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 BuildingDraw rooms and corridors directly in the sceneInstant live updates on any change (movement, resize, style)Smart room logic automatically places doors, arches, rails, windows🏗 Modular ConstructionGrid-based snapping for accurate placementSupports multi-floor structures, with logic across levelsCustomizable room styles with easy switching🪑 Interior GenerationRule-based furniture spawning (curtains, beds, carpets, etc.)Auto prop placement per room/floorSupport for bridges, balconies, atriums, rails, fences, rooftops🧠 Smart Prefab SystemOne-click prefab setup using tag rules - no codingEdit prefabs directly in-place and see instant updatesStyle override for individual rooms or entire buildings🧭 Advanced ToolsDebug view for placement rules and cell logicDifferent door/connection strategies (e.g., labyrinth, tree, fully connected)Isometric view support for easier 2.5D game layoutDesigned ForLevel designers working with modular kitsGame prototypes that need quick interior spacesDungeon/corridor design toolsArchitectural previsualization[Discord] [Documentation]Before You BuyThis is an editor-only tool for manually drawing buildings, mazes, or dungeons.This tool is not intended for drawing buildings or generating levels at runtime.Requires your own modular prefab set (walls, floors, doors, etc.)While Qubic is compatible with most prefab types, certain prefab sets may not be fully compatible. Also, in some cases, specialized prefabs, like columns for wall corner connections, may be needed to achieve optimal results.PerformanceAll updates are real-time - even buildings with thousands of cells update in milliseconds. You can have multiple buildings in a single scene, each with separate settings and styling.Rule-Based SpawningPrefab logic is driven by tags and naming - no code needed. You define spawn behavior based on placement type, floor number, and room style, allowing consistent and predictable results. At the same time, it is a very flexible and extensible tool. You can write own spawn logic via API.
