unity-probuilder

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.

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.

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.

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.

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.

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.
