Includes ready-to-use prefabs for foundations, walls, wall variants with doors and windows, upper floors, roofs, and stairs. The system supports placement previews, snap points, multi-level building, radial build selection, resource costs, demolition, refunds, and a demo scene with camera controls.

Content is fully customizable through Build Definition assets, prefab sockets, resource settings, preview prefabs, and materials. You can add new build pieces by creating a prefab, assigning sockets, and linking it to a Build Definition.

Suitable for survival games, crafting games, base-building games, sandbox projects, strategy prototypes, and any project that needs modular construction mechanics.
