Create Neighbor Terrains

Creating and editing Terrains

To add a Terrain GameObject to your Scene, select GameObject > 3D Object > Terrain from the menu. This also adds a corresponding Terrain Asset to the Project view. When you do this, the landscape is initially a large, flat plane. The Terrain’s Inspector window provides a number of tools to create detailed landscape features.

provides five options to adjust your Terrain:

  • Create adjacent Terrain tiles.
  • Sculpt and paint your Terrain.
  • Add trees.
  • Add details such as grass, flowers, and rocks.
  • Change general settings for the selected Terrain.

For more information about each of these icons, see Create Neighbor Terrains, Terrain tools, TreesA GameObject and associated Component that allows you to add tree assets to your Scene. You can add branch levels and leaves to trees in the Tree Inspector window. More info

, Grass and other details, and Terrain Settings.

Select the paintbrush icon to access painting tools, which allow you to modify the Terrain. Use the cursor to sculpt the height of the Terrain, or paint texture onto the Terrain. Choose from several built-in Brush shapes, or define your own Brush using a texture. You can also change the size and opacity (the strength of the applied effect) of the Brush. Once you’ve defined the properties, your cursor takes the shape of the selected Brush. Click or drag on the Terrain to create different shapes and textures.

Similar to how you paint with a Brush on the Terrain, you can add textures, trees, and details like grass, flowers, and rocks. You can also create additional connected Terrain tiles, change the height of an entire tile, and even write custom Brushes with complex effects.

Additionally, the standard F keystroke works slightly differently for Terrain. As Terrains are typically very large, when you press the F key, the SceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info

view focuses on the area where you position the cursor. This provides a very quick and intuitive way to jump to the Terrain area you want to edit. If you press F while the cursor is not over a Terrain tile, it uses the standard framing behavior, framing the selection around the whole GameObjectThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. A GameObject’s functionality is defined by the Components attached to it. More info
