Brushes

When you apply a tool such as Paint Texture or Smooth Height to the TerrainThe landscape in your scene. A Terrain GameObject adds a large flat plane to your scene and you can use the Terrain’s Inspector window to create a detailed landscape. More info
See in Glossary, Unity uses a Brush, which is a ScriptableObject in the Terrain system. The Brush defines the tool’s shape and strength of influence.

Built-in Brushes

Unity comes with a collection of built-in Brushes. They range from simple circles for quickly sketching designs, to more randomized scatter shapes that are good for creating detail and natural-looking features.

You can also select Brush Masks from the Terrain overlays. To see available Brush Masks from the Terrain overlays, select a Terrain tool that you can use to paint.

Custom Brushes

You can create your own custom Brushes with unique shapes or specific parameters for your needs. For example, use the heightmapA greyscale Texture that stores height data for an object. Each pixel stores the height difference perpendicular to the face that pixel represents.
See in Glossary Texture of a specific geological feature to define a Brush, then use the Stamp Terrain tool to place that feature on your Terrain.

To create a new Brush, click the New Brush button in the Terrain InspectorA Unity window that displays information about the currently selected GameObject, asset or project settings, allowing you to inspect and edit the values. More info
See in Glossary window.

After you click New Brush, the Select Texture2D window appears. Choose a Texture to define the shape of your new Brush, then use the Brush Inspector to adjust the Falloff and Radius Scale values.

Alternatively, right-click in the ProjectIn Unity, you use a project to design and develop a game. A project stores all of the files that are related to a game, such as the asset and Scene files. More info
See in Glossary window, and choose Create > Brush to create a new Brush. The default Brush shows a simple circle defined by a white Mask Texture, a Falloff curve, and a Radius Scale of 1. Use the Brush Inspector to change these values, or set a Texture to define the shape of the Brush. You can also use the Remap slider and the Invert Remap Range option to further modify the grayscale values of the Brush Texture.
