Using Terrain Tools

The Terrain Editor is used to create realistic landscapes like mountains, rivers, and canyons. To practice your skills in sculpting terrain, you’ll create a version of Old Faithful, a famous geyser that’s part of Yellowstone National Park in the United States.

  3. Change the brush size to be large. Then, left-click and drag the tool across the center of the terrain to create a rock formation.

Adding Water

With the rocks and salt, you’ll now add water to the geyser center.

  1. Under the Terrain Editor, click the Subtract button. This tool slowly removes terrain and is useful for creating caves, rivers, and lakes.

  2. Because all terrain is created on a grid, it’s important to get the right angle with your camera view. To make it easier to subtract, angle your camera so it points down at the geyser like below.

  3. Click and drag the tool over the center of the salt to create a hole in the center where you’ll add water.

Painting with Water

Instead of adding water, it’s best to paint with water. This makes sure that your water looks over terrain you’ve created.


  1. Paint the terrain in the middle to create water.
