Read time 1 minuteLast updated a month ago
Note
This tool is only available in the Terrain Tools package.
Use the Slope Flatten tool to flatten the details on top of a slope without changing the slope's average angle. For example, you can use it to:
  • Make a mountain top less jagged, without making the mountain less steep.
  • Smooth the transition from a plain to the mountain's side.
  • Make terraces, bridges, and other artificial features look unmaintained. Refer to Erode the terrain for other ways to do this.

Access the tool

To flatten the terrain, in the Terrain tile’s
Inspector

?

window, select the Paint Terrain tool > tool dropdown > Effects > Slope Flatten.
Tip

0.2
