After you've made a Prefab like this, you can easily add similar corner sections anywhere in the
level—just as easily as adding single mesh pieces. Simply drag and drop the Prefab asset into the
scene to create new instances (see Figure 2-22 ).

Don't stop here, however! Use this technique to identify all other relevant architectural configurations
that could be abstracted into reusable Prefab objects. The earlier you do this in your workflow,
the easier your level-building experience will be in the long term. However, exercise caution when
reusing only a few Prefabs, because it's easy for the repetition to become noticeable to the gamer,
making your environments feel dull and lifeless. See Figure 2-23 for a list of the Prefabs I've made for
CMOD.
