QUBIC - Modular Builder

QUBIC is a fast and intuitive editor tool for constructing architectural designs in Unity using modular prefabs. QUBIC lets you draw rooms like in a map editor, and builds the entire structure around them: walls, floors, doors, windows, stairs, props and furniture. Just draw or move rooms in the scene view - everything updates instantly. Doors and passages are placed automatically, furniture spawns according to rules, and multi-story buildings stay connected by logic, not by hand. No need to place each wall, align doorways, or manually decorate interiors - QUBIC handles the structure so you can focus on your ideas. ⚡ Fast & Interactive Building - Draw rooms and corridors directly in the scene - Instant live updates on any change (movement, resize, style) - Smart room logic automatically places doors, arches, rails, windows 🏗 Modular Construction - Grid-based snapping for accurate placement - Supports multi-floor structures, with logic across levels - Customizable room styles with easy switching 🪑 Interior Generation - Rule-based furniture spawning (curtains, beds, carpets, etc.) - Auto prop placement per room/floor - Support for bridges, balconies, atriums, rails, fences, rooftops 🧠 Smart Prefab System - One-click prefab setup using tag rules - no coding - Edit prefabs directly in-place and see instant updates - Style override for individual rooms or entire buildings 🧭 Advanced Tools - Debug view for placement rules and cell logic - Different door/connection strategies (e.g., labyrinth, tree, fully connected) - Isometric view support for easier 2.5D game layout Designed For - Level designers working with modular kits - Game prototypes that need quick interior spaces - Dungeon/corridor design tools - Architectural previsualization 🚩[Discord] 🚩[Online Documentation] 🚩[Offline PDF]
