# TerrainPaintToolWithOverlaysBase

> The abstract class that TerrainPaintToolWithOverlays inherits from.

## Definition

* **Type:** Class
* **Namespace:** [UnityEditor.TerrainTools](/engine/6000.6/script-reference/unityeditor/terraintools.md)
* **Assembly:** UnityEditor
* **Inherits from:** [EditorTool](/engine/6000.6/script-reference/unityeditor/editortools/editortool.md)

```csharp
public abstract class TerrainPaintToolWithOverlaysBase : EditorTool
```

## Remarks

Contains fields that can be overridden when you implement your own terrain painting tools to display in Terrain overlays. When you create custom Terrain Tools, they must inherit from the [TerrainPaintToolWithOverlays\<T>](/engine/6000.6/script-reference/unityeditor/terraintools/terrainpainttoolwithoverlays1.md) class rather than this class.
