Do you know how could replace the walls? Note that I did this terrain from some older (rather medieval) terrain. What carriages do you have in mind? Because there are hardly any models, once I had in mind some carriage system, but I still have no idea how to execute it. Other than that I'd probably need to make waypoints as regular wander would look odd on them. I had in mind Dunwall from Dishonored, but outcome is more a real life city, scaled down though for gameplay purposes.
