# importance

> Reflection probe importance.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.5/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

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

### Remarks

The bigger the value the more important the probe is. When deciding which probe to use for the object, Unity will always pick **Important** probe over the **Not Important**. This property also affects blending, if object is inside both **Important** and **Not Important** probe, only **Important** probe will be used, when object is leaving **Important** probe bounding box, it will gradually blend over **Not Important** probe. If both probes would have same importance, the object would use both probes.
