## Definition

* **Type:** Field
* **Namespace:** [UnityEngine.Rendering](/engine/6000.0/script-reference/unityengine/rendering.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
EnableSphereCulling = 1
```

### Remarks

The sphere is defined by [RayTracingInstanceCullingConfig.sphereCenter](/engine/6000.0/script-reference/unityengine/rendering/raytracinginstancecullingconfig/spherecenter.md) and [RayTracingInstanceCullingConfig.sphereRadius](/engine/6000.0/script-reference/unityengine/rendering/raytracinginstancecullingconfig/sphereradius.md) values.

A Renderer in the Scene is accepted to the acceleration structure if its AABB lies completely or partially inside the sphere.
