TABLE 7.1 Terrain editor tools

Tool icon
Use
1
Raise and lower the terrain. The selected
brush shape is used to emboss the
terrain. Each stroke in the same place
lifts the terrain.
2
Set the terrain height. This allows for the
exact altitude of any part of the terrain to
be set. A height of 0 is the same level as
the default terrain plane.
3
Smooth the terrain. This brush allows
you to smooth terrain heights between
differing levels to get a smoother effect
from jagged surfaces.
4
Add a texture to the terrain. This brush
allows you to paint the terrain with the
texture of your choice.
5
Place trees. Places trees on the surface
of the terrain under the brush location.
6
Place flowers, small plants, and rocks. This
brush performs the same action as the
tree planting brush; however, it places
smaller multiple models on the surface
of the terrain
7
Controls the overall settings for the terrain.
In this area you can set distances for level
of detail and when trees are rendered
as billboards instead of 3D objects.
These settings are for optimizing the
performance of the terrain in the game.
Step 5. For sculpting, select Tool 1. The brush size will affect the
area of ground you can sculpt in one stroke and the opacity of the
strength. A higher opacity will cause more of the terrain to be lifted
in one stroke.
Step 6. Hold down the left mouse button over the terrain to start
lifting the surface. At this stage begin with a basic outline of the Lake
Louise area based on Figure 7.5 , as shown in Figure 7.7 . To lower the
terrain, hold down the shift key with the mouse stroke.
Note
You might find it easier to replicate a real-world image if you place
it on a plane inside the Editor to use as a reference, as shown
in Figure 7.6 .
