Dungeon Architect

What Dungeon Architect is

Dungeon Architect is a procedural level generator for Unreal Engine and Unity. Its node graphs define paths, key-locks, one-way doors, teleporters, and boss rooms, then check whether layouts remain completable. A theme engine places meshes, lights, blueprints, and foliage by rule, allowing art-style changes without altering layout rules. Generation methods include Grid Flow, Snap Map, Snap Grid Flow, Cell Flow for grid and Voronoi layouts, and GPU Voxels. Snap Map and Snap Grid Flow combine handcrafted rooms into layouts with branches, cycles, key-locks, multiple floors, streaming, and multiplayer support. In Unreal, flow graphs can drive the PCG system, with Electric Dreams samples included. GPU Voxels is shipping in Unreal, while its Unity port is in progress. Levels can be edited manually or generated at runtime. The plugin is extendable through Blueprints and C++, and includes demos, documentation, videos, themes, and changelogs. The Unity plan costs $300, paid once.
