Why are the terrains in my seperate scenes linked when edited?

Unity Engine
1

When I make a terrain and ‘save scene as’ Untitled1. Then While in Untitled1. I ‘save scene as’ Untitled2…

  • Now I have (scene) Untitled1.
  • and (scene) Untitled2.
  • When I edit the Terrain in Untitled2 why does it edit also the terrain in Untitled1?

Is this suppose to happen?

Also when I

  • make a prefab of a Terrain,

  • duplicate it,

  • change the name.

  • Make a prefab(of the newly named)

  • It still edits both terrains when I edit one.

Is this suppose to happen?

What I’m trying to do is create several copies of a similar map so that I can tweak it for certain scenario: how do I go about doing this (considering that normal procedures aren’t working)?

The Terrain data (hight-map , size and some other settings) is saved inside the Terrain asset and not inside the scene.
You will need to duplicate the Terrain asset In your Project view and use the duplicate for the second scene.
