SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires unity-mcp-cli.

What problem does it solve? Manually connecting separate parts of ProBuilder geometry or filling gaps between edges in Unity is tedious and error-prone. This Skill automates the creation of a new face between two specified edges on a ProBuilder mesh. ## Core Features & Use Cases - Edge Bridging: Creates a quad face connecting two edges defined as vertex index pairs, such as edgeA=[0,1] and edgeB=[4,5]. - Non-Manifold Support: Optionally allows creation of non-manifold geometry where edges are shared by more than two faces. - Detailed Result Reporting: Returns the new face index along with before/after face counts and total vertex and edge counts. - Use Case: When building a level in Unity, you have two separate wall segments with a gap between them; use this Skill to bridge the gap by specifying the bordering edges of each segment. ## Quick Start Ask the AI to bridge edges [0,1] and [4,5] on your ProBuilder GameObject to fill the gap between them.

Frequently Asked Questions about probuilder-bridge

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I connect two edges in a ProBuilder mesh in Unity?▼

Use the probuilder-bridge tool through unity-mcp-cli by providing a GameObject reference and two edges as vertex index pairs, such as edgeA=[0,1] and edgeB=[4,5]. The tool creates a new quad face between the edges and returns the new face index.

How to fill a gap between two parts of ProBuilder geometry?▼

Identify the bordering edges on each geometry part as vertex index pairs, then call the bridge operation with those edges. The tool generates a face spanning the gap and reports updated face, vertex, and edge counts.

What is non-manifold geometry in ProBuilder bridging?▼

Non-manifold geometry occurs when an edge is shared by more than two faces. The bridge tool rejects this by default, but setting allowNonManifold to true permits creating such faces when your mesh topology requires it.

Why is unity-mcp-cli not found when running ProBuilder tools?▼

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

How do I reference a GameObject for ProBuilder mesh editing?▼

Provide a GameObjectRef with the instanceID of the object, or alternatively its hierarchy path, name, asset path, or asset GUID. The target GameObject must have a ProBuilderMesh component attached.
