I'm hosting a server for a while that is a map where players can join and help by building more aspects in the map, it will be a big area with different locations, a valley town, long roads, airport, docks, city, a circuit, beach, and more possible areas.
Feel free to join if you want to contribute in the map, we're using Modter mainly, the server is hosted 24/7.
There is also a Discord group for it, feel free to join:
