Tips and Tricks
Note that the screenshot in
Figure 6.10
shows the already resized terrain;
however, Unity draws the newly sized terrain only after the Set Resolution
button is pressed.
Why?
Why not just use the Scale tool? It doesn't work on terrains. Probably
because of the parametric and procedural basis of terrains, the Scale and
Rotate tools won't affect them. The Move tool will, but the only way to
change the size of a terrain is via the Set Resolution drop-down menu.
Why?
Why so small? Remember that with the fog the player won't be able to see
much beyond a few feet off the end of the dock. If a sunny bright scene was
called for in the game, a big terrain could be great to show the other side of
a river or bay and the land that emerges there, but in this case we are only
building small chunks of stuff right around the existing geometry of the
EntryWay. Keeping the terrain a reasonable size keeps all the relevant assets
in a size and placement that makes moving around the scene easier.
A size of 150×150 is just an approximation of the size of the scene, and
was found through trial and error. The height setting of 35 indicates the
highest the mountains will rise off the surface of the terrain. This too
can and might be edited later, but a reasonable height setting allows for
easier fine-tuning as the terrain is painted.
Step 4:
Move the terrain so that it sits beneath the water and extends
beyond the edges of the dock, and also that the EntryWay is situated
roughly in the middle of the terrain (
Figure 6.11
).
