How can I best implement a big map in a large, open world?

Hello! I have a few questions on the implementation of the big world.

Questions:

  1. Can I implement the same in the big world dayz?

  2. If you use the “Level Streaming” is the standard server Unreal engine will support?

  3. What are the options for the implementation of the big world?

  4. If correctly understood the player stands still and the map moves right?

  5. In this case, the multiplayer is going to be terrible in terms of performance, right?

  6. If that was right that the player stands still and the map moves that I need to rewrite the engine or something else to make this map was standing, and the player to move, right?

  7. If to make large map how to reduce the load, and then increased to 8 GB?
