> Creates a TerrainMap from the neighbors connected to the origin Terrain.

## Definition

* **Type:** Method
* **Namespace:** [UnityEngine.TerrainUtils](/engine/6000.5/script-reference/unityengine/terrainutils.md)
* **Assembly:** UnityEngine.TerrainModule

```csharp
public static TerrainMap CreateFromConnectedNeighbors(Terrain originTerrain, Predicate<Terrain> filter = null, bool fullValidation = true)
```

### Parameters

**** (\[Terrain]\(/engine/6000.5/script-reference/unityengine/terrain)): Terrain that is given tile coordinate (0,0).**** (\[Predicate\<Terrain>]\(https\://learn.microsoft.com/dotnet/api/system.predicate)): Filter to apply when populating the map. If null, no filter is applied.**** (\[bool]\(https\://learn.microsoft.com/dotnet/api/system.boolean)): Validate the Terrain map. Default is true.

### Returns

| Type                                                                                 | Description                                                                         |
| ------------------------------------------------------------------------------------ | ----------------------------------------------------------------------------------- |
| [TerrainMap](/engine/6000.5/script-reference/unityengine/terrainutils/terrainmap.md) | The resulting Terrain map. Can return null when no Terrain objects pass the filter. |

### Remarks

Creates a [TerrainMap](/engine/6000.5/script-reference/unityengine/terrainutils/terrainmap.md) of all the Terrain neighbors connected to the origin Terrain that pass the filter validation.
