What problem does it solve? Building level geometry in Unity with plain primitives produces non-editable meshes, forcing designers to restart when layouts change. This Skill creates and edits ProBuilder meshes directly in the editor so level blockouts, ramps, stairs, and furniture can be refined iteratively without leaving the scene. ## Core Features & Use Cases - Parametric Shape Creation: Generate cubes, cylinders, stairs, arches, and more via probuilder_create_shape, or batch-create entire blockouts with probuilder_create_batch. - Face, Edge, and Vertex Editing: Extrude, delete, merge, and bevel faces, bridge edges, weld or move vertices, and project UVs for precise geometry refinement. - Material and Color Assignment: Apply quick prototype colors or material assets to whole objects or selected faces for gameplay-role color coding. - Use Case: Block out a platformer level by batch-creating floors and platforms, verify jump distances against gameplay scale rules, then shape a ramp by moving vertices and color-code hazards before art production. ## 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.
