Missing shadows in fresh project

[David Williams]

When importing Cubiquity into a fresh project it initially appears that the shadows are not working. This is because the default shadow distance is set too low for something as large as a terrain. It doesn't work in the examples either, because these settings are per-game and not per-scene.

We should modify the Cubiquity examples to set the distance per-scene using the QualitySettings class (http://docs.unity3d.com/ScriptReference/QualitySettings.html). This way at least our examples will immediately work as expected.
