# overrideIgnore

> Set this to true in order to enable the NavMeshBuildMarkup.ignoreFromBuild property.

## Definition

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

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

### Remarks

In the case when a `NavMeshBuildMarkup` is used to change only the area type of an object, `overrideIgnore` should be set to `false` so that the `ignoreFromBuild` property will not have any effect.

If none of the objects in a hierarchy are marked with `ignoreFromBuild` set to `true` then no objects in that hierarchy will be ignored while building the NavMesh.
