Terrain Edit

The Terrain Edit section contains three tools — Duplicate, Clean Remove, and Split.

Duplicate

The Duplicate tool copies selected Terrain in the Scene or Hierarchy, and also copies the associated Terrain data asset files. By doing so, the duplicated Terrain does not share the same Terrain data assets with the source Terrain, which allows you to edit the duplicates without modifying the original Terrain.

To start the copy process, select your source Terrain in the Scene or Hierarchy, and click the Duplicate button. You cannot undo this process.

Clean Remove

Clean Remove lets you delete selected Terrain in the Scene or Hierarchy, and also delete the corresponding Terrain data asset files.

To start the clean remove process, select your target Terrain in the Scene or Hierarchy, and click the Remove button. You cannot undo this process.

Split

The Split tool lets you divide Terrain into smaller tiles while properly preserving Terrain height, Terrain Layers, and other details.

Property	Description
Tile Split	The number of tiles along the X and Z axes after the split.
Auto Update Terrain Settings	Enable the checkbox to copy settings from the original Terrain. Disable the checkbox to use default Terrain settings on the new tiles.
Keep Original Terrain	Enable the checkbox to keep a copy of the original Terrain even after the split. Disable the checkbox to remove the original Terrain after the split.

After you configure these settings, click the Split button to divide the selected Terrain in the Scene or Hierarchy.
