Create Neighbor Terrains 

The Create Neighbor Terrains tool allows you to quickly create adjacent Terrain tiles, which automatically connect. In the Terrain Inspector, click the Create Neighbor Terrains icon.

When you select the tool, Unity highlights areas around the selected Terrain tile, indicating spaces where you can place a new, connected tile.

Enable the Fill Heightmap Using Neighbors checkbox to fill the new Terrain tile’s heightmap with a cross-blend of neighboring Terrain tiles’ heightmaps, which ensures that the height of the new tile’s edges match up with adjacent tiles.

Choose a property from the Fill Heightmap Address Mode drop-down menu to determine how to cross-blend the heightmaps of adjacent tiles:

プロパティー 説明
Clamp Unity performs a cross-blend between the heights along the edges of neighboring Terrain tiles that share a border with the new tile. Each Terrain tile has up to four neighboring tiles: top, bottom, left, and right. If there is no tile in any of the four adjacent spaces, the heights along that respective border are taken as zero.
Mirror Unity mirrors each of the adjacent Terrain tiles, and cross-blends their heightmaps to produce the heightmap for the new tile. If there is no tile in any of the four adjacent spaces, the heights for that specific tile location are taken as zero.

To create a new Terrain tile, click any of the available spaces next to an existing tile. The Editor creates a new Terrain tile in the same group as the selected Terrain, and copies over the settings of the tile it connects to. It also creates a new TerrainData Asset.

デフォルトでは、Terrain タイルの Terrain SettingsAuto connect は有効です。 Auto connect が有効な場合、Terrain システムは隣接する Terrain タイル間の接続を自動的に管理します。タイルは自動的に同じ Grouping ID を持つ任意の近隣タイルと接続します。

On rare occasions, you might lose connections between tiles if you change the Grouping ID, or disable Auto connect for one or more tiles. To recreate connections between Terrain tiles, click the Reconnect button. Reconnect only connects two adjacent tiles if they have the same Grouping ID and if both tiles have Auto Connect enabled.

Connecting Terrain tiles in a group allows you to use other tools to paint textures or adjust the heightmaps of the group so that there are no seams. At run time, the Terrain system automatically blends the tessellation and normal map of connected tiles. This ensures they appear as a single piece of Terrain, without seams or artifacts.

1 つのストロークで 2 つの未接続のタイルをペイントしようとすると、Unity はそれらを別々のタイルとして扱います。そのため、適用するエフェクトは 1 つのタイルにのみ表れたり、各タイルで異なる様相になる場合があります。
