# mipMapsPreserveCoverage

> Enables or disables coverage-preserving alpha mipmapping.

## Definition

* **Type:** Property
* **Namespace:** [UnityEditor](/engine/6000.0/script-reference/unityeditor.md)
* **Assembly:** UnityEditor

```csharp
public bool mipMapsPreserveCoverage { get; set; }
```

### Remarks

Enable this to rescale the alpha values of computed mipmaps so coverage is preserved. This means a higher percentage of pixels passes the alpha test and lower mipmap levels do not become more transparent. This is disabled by default (set to false).
