SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill removes the friction of building and editing editable Unity geometry when you need fast blockouts, reliable grayboxing, and precise topology changes instead of fixed primitive objects.

Core Features & Use Cases

Editable ProBuilder creation: Create cubes, ramps, stairs, doors, and other parametric shapes that remain editable in Unity.
Topology refinement: Extrude, bevel, bridge, merge, delete, and move vertices or faces to shape level geometry with control.
Blockout workflow: Build rooms, corridors, platforms, ramps, and traversal paths while keeping gameplay scale and reachability in mind.
Prototype props: Assemble simple furniture and environment pieces from multiple ProBuilder parts for cleaner silhouettes and faster iteration.

Quick Start

Use the unity-probuilder skill to block out a small Unity level with editable ProBuilder geometry, including a floor, walls, and a ramp, then refine the shape for gameplay traversal.

FAQPage Schema

How do I create editable Unity meshes for level blockout?▼

To create editable Unity meshes for level blockout, use the unity-probuilder skill to generate cubes, ramps, and stairs that remain editable. It applies topology refinement operations like extrude, bevel, and vertex movement to shape level geometry without fixed primitives.

What is greyboxing in Unity and how does it handle topology?▼

Greyboxing in Unity is the process of building rapid prototype level geometry while keeping topology editable. This Skill supports greyboxing rooms, corridors, and platforms by applying face, edge, and vertex operations to ensure precise topology changes during iteration.

Do I need the com.unity.probuilder package to block out Unity levels?▼

Yes, you need the com.unity.probuilder package installed to block out Unity levels with this Skill. It requires the package to support batch shape creation, UV projection, material assignment, and detailed mesh editing operations.

Can I extrude and bevel faces in Unity ProBuilder meshes?▼

Yes, you can extrude and bevel faces in Unity ProBuilder meshes. The Skill supports topology refinement including extrude, bevel, bridge, merge, and delete operations, allowing precise control over vertices and faces for detailed level geometry.

What's the best way to prototype Unity environment props without fixed primitives?▼

The best way to prototype Unity environment props without fixed primitives is assembling simple furniture from multiple editable ProBuilder parts. This approach provides cleaner silhouettes and faster iteration compared to using fixed primitive objects.

Why use editable ProBuilder meshes instead of standard Unity primitives for level design?▼

Use editable ProBuilder meshes instead of standard Unity primitives for level design when you need reliable greyboxing and topology changes. Standard primitives lack editable vertices and faces, making them unsuitable for precise traversal layout and blockout workflows.
