Hello, I've created a local map of a city we are developing a Unity experience for. I'm able to move through the default 2D base layer map in Unity and all that. Is there a way to get 3D mesh data ala Google World 3D? Just as an example, we would want a controllable avatar to be able to walk through a 3D rendering of the city. Any pointers, tutorials, docs, references would be much appreciated.
