SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires unity-mcp-cli.

What problem does it solve? Manually chamfering sharp edges on ProBuilder meshes in Unity is tedious and error-prone, especially when you need to target specific edges by vertex indices. This Skill automates the bevel operation through the unity-mcp-cli, replacing sharp edges with angled faces in a single command. ## Core Features & Use Cases - Targeted Edge Beveling: Bevel specific edges identified by vertex index pairs (e.g., [[0,1], [2,3]]) on any GameObject with a ProBuilderMesh component. - Adjustable Bevel Amount: Control the chamfer depth from 0 to 1, with recommended values between 0.05 and 0.2 for natural-looking corners. - Structured Result Reporting: Returns counts of beveled edges, newly created faces, and updated totals for faces, vertices, and edges. - Use Case: While prototyping a level blockout in Unity, select a platform mesh and bevel its top edges by 0.1 to soften the silhouette before playtesting. ## Quick Start Ask the AI to bevel edges [[0,1]] and [[2,3]] of your ProBuilder mesh GameObject by 0.1 using the probuilder-bevel tool.

FAQPage Schema
How do I bevel edges on a ProBuilder mesh in Unity?

Run the probuilder-bevel tool through unity-mcp-cli with a gameObjectRef pointing to the GameObject, an edges array of vertex index pairs like [[0,1],[2,3]], and an amount between 0 and 1. The tool replaces the sharp edges with angled faces.

How do I find edge vertex indices for ProBuilder beveling?

Use the ProBuilder_GetMeshInfo tool to inspect the mesh and identify edges by their vertex pairs. Each edge is then passed as a two-element integer array of vertex indices to the bevel tool.

What bevel amount should I use for ProBuilder edges?

The amount ranges from 0 (no bevel) to 1 (maximum bevel reaching the face center). Values between 0.05 and 0.2 are recommended for subtle, natural-looking chamfers.

Why is unity-mcp-cli not found when running the bevel tool?

The CLI is either not installed or not on your PATH. Install it globally with npm install -g unity-mcp-cli, or invoke it with npx unity-mcp-cli instead.

Can I bevel multiple edges of a ProBuilder mesh at once?

Yes, pass multiple vertex pairs in the edges array, such as [[0,1],[2,3],[4,5]]. The response reports how many edges were beveled and how many new faces were created.
