# CullingOptions

> Flags used by ScriptableCullingParameters.cullingOptions to configure a culling operation.

## Definition

* **Type:** Enum
* **Namespace:** [UnityEngine.Rendering](/engine/6000.6/script-reference/unityengine/rendering.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
[Flags]
public enum CullingOptions
```

## Remarks

Unity sets some of the [CullingOptions](/engine/6000.6/script-reference/unityengine/rendering/cullingoptions.md) flags with default values, and others depending on the properties of the [Camera](/engine/6000.6/script-reference/unityengine/camera.md) from which you obtained the [ScriptableCullingParameters](/engine/6000.6/script-reference/unityengine/rendering/scriptablecullingparameters.md) struct. You can override these values before performing the culling operation.
