Duplicated Terrain Object and Data STILL affects other terrains

Okay this limitation has bothered me enough now, I finally decided to solve this once and for all. Here is the step-by-step solution!!

1. Select the Terrain prefab AND its corresponding Terrain-Data prefab in your Project folder.

2. Press Ctrl-D to duplicate BOTH of these objects. (Give them a special name.)

3. In your project folder, select your NEW Terrain prefab.
   IMPORTANT: In the inspector, click the "Gears" icon in the upper-right corner of Terrain (Script). Select: RESET!!! <-- this does the MAGIC ! :D Now, notice it says "Terrain Asset Missing, Assign" Drag your NEW Terrain-Data prefab (the icon looks like a tiny mountain) onto it.

4. Now do the same (drag/drop) the NEW Terrain-Data for your Terrain-Collider component.

5. Finally, drag your NEW Terrain prefab into your scene.

6. Congratulations! You have a unique terrain you can adjust, paint, edit without effecting the original!

You're Welcome!! ;)

1. Duplicate your Terrain asset (IN YOUR ASSETS FILES).

2. Duplicate your Terrain object (IN THE HIERARCHY).

3. Open the Debug window into the inspector of the duplicated terrain object. --- INTO DEBUG WINDOW ---

4. Terrain -> Terrain data = change to your duplicated terrain asset.

5. Terrain Collider -> Terrain data = change to your duplicated terrain asset.

Yep. Figured it out. I was trying to set the terrain data rather than actually replacing the terrain itself, as I assumed the data was where it stored everything. Was just a case of deleting the entire terrain that was already in the scene and dragging the correct version in.
