AI ProBuilder
AI-powered 3D modeling tools that extend Unity ProBuilder, enabling natural language commands to create and manipulate editable meshes. Generate primitive shapes, extrude faces, bevel edges, apply materials, and perform advanced operations like bridging and subdivision. Features semantic face selection by direction for intuitive editing, ideal for rapid level prototyping and procedural geometry generation.
