I want to create a terrain/world map for my 3d game.
I want a huge map. For example, ill make it in Blender or generate from a heightmap. Then I plan to divide it in chunks so I can load/unload and show/hide them when needed in the game.
If I want to remake the map, then I will have to divide it in chunks again, and again spend time on placing world objects on the terrain. I'm not sure that is the best way.
What approach is optimal here?
