Modify Terrain

Read more about terrain in this chapter.

In this section, we will modify the terrain to look like a grass field with a river:

Change material

Change all of the terrain to grass:

1. Click the terrain object in Viewport or select it in Outliner. In Tool Shelf, the tabs for the terrain object should be displayed:
   

2. In the Terrain Editor tab, open the Paint section and select the Paint brush:
   

3. Adjust the brush parameters:

   • Radius: 50
   • Strength: 1
   • Falloff: 0
   • Target Layer: grass

4. In Viewport, cover the terrain with paint by holding Left Button:
   

   Camera movement

   Hold the right mouse button and press W, A, S, D (forward, left, backward, right) and Q and E (lower or raise the camera) to move.

Change height

Make a deepening for a river:

1. Click the terrain object in Viewport. In Tool Shelf, the tabs for the terrain object should be displayed:
   

2. In the Terrain Editor tab, open the Sculp section and select the Sculp brush:
   

3. Adjust the brush parameters:

   • Radius: 20
   • Strength: -5
   • Falloff: 0.7

4. In Viewport, draw a river by holding Left Button:
   

   Black holes

   Some shadows may appear as if they are completely black. To fix this, just move closer to the shadow in Viewport.

Add water

Fill the river with water:

1. In Outliner, right-click the scene_art section and select Create:
   

2. Find the water_prefab_lakebig prefab and add it to the scene:
   

3. Select the water prefab in Outliner, then, in Viewport, move and scale the instance of the water_prefab_lakebig prefab so it fills the river:
   

   Object editing controls

   Press R once to switch to the Scale mode and drag the axes of the object. Press W to switch back to the Translate mode.

   Warning

   Do not rotate water prefabs around Y and Z axes, or the water physics will break.

4. In Inspector, in the prop_water property, change the color of the water surface:

   • Volume properties > Refraction filter:

     • Color: 255, 69, 99, 77
     • Density: 0.5

   • Volume properties > Fog:

     • Color: 255, 69, 99, 77
     • Density: 0.2

5. In the prop_water > waves property, change the amplitude of the waves:

   • Small waves amplitude: 0.5
   • Big waves amplitude: 2

Tip

If the water color doesn't change or it looks too dark, click Recalculate Lighting in the Viewport toolbar:
