# Subdivide edges in a ProBuilder mesh
|
|
|
|
Insert new vertices on selected edges of a `ProBuilderMesh`, subdividing each into smaller segments. Useful for adding detail to specific edges for further manipulation (extrude, bevel, etc.).
|
|
|
|
## Inputs
|
|
|
|
- `gameObjectRef` — the GameObject hosting the `ProBuilderMesh` component.
|
|
- `edges` — explicit list of edges to subdivide, each as `[vertexA, vertexB]`. Use 'probuilder-get-mesh-info' to discover valid edges.
|
|
- `faceDirection` — semantic alternative: subdivides all edges of faces pointing this direction (`Up`, `Down`, `Left`, `Right`, `Forward`, `Back`). Exactly one of `edges` / `faceDirection` is required.
|
|
- `subdivisions` — number of subdivisions per edge. `1` splits each edge in half, `2` into thirds, and so on. Default `1`.
|
|
|
|
## Examples
|
|
|
|
- Subdivide all edges of the top face: `faceDirection="up"`, `subdivisions=2`.
|
|
- Subdivide specific edges: `edges=[[0,1], [2,3]]`, `subdivisions=1`.
|
|
|
|
## How to Call
|
|
|
|
```bash
|
|
unity-mcp-cli run-tool probuilder-subdivide-edges --input '{
|
|
"gameObjectRef": "string_value",
|
|
"edges": [],
|
|
"faceDirection": "string_value",
|
|
"subdivisions": 0
|
|
}'
|
|
```
|
|
|
|
> For complex input (multi-line strings, code), save the JSON to a file and use:
|
|
> ```bash
|
|
> unity-mcp-cli run-tool probuilder-subdivide-edges --input-file args.json
|
|
> ```
|
|
>
|
|
> Or pipe via stdin (recommended):
|
|
> ```bash
|
|
> unity-mcp-cli run-tool probuilder-subdivide-edges --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` | `string` | Yes | Reference to the GameObject with a ProBuilderMesh component. RQL: GameObjectRef |
|
|
| `edges` | `array` | No | Array of edge definitions. Each edge is [vertexA, vertexB]. Use ProBuilder_GetMeshInfo to get vertex indices. |
|
|
| `faceDirection` | `string` | No | Semantic face selection - subdivide all edges of faces facing this direction. |
|
|
| `subdivisions` | `integer` | No | Number of subdivisions per edge. 1 = splits edge in half, 2 = splits into thirds, etc. Default is 1. |
|
