Modifying your Landscape with Sculpt tools
One of the main characteristics of a Landscape is that we can modify its shape directly inside the Engine to create diverse environments.
Sculpting tools are interactive tools. That means that you can use them directly on your Landscape inside the Level Viewport and see the result of your work in real time.
This is possible because when you use sculpting tools, you are painting a grayscale texture that the Engine uses to modify the Landscape. This texture is called a heightmap and works in the same way we learned about for a Roughness texture or a Metalness texture. White is equal to 1 and black is equal to 0 (zero). So, all the white pixels inside the heightmap will raise the Landscape shape. We will talk about it in the Unlocking heightmaps’ power section of this chapter.
To sculpt and modify our Landscape, we can use all the tools inside the Landscape mode’s Sculpt panel.
