Terrain & Road Networks - What should come first, and what is the best of way of doing so?

Hello developers! :wave:

I’ve made multiple posts in regards of an experience I am making, and this is one of those. I am making a roleplay experience, and right now I am focusing on terrain and map design.

I have a basic idea of what I want the map to be, but I have zero clue how to achieve that.

  • How do I terrain my map? How should I scale it?
  • Should I scale it based on the road networks, or add them once the terrain is over.
  • Should I consider limiting the size of my map, or how big I go for?

Right now my main concern is how to combine my road networks with roblox terrain. Whether I should add them after the terrain is done, or before.

Also a way to imagine or preview what I’d like to have in studio would be great, but I don’t know how to do so.

Any help very appreciated!
