* **Assembly:** UnityEngine.TerrainModule

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

### Parameters

**** (\[Terrain]\(/engine/7000.0/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.
