New to these forums and to Unreal engine in general. As you can tell by the title, I’m insane, and far too ambitious for my own good, Lol. I have a project in mind to build out my homebrew fantasy world on a 1:1 scale in UE4. This is not intended for multiplayer or for any actual singleplayer game really. I just want to walk around my creation. While I’m building the continent in world machine I’ve been trying to research if it’s feasible to get the whole thing in there at once or if I’ll have to settle for cutting it up into a lot of different project files. I’ve seen that it’s “theoretically” possible to build as large a map as I want using world composition, origin shifting, etc. I haven’t seen an answer though on whether this is actually realistically possible given that I don’t have a ten thousand dollar super computer.
So I’m asking if my ambitions need to be reeled in here (I’m guessing they probably do). I imagine even with world comp and other things to help lighten the load it still must be taxing to load even a 1/10th of what I’m going for. So what are some examples of some of the largest maps made and how taxing is it on the hardware? Even if it is possible, can the maps be populated with plants and buildings, etc. with nice shaders and stuff at this size? Or does a map this size need to essentially be empty to even load?
What I’d like to do to start with is a map roughly 10x10 km and maybe build out from there. So my other question is, can I swap out maps in the same UE4 project as I detail more areas of my game world in world machine? Say I import the map from world machine begin to populate it with buildings and decide later to change rivers or mountains or detail surrounding areas, can I pop that new map (or adjoining maps using world comp. and grow the map as I go) in place of the old one and keep all the things?
