# cullingMask

> This is used to render parts of the reflecion probe's surrounding selectively.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.3/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public int cullingMask { get; set; }
```

### Remarks

If the [GameObject](/engine/6000.3/script-reference/unityengine/gameobject.md)'s `layerMask` AND the probe's `cullingMask` is zero then the game object will be invisible from this probe. See [Layers](/engine/6000.3/manual/working-with-gameobjects/layers.md) for more information.

```csharp
using UnityEngine;
using UnityEditor;

public class ExampleScript : MonoBehaviour
{
    void Start()
    {
        var probe = GetComponent<ReflectionProbe>();
        // Only render objects in the first layer (Default layer) when capturing the probe's texture
        probe.cullingMask = 1 << 0;
    }
}
```
