Question Locking Terrain?

Does anyone know of a way to lock unity terrain from edits?

In the attached image, I want to make edits to terrain #1 but NOT terrain #2. I do not want stokes or stamps to affect terrain #2.

Thx in advance!!

 

Seems like I stumped the Unity community on this one... Any takers?

 

Terrains have a group id that allows to edit multiple terrains at once. If you change the id of one, the terrains will be disconnected, so you will have to edit them separately.

 

Thanks for the reply r310!
As you can see with the images below the group IDs are different on Terrain_1 and Terrain_2 and yet they are still affected as if they were connected. Is there somewhere else I should be looking to change the group ID?

 

Does using overlays help???

 

You havent do anything, the terrain heights are the same as in the first post.
If you now try to edit them, you cant edit both at once, but the changes you made previously still there.

 

Was this ever resolved? I have 2 adjacent terrains similar to the screenshots above. I would like to lock one of the terrains from edits. If I attempt to edit an adjacent terrain, the locked terrain next to it will still be editable. Even though it's locked, it doesn't prevent the terrain from edits. The user can lock a terrain, select another terrain for edits, move the cursor over the locked terrain and still be able to edit that terrain.

 

I have tried many tricks (put it in prefabs or an other scene), but finally it turns out only one but simple solution works:
Turn off the Terrain Collider component!
