Step 7. Using a combination of Tools 1, 2, and 3, sculpt and smooth
the terrain into an approximate representation of the Lake Louise
landscape as shown in Figure 7.8 .

to represent Lake Louise.
Step 8. Once the basic terrain is constructed it can be textured. For
texturing, seamless images are required. These images must be placed
in the Project. Acquire these textures by searching online. An excellent
seamless texture pack is available at http://aeonicdesign.ca/Textures/
Step 9. Click on Tool 4 to select the terrain painting brush. Before
you can start coloring the terrain, the images need to be loaded as
terrain textures. Select the Edit Textures button as shown in Figure 7.9
and select Add Texture. A pop-up window will allow you to select the
image and its tile size. The larger the tile size, the more terrain a single
copy of the image will cover.
Step 10. Select a texture to be the first and click on Apply to add it
to the terrain texture list. Because the first texture added will cover
the entire terrain automatically, picking an image that represents the
most common surface color saves a lot of texturing work later.
Step 11. Add more images to the texture list and use the brush
size, opacity, and target strength settings to paint the terrain. The
opacity value sets how much of the underneath texture mixes with
the newly added texture, and the target strength is how much of the
added texture is placed on the surface. A low opacity will allow a lot
of the underneath color to show through. A low target strength will
add very little of the current texture to the surface. Experiment with
these values to get the effect right. If you make a mistake it is simple
enough to recolor over the mistakes.
