I am doing one of Unity's official tutorials: Survival Shooter.
Unity version: 5.3.4f1 Device: Macbook, OSX 10.11
http://unity3d.com/learn/tutorials/projects/survival-shooter/environment?playlist=17144
The problem: Baking process completes almost instantly and the floor is not highlighted by a blue mesh (where highlight should mean that navmesh is calculated for there).
Then, I checked the completed scene (which was already created by Unity Team), it showed the floor fully highlighted. I just hit the bake again without touching anything and the same problem happened. So, there must be something else as I tried the original scene file without changing anything.
What am I missing here? Is there a Unity editor setting or something like that which can break the baking process?
