I'm looking for a 3D engine that would allow me to do open-world games. Basically: - the game is looks like one big "map" of several km wide where you can walk from one point to another - there would be a possibility to fly so I can't compute in advance how much of the terrain is visible (you can fly up and see a lot of things around you) - should handle a day/night cycle (so I can't really pre-compute a general lightning since it would change)
I don't really need something that would be very performant because I don't plan on havings lots and lots of models etc (I'm not doing a AAA game), I'm mainly looking for a solution that is scalable, ie not something where I just load all the game assets in memory for the whole world and then not display most of it.
Do you know any engines (possibly free and open source) who can currently handle this? I tried looking at how to do this with Ogre but I don't think it's really possible
