# Unity AI ProBuilder

A Unity Editor tool that lets an AI assistant create and edit ProBuilder meshes through natural language, covering primitive shapes, extrusion, beveling, material assignment and mesh merging.

Unity AI ProBuilder exposes ProBuilder's mesh-editing operations to AI assistants as MCP tools: creating primitive shapes such as cubes, spheres and cylinders, reading a mesh's faces, vertices and edges, extruding and beveling faces, deleting faces by index or direction, and applying materials to specific faces. Further tools flip normals, change a mesh's pivot point, merge several ProBuilder objects, subdivide or connect edges, bridge between edge selections, and build custom polygon-based meshes.

It supports semantic face selection by direction, such as up, down, left or right, for more intuitive editing without navigating the ProBuilder inspector by hand, and is built on the same AI Game Developer platform as the equivalent Unity AI Particle System tool. It installs through a downloadable Unity package or the Unity Package Manager.
