probuilder-bevel	Bevel (chamfer) selected edges of a `ProBuilderMesh`, replacing each sharp edge with an angled face. Identify edges by their `[vertexA, vertexB]` index pairs — use 'probuilder-get-mesh-info' to discover them. `amount` is clamped to (0, 1).	generated-by mcp-plugin-dotnet

Bevel ProBuilder edges

Bevel (chamfer) selected edges of a ProBuilderMesh, replacing each sharp edge with an angled face for a smoother appearance. Use 'probuilder-get-mesh-info' first to discover edges by their vertex pairs.

Inputs

• gameObjectRef — the GameObject hosting the ProBuilderMesh component.
• edges — array of edge definitions; each edge is [vertexA, vertexB]. Example: [[0,1], [2,3]] bevels two edges.
• amount — bevel strength in the range (0, 1). 0.001 is barely visible, 0.999 reaches face center. Recommended 0.05–0.2. Internally clamped.

Behavior

Vertex indices are validated against vertexCount. After BevelEdges runs, the mesh is rebuilt (ToMesh → Refresh), the ProBuilderMesh and GameObject are marked dirty, and Editor windows repaint. Returns the number of edges processed, the clamped amount, and post-op face/vertex/edge counts. The whole call runs on the Unity main thread.

How to Call

unity-mcp-cli run-tool probuilder-bevel --input '{
  "gameObjectRef": "string_value",
  "edges": "string_value",
  "amount": 0
}'

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

unity-mcp-cli run-tool probuilder-bevel --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool probuilder-bevel --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 GameObject with a ProBuilderMesh component.
edges	any	Yes	Array of edge definitions. Each edge is defined by two vertex indices [vertexA, vertexB]. Example: 0,1], [2,3 bevels edges from vertex 0 to 1 and from vertex 2 to 3.
amount	number	No	Bevel amount from 0 (no bevel) to 1 (maximum bevel reaching face center). Recommended values: 0.05 to 0.2.
