Inserts new edges connecting the midpoints of selected edges within faces. If a face has more than 2 edges to connect, a center vertex is added. This is useful for creating new edge loops and adding geometry detail. Examples: - Connect opposite edges of top face: faceDirection="up" - Connect specific edges: edges=[[0,1], [2,3]]
unity-mcp-cli run-tool probuilder-connect-edges --input '{
"gameObjectRef": "string_value",
"edges": "string_value",
"faceDirection": "string_value"
}'
For complex input (multi-line strings, code), save the JSON to a file and use:
unity-mcp-cli run-tool probuilder-connect-edges --input-file args.jsonOr pipe via stdin (recommended):
unity-mcp-cli run-tool probuilder-connect-edges --input-file - <<'EOF' {"param": "value"} EOF
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.
| Name | Type | Required | Description |
|---|---|---|---|
gameObjectRef | any | Yes | Reference to the GameObject with a ProBuilderMesh component. |
edges | any | No | Array of edge definitions. Each edge is [vertexA, vertexB]. Use ProBuilder_GetMeshInfo to get vertex indices. |
faceDirection | any | No | Semantic face selection - connect edges of faces facing this direction. |
