内存中的方法。（我不需要该文件，因为它附加到MailMessage并由SmtpClient发送）
OnPostRender（必须连接到相机）：

    void OnPostRender(){  
        Texture2D ScreenShot=new Texture2D(Screen.width, Screen.height, TextureFormat.RGB24, false);  
        RenderTexture.active=null;  
        ScreenShot.ReadPixels(new Rect(0, 0, Screen.width, Screen.height), 0, 0);  
        ScreenShot.Apply();  
        byte[] PngData=ScreenShot.EncodeToPNG();  
        PngStream = new MemoryStream(PngData);  
        //File.WriteAllBytes(FileShot, PngData);  

        // Preview on a sprite  
        Sprite Spr=Sprite.Create(ScreenShot, new Rect(0, 0, ScreenShot.width, ScreenShot.height),Vector2.zero, 100);  
        Preview.sprite=Spr;  
        Preview.gameObject.SetActive(true);  
    }

相同的代码，但在框架的末尾：

    void Update(){  
        ...  
        StartCoroutine(ScreenShotAtEndOfFrame());  
    }  

    public IEnumerator ScreenShotAtEndOfFrame(){  
        yield return new WaitForEndOfFrame();  

        Texture2D ScreenShot=new Texture2D(Screen.width, Screen.height, TextureFormat.RGB24, false);  
        RenderTexture.active=null;  `enter code here`
        ScreenShot.ReadPixels(new Rect(0, 0, Screen.width, Screen.height), 0, 0);  
        ScreenShot.Apply();  
        byte[] PngData=ScreenShot.EncodeToPNG();  
        PngStream = new MemoryStream(PngData);  
        //File.WriteAllBytes(FileShot, PngData);  

        // Preview on a sprite  
        Sprite Spr=Sprite.Create(ScreenShot, new Rect(0, 0, ScreenShot.width, ScreenShot.height),Vector2.zero, 100);  
        Preview.sprite=Spr;  
        Preview.gameObject.SetActive(true);  
    }
