terrain-set-neighbors	Set the neighboring `Terrain`s of a center `Terrain` (left / top / right / bottom) so Unity blends seams and LOD across tiles. Omitted neighbors are treated as null.	generated-by mcp-plugin-dotnet

Terrain / Set Neighbors

Wire up the neighbor terrains of a center Terrain via Terrain.SetNeighbors.

Inputs

• gameObjectRef — the center Terrain GameObject (required).
• leftRef / topRef / rightRef / bottomRef — optional GameObjects hosting the neighboring Terrains. Any omitted side is set to null.

Behavior

Resolves each provided neighbor GameObject to its Terrain component, calls center.SetNeighbors(left, top, right, bottom), and triggers Terrain.Flush(). Marks the scene dirty and repaints. Runs on the Unity main thread.

How to Call

unity-mcp-cli run-tool terrain-set-neighbors --input '{
  "gameObjectRef": "string_value",
  "leftRef": "string_value",
  "topRef": "string_value",
  "rightRef": "string_value",
  "bottomRef": "string_value"
}'

For complex input (multi-line strings, code), save the JSON to a file and use:

unity-mcp-cli run-tool terrain-set-neighbors --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool terrain-set-neighbors --input-file - <<'EOF'
{"param": "value"}
EOF

Troubleshooting

If unity-mcp-cli is not found, either install it globally (npm install -g unity-mcp-cli) or use npx unity-mcp-cli instead. Read the /unity-initial-setup skill for detailed installation instructions.

Input

Name	Type	Required	Description
gameObjectRef	any	Yes	Reference to the center Terrain GameObject.
leftRef	any	No	Optional GameObject hosting the left neighbor Terrain.
topRef	any	No	Optional GameObject hosting the top neighbor Terrain.
rightRef	any	No	Optional GameObject hosting the right neighbor Terrain.
bottomRef	any	No	Optional GameObject hosting the bottom neighbor Terrain.
