SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Building level geometry in Unity by hand is slow when you need editable meshes for blockout and greyboxing. This Skill lets you create parametric ProBuilder shapes and edit faces, edges, and vertices directly in the editor through simple skill calls. ## Core Features & Use Cases - Parametric Shape Creation: Create cubes, cylinders, stairs, arches, and more individually or in batches with probuilder_create_shape and probuilder_create_batch. - Topology Editing: Extrude, delete, merge, and detach faces, bevel and bridge edges, and move or weld vertices for ramps, slopes, and irregular silhouettes. - Materials and Querying: Assign quick prototype colors or material assets, project UVs, and inspect mesh stats with probuilder_get_info and probuilder_get_vertices. - Use Case: Block out a platformer level by batch-creating floors and platforms, verifying jump distances against gameplay scale rules, then refining ramps with vertex edits and color-coding surfaces by gameplay role. ## Quick Start Ask the AI to block out a simple level with a ground plane, two platforms, and a ramp using ProBuilder, then color the platforms blue.

Frequently Asked Questions about unity-probuilder

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

FAQPage Schema
How do I create ProBuilder shapes in Unity from a script?

Use probuilder_create_shape with a shape type like Cube, Cylinder, or Stairs plus size and position parameters. For multiple shapes, probuilder_create_batch accepts an items array and an optional default parent in one call.

How do I edit ProBuilder faces and vertices in Unity?

Query the mesh first with probuilder_get_info or probuilder_get_vertices to identify indexes, then apply edits like probuilder_extrude_faces, probuilder_delete_faces, or probuilder_move_vertices. Mesh rebuild steps are handled automatically by the skills.

Does this work without the ProBuilder package installed?

No, every skill requires the com.unity.probuilder package. If it is missing, each call returns a package-missing diagnostic instead of executing, so install ProBuilder through Unity Package Manager first.

What is the difference between probuilder_set_material and probuilder_set_face_material?

probuilder_set_material assigns a material or quick RGB color to the entire object, while probuilder_set_face_material targets selected faces by index or submesh. Use face-level assignment for multi-material surfaces.

When should I use ProBuilder instead of regular GameObjects?

Use ProBuilder when you need editable topology for level geometry, ramps, and greyboxing. For ordinary primitives without editable meshes, use gameobject_create instead, since regular meshes do not become ProBuilder meshes automatically.
