Design the rules.
Generate infinite worlds.

Cyclic paths, key-locks, one-way doors, teleporters, boss rooms — declare the rules once, generate infinite variations that honor them.

Every layout is walked start to finish before the build completes: keys reachable, locks meaningful, no stranded players. Hide a boss key down an optional side branch, gate the treasure vault behind a one-way drop — the solver guarantees the run is always finishable.

Meshes, lights, blueprints, foliage — dropped in by rule. Swap the theme file and the same dungeon becomes a different game.

The CellFlow builder from the Unreal version: Voronoi and grid based cell layouts, controlled by a flow graph.

A PCG-style node graph for Unity that dresses dungeons and terrain with grass, rocks, props and lights, driven by rules that understand your level.

The complete sci-fi Foundry theme from the Unreal version, ported to Unity, with the Theme Editor features it needs.

Define your patterns in full 3D space. Backward compatible with the 2D version.

Grow standalone paths and control where branches leave and join. No main path needed.

The Canvas minimap framework from Unreal, with map icons and fog of war on any game object, shared across players in multiplayer.

The GPU voxel cave system from Dungeon Architect 3.0 for Unreal, coming to Unity.

One graph. Every builder.

Grid Flow, Cell Flow and Snap Grid Flow all run on the same abstract flow graph. Swap the first node — a grid or a voronoi field — and everything downstream works unchanged: paths, cycles, key-locks, validation. The final step hands the solved layout to the builder to realize its own way — tilemaps, stitched rooms, voronoi caves.

Link a prefab in the theme graph and the dungeon in your viewport updates as you edit — no rebuild, no waiting. Layer in a few more prefabs and a bare layout becomes a finished level in minutes, not days.

The node graph behind it all: meshes, blueprints, lights and NPCs dropped in by rule, with live preview as you edit. Swap the theme file — same dungeon, different game.

Hand-crafted rooms, procedurally assembled — the human touch, multiplied by the generator. Craft modules in the Room Designer or bring your own — Snap Map stitches them via graph-grammar rules, Snap Grid Flow via 3D flow graphs: cycles, branches, key-locks, multi-floor, streaming, multiplayer.

Write layout rules as graph rewrites — match a pattern, replace it, grow the mission graph: shops, key-locks, mini-bosses, teleporters. The solved graph then stitches your pre-built rooms into the level — the mission-graph structure modern roguelikes are built on, with an integrated editor to design, visualize and debug the rules.

Decorate by rule, not by hand: match patterns of walls, doors and grounds — a corner, an alcove, a dead end — and rewrite what spawns there. Complex theming that survives every regeneration.

A minimap framework with its own theme editor: stack SDF-driven layers — outlines, borders, fills, fog of war. Parchment scroll or sci-fi HUD, same dungeon underneath. Ships as an interactive UMG widget with zoom and pan.

Generate thousands of test dungeons from your graph, chart the retry distribution, and fix designs that don't converge — before your players ever see them. Override any graph parameter from the analyzer window to test tweaks without touching the base design.

Organic worlds, carved on the GPU.

The same flow graphs that lay out your dungeons now drive compute shaders. Take a blocky mesh layout and re-carve it as a living cave — stalactites, overhangs, floating islands — with full Nanite and Lumen support.

Influence the generated voxels with volumes: drop one into the level and carve your own rooms, ramps and passages straight into the terrain — here, a cave cut through an island's rock face.

Node-driven paths on a tilemap — cycles, key-locks, item placement. watch →

Stitches your hand-built rooms with graph-grammar rules.

Hand-built rooms on a 3D flow graph — multi-floor, streaming, side-scrollers. watch: mario-style platformer →

Roads, houses and large blocks — themed like everything else. watch →

The same cell layouts on a grid — rooms, corridors and multi-floor structures like the Foundry and the rig.

Voronoi layouts for organic, non-grid dungeons with dynamic height.

Organic caves and floating islands, carved by compute shaders.

Place add and subtract boolean volumes to build rooms of complex design, fast.

Grow levels from rewrite rules.

An experiment in growing layouts step by step: a heavily extended take on the MarkovJunior approach. Rooms claim space, corridors find their way, and borders seal themselves. Research, not scheduled for a release.
