Thanks. But with your specs I do not think I could run this on my system. And you have 40fps with only 1 mesh? And without anything else (no folliage, buildings, etc.). I do not think this is an option for me, maybe not even for the player.
What would you recommend? Should I just use landscape actors with world partition?
edit: if I reduce the resolution to 1pixel = 3pixels, I can get my landscape in a 6k x 8k pixel map, and therefore I wouldn’t even need world composition, right? I would have to scale my map 3x and that would be it? (this would correspond to 11 zooms in terresculptor DEM explorer)
Another option, is to create different levels and make the player travel between them. One level per relevant city and its surroundings, although then it wouldn’t be a “continuous” open world. Nevertheless I could cover many more locations.
