I'm making a game where a helicopter travels around.
I'd like that the environment around be as realistic as possible. For instance, since the helicopter can travel at speeds up to 200 km/h, I want the player to see very far away, in a realistic fashion.
I'm talking about a map where let's say there is a "real" mountain 50km away and you could "walk" there, as well as the mountain looking like a mountain in game from the any distance (no matter the quality).
How could I manage my map in UE4 that would allow me to implement such a "real" world?
