I have been modelling with blender for a year or so and I am starting to work on a pretty large project, something of such scope I have never attempted.
I have created a really rough mock up for a world map I want to create. I am having a hard time figuring out how I should tackle the final product. It is about 2km square with a slight incline and on one side is ocean. I want to eventually import it into unreal or unity.
Should I create a rough layout of the entire terrain and place the roads, buildings and trees on top and add details to the terrain where I need them? Another way I was thinking was to add the buildings, place the roads, parking lots etc in between and only add terrain where it is exposed?
Or is there a better way?
