# Height

> Sculpt the terrain's height with the built-in Terrain system and the Terrain Tools package

The Terrain's **Paint Terrain** tools sculpt the terrain to create mountains, valleys, and other topographical features. The primary height tools are available in both the built-in Terrain system and the Terrain Tools package. The advanced height tools and a selection of effect, transform, and erosion tools are available only in the [Terrain Tools package](https://docs.unity3d.com/Packages/com.unity.terrain-tools@latest/).

> **Note:**

> For information about the **Paint Texture** tool, refer to [Textures and layers](/engine/6000.3/manual/creating-environments/script-terrain/terrain-textures.md).
