SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

ProBuilder is a powerful Unity tool, but setting up and editing mesh geometry manually for every prototype slows iteration. This Skill automates and streamlines ProBuilder workflows inside Unity, enabling rapid, reliable mesh creation and modification during development.

Core Features & Use Cases

  • Create parametric ProBuilder shapes (Cube, Sphere, Cylinder, etc.)
  • Extrude faces and bevel edges to craft complex forms
  • Batch-create multiple shapes for level blocks or props
  • Undo-safe, automatic ToMesh/Refresh updates
  • Uses the com.unity.probuilder package for production workflows
  • Use Case: rapidly prototype a room or object by generating a set of builder shapes and refining them in editor

Quick Start

Create a basic ProBuilder cube using the Create Shape operation with shape set to Cube and default dimensions.

Frequently Asked Questions about unity-probuilder

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

FAQPage Schema
How do I automate ProBuilder mesh creation in Unity for rapid 3D prototyping?▼

You can automate ProBuilder mesh creation in Unity by using this Skill to generate parametric shapes like Cube, Sphere, and Cylinder. It handles automatic ToMesh and Refresh updates, streamlining rapid 3D prototyping without manual geometry setup.

Can I batch-create ProBuilder shapes for Unity level blocks and props?▼

Yes, you can batch-create multiple ProBuilder shapes for Unity level blocks and props. This allows you to rapidly prototype rooms or objects by generating a set of builder shapes and refining them directly in the editor.

Do I need the com.unity.probuilder package to automate mesh editing in Unity?▼

Yes, you need the com.unity.probuilder package installed in your Unity project to use this Skill. It relies on this package for production workflows to automate face extrusion, edge beveling, and mesh design.

What is the best way to extrude faces and bevel edges on Unity ProBuilder meshes?▼

The best way to extrude faces and bevel edges on Unity ProBuilder meshes is to automate the process through this Skill. It crafts complex forms by applying these operations while maintaining undo-safe updates and built-in error handling.

Why does my ProBuilder mesh not update automatically after editing in Unity?▼

ProBuilder meshes may not update if automatic ToMesh and Refresh calls are missing after editing. This Skill includes built-in safeguards to ensure these updates trigger automatically, preventing manual refresh errors during prototyping.
