# supportsBackbufferInMultipleRenderTargets

> Indicates whether the current graphics backend forbids mixing system backbuffers with custom render targets.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.7/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public static bool supportsBackbufferInMultipleRenderTargets { get; }
```

### Remarks

Some graphics APIs — most notably OpenGL — do not allow using system-provided backbuffers and user-provided render textures together as color or depth attachments within a single rendering operation. In these cases, rendering to the system backbuffer while also binding a custom texture for either color or depth may require an additional blit step or trigger undefined behavior.
