# Paint Terrain

**Paint Terrain** tools let you use a Brush to sculpt or paint the Terrain and make modifications. The Terrain Tools package adds 13 additional tools to the [6 built-in tools](https://docs.unity3d.com/Manual/terrain-Tools.html), and improves the functionality of the built-in [Paint Texture](https://docs.unity3d.com/Manual/terrain-PaintTexture.html), [Smooth Height](https://docs.unity3d.com/Manual/terrain-SmoothHeight.html), and [Stamp Terrain](https://docs.unity3d.com/Manual/terrain-StampTerrain.html) tools.

In the **Terrain Inspector**, click the **Paint Terrain** icon to display the list of Terrain tools.

The Terrain Tools package provides the following 13 additional tools, and improved **Paint Texture**, **Smooth Height**, and **Stamp Terrain** functionality.

* [__Bridge__](sculpt-bridge.md) creates a Brush stroke between two selected points to build a land bridge.
* [__Clone__](sculpt-clone.md) duplicates Terrain from one region to another.
* [__Noise__](sculpt-noise.md) uses different noise types and fractal types to modify Terrain height.
* [__Terrace__](sculpt-terrace.md) transforms Terrain into a series of flat areas like steps.
* [__Contrast__](effects-contrast.md) expands or shrinks the overall range of the Terrain height.
* [__Sharpen Peaks__](effects-sharpen-peaks.md) sharpens peaks and flattens flat areas of the Terrain.
* [__Slope Flatten__](effects-slope-flatten.md) flattens the Terrain while maintaining the average slope.
* [__Hydraulic__](erosion-hydraulic.md) simulates the effect of water flowing over the Terrain and the transport of sediment.
* [__Thermal__](erosion-thermal.md) simulates the effect of sediment settling on the Terrain while maintaining a natural slope.
* [__Wind__](erosion-wind.md) simulates the effect of wind transporting and redistributing sediment.
* [__Paint Texture__](paint-texture.md) is similar to the built-in Paint Texture tool, but with added functionality such as an improved workflow and a Terrain Layer Eyedropper tool.
* [__Pinch__](transform-pinch.md) pulls the height towards or bulges it away from the center of the Brush.
* [__Smudge__](transform-smudge.md) moves Terrain features along the path of the Brush stroke.
* [__Twist__](transform-twist.md) rotates Terrain features around the center of the Brush, along the path of the Brush stroke.
* [__Smooth Height__](smooth-height.md) is similar to the built-in Smooth Height tool, but includes two new parameters, **Verticality** and **Blur Radius**, which provide finer control when smoothing your Terrain.
* [__Stamp Terrain__](stamp-terrain.md) is similar to the built-in Stamp Terrain tool, but with added functionality such as **Min** and **Max** operations that provide finer control over Terrain. It now also includes the Mesh Stamp tool, which projects the shape of a mesh into the Terrain's heightmap.

You can also create your own custom Terrain painting tools. For more information, see [TerrainAPI.TerrainPaintTool](https://docs.unity3d.com/ScriptReference/Experimental.TerrainAPI.TerrainPaintTool_1.html) and [Create a custom Terrain tool](create-custom-tools.md).
