Define a Town (POI) (exemple with Montiniac on EDEN)

we can see the first 5 prefab are MCP_Montignac_"Directions"

Theses prefab need to place at all the entry of the city

After we see JWK_AmbientDonationPoint

This seem to be triggering some action when you bring supply on a vehicule to a city
They are placed all around a city in some logic point where the player have to realise that he can donate supplies here (place on the city, pharmacy, shopping mall to be more roleplay)
Jail zones are not required, if there is no extra one then the building will spawn default zone (which covers the building itself only).

You have to put also a jailzone in each city (seems to be auto generated with thje police building dont bother add zone)
After set the type of the city (City, town, Village) it is recommaend to let a jail only in town and city

To setup the size of the city:

JWK_TownController prefab -> JWK_TownEntity -> at the end of the properties list.
