I am making my own project using aircrafts. My project requires huge size of levels, between 20×20km and 50×50km(each end of the map will be 1M~2.5M units far from origin[0,0]). I tried to use the open world template but it was too laggy, while the basic template didn’t have any lag. I assume it was because my actor was too fast(30~200m/s) that each partition of the landscape was being loaded frequently.
Will there be any problem if I make a huge map using basic template rather than using open world template? My project won’t have cities or complicated buildings with a bunch of interiors inside. Just mountains with some trees or foliages using nanite, or only a vast sea.
