Dungeon Builder turns a seed into a complete, playable level: crypts, sewers, office towers, cities, caves, platformers and whole islands with villages and quests. Swap the theme and the same layout becomes a new place.
Generation is split in three clean stages, so level design and art stay independent. Change one without touching the others.
1
A builder plans the layout
Pick a builder (Grid, Snap, Grid Flow, WFC, Regions…), set a seed and its rules. It computes rooms, corridors, stairs, doors, keys and locks in memory, in milliseconds.
2
It emits markers
Every cell becomes semantic markers: Ground, Wall, Door, Stair, Corner… Inspect them live with the Marker Debugger.
3
A theme dresses it
A node graph maps each marker to prefabs, with probabilities, constraints, scatter nodes and pattern rules. One layout, any art style: stone crypt, snowy forest or candy land.
Builders
One toolkit, every kind of level.
From tight dungeon crawls to kilometre-wide open worlds. Every builder ships with playable samples you open from the Launch Pad in one click.
Grid Flow
Keys, locks & flow graphs
Author the mission as a graph (main path, branches, loops, keys and locks), then let it unfold on a grid.
Maze
Labyrinths
Backtracker mazes with rooms, dead-end treasures, a key far from the locked exit and a minimap.
Regions
Halls with rooms inside
Huge halls packed with L, T and U rooms, holes to the floor below, bridges and up to four stacked floors.
Snap Grid Flow
Hand-made rooms, snapped
Design rooms in the Room Designer, then let a flow graph assemble them over several floors.
Cell Flow
Organic Voronoi rooms
Irregular cells with a main path, branches, terraces and double stairs, dressed with any Grid theme.
WFC
Wave Function Collapse
Define tiles and adjacency rules, watch the solver step by step, and keep the seeds you like.
Grid · Snap · Snap Flow
Classic dungeons
Rooms and corridors with heights and stairs, BSP or graph grammars, prefab modules snapped by their doors.
Biome World
Islands in four biomes
Meadow, forest, desert and tundra up to 1 km wide, seamless multi-terrain, hamlets and cave entrances, streamed around the player.
Terrain Generator
Mountains, coasts, erosion
Ridged mountains, hydraulic erosion, beaches, rock and snow layers, forests and lakes from a single seed.
Road Network · Village
Roads, rivers & hamlets
Road networks that follow the land, rivers with bridges, and villages with furnished house interiors.
Grid Flow
Outdoor arenas
Forest edges as walls, large grids with many loops; the winter variant comes with living snowmen.
City
Towns & cities
Streets with markings, houses, towers and parks; desert and cartoon themes included.
Floor Plan
Multi-storey buildings
Floor plans split into rooms and corridors over several storeys, furnished one item per cell.
Pipe
Pipe networks
Pipes routed around boilers, tanks and pillars, with elbows, valves and gauges. Combine with Grid for full plants.
Voxel Caves
Smooth voxel caverns
Multi-level caves joined by ramps, glowing crystals, or endless caves streamed in at runtime.
Infinity Caves
Infinite cave chunks
Chunk-based caves with cellular automata, stalactites, glowing mushrooms and a campfire per chunk.
Mario
Side-scrolling platformers
Ground, gaps, bonus blocks, pipes and patrolling enemies, with a platformer player and side camera.
Grid 2D
Top-down 2D
Pixel-art sprites, a twin-stick player that aims with the mouse, and enemy spawners.
Visual editors
Everything editable, nothing hidden in code.
Thirteen dedicated windows cover the whole pipeline, from theme graphs to quests. Every editor shows a live preview and supports seeds and favourites.
Playable out of the box
Press Play and walk your level.
Add the Test Player and every sample becomes a small game: explore, fight, loot, talk to villagers and finish quests. Press N for a brand new level.
Quests, dialogue & merchants
Quest givers with branching dialogue, rewards and reputation, a quest journal, a compass and shops in every hamlet.
Ready for standalone VR budgets
Three Meta Quest 3 samples tuned for draw calls and triangles, with an audit tool for your own scenes.
Living props
Elevators, conveyors, forklifts and machines that never block a stair or a door.
Open-world streaming
Only what is around the player is loaded, with progress screens and runtime generation.
Mesh merging
Merge static geometry per material to keep draw calls low on large levels.
HUD, inventory & hotbarHealth, lives, gold, coloured keys, potions and ammo, kept across levels.
Enemies with AIPatrol, chase and attack, with vision cones, health and animations.
WeaponsCarbine, rifle and pistol with aiming, reload, crosshair and hit effects.
Save & loadGame state snapshots with F5 / F9, ready to plug into your own save system.
Co-op multiplayerOptional Netcode for GameObjects sync: every client builds the same dungeon.
Requirements
