probuilder-bevel - SKILL.md Agent Skill

name: probuilder-bevel description: |- Bevels selected edges of a ProBuilder mesh, creating chamfered corners. Use ProBuilder_GetMeshInfo to identify edges by their vertex pairs. Beveling replaces sharp edges with angled faces for a smoother appearance.

Bevel ProBuilder edges

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.
