```csharp
public bool GetMirrorViewBlitDesc(RenderTexture mirrorRt, out XRDisplaySubsystem.XRMirrorViewBlitDesc outDesc)
```

### Parameters

**** (\[RenderTexture]\(/engine/6000.0/script-reference/unityengine/rendertexture)): A render texture representing mirror view's render target.**** (\[XRMirrorViewBlitDesc]\(/engine/6000.0/script-reference/unityengine/xr/xrdisplaysubsystem/xrmirrorviewblitdesc)): Information that describes desired mirror view blit operation.

### Returns

| Type                                                          | Description                                                            |

Get a mirror view blit operation descriptor from the current display subsystem.

```csharp
public bool GetMirrorViewBlitDesc(RenderTexture mirrorRt, out XRDisplaySubsystem.XRMirrorViewBlitDesc outDesc, int mode)
```

### Parameters

**** (\[RenderTexture]\(/engine/6000.0/script-reference/unityengine/rendertexture)): A render texture representing mirror view's render target.**** (\[XRMirrorViewBlitDesc]\(/engine/6000.0/script-reference/unityengine/xr/xrdisplaysubsystem/xrmirrorviewblitdesc)): Information that describes desired mirror view blit operation.**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): The [XRMirrorViewBlitMode](/engine/6000.0/script-reference/unityengine/xr/xrmirrorviewblitmode.md) XR display should perform.
