Welcome to part 13 of our Developer Tools Guide. This time, we will learn to use tools for editing terrain. To edit the terrain, we first need to add it to our map. To do so, open the Edit Terrain window, accessible from the Window menu. The red dot with an arrow shows our current position and the direction we’re looking at. We will then see a grid of our map, divided into blocks, where we can add terrain. Let’s add a few terrain blocks in front of us by holding down the left mouse button and selecting them.

Once they are selected, right click and select Create Block. Now, to edit the terrain blocks we need to go back to the Edit Terrain window. Ok, so as you can see we have quite a few different tools available to us here The first one, Raise/Lower Terrain does just that. You can raise and lower the terrain by moving the mouse up and down while holding the left mouse button. We can change the editing brush to suit our needs by changing its type, area and the precision of the effect. Those same options are available for most of the remaining tools. The second tool, lets us raise/lower the terrain by the value we input in the Height field. We use this tool by holding the left mouse button and dragging the cursor across the terrain. If we want to apply our Height value to the terrain again, release the left mouse button and start the process again. To lower the terrain using this tool, hold down CTRL during the process. The third editing tool is Pick/Set Height, allowing us to level the terrain to the selected height.

The value in the Height field is what you will level the terrain to. You can use the existing terrain’s value by holding down CTRL and clicking a spot on the terrain. That spot’s value will be automatically input into the ‘Height’ field. The Smooth tool is used to, well, smooth the terrain. It allows us to eliminate any rough edges or overly steep slopes. Another tool, Ramp, allows us to create terrain-based ramps between two set points. Essentially it enables us to create accessible paths to higher portions of the map. First, input the desired width of the ramp into Width field. To create the ramp, click and hold the left mouse button at the desired start of the ramp drag it over the final point, and then release the button. Second last tool is Material Painting, which allows us to paint our Terrain. By default, we already have a few brush tools allowing us to change the terrain’s texture from grass to mud, asphalt or sand. To add new, custom layer, we click Add Layer, then select Rename from the context menu, create a new name, and then double-click on it to edit it.

Every layer consists of 2 materials. You can define the look of the top and side layers. This is especially useful when creating realistic-looking slopes. The last tool, Remove Vertices, allows us to cut holes in the terrain. After the editing is finished, we can save and lock the terrain, which you can do in the block editing window, by selecting the blocks and choosing Lock Block from the context menu. Let’s test the terrain in-game. Now, every time we want to edit already existing blocks, we need to first unlock them by using Unlock Block.

To provide an example, let’s level our terrain. And that’s it for today’s tutorial. Thanks for watching..
