What 3D Dungeon Generator is

3D Dungeon Generator is a browser-based tool for creating procedural 3D dungeons from rooms and corridors. Adjust room count, room size and corridor width; the generator places rooms without overlap and carves connecting routes. Dungeon dimensions range from 16×16 presets to custom sizes up to 60×60. Set a seed to recreate the same layout with the same settings, including an entrance-to-exit route, and optionally add extra corridor connections. A real-time preview offers orbit, top view, fit controls and a first-person walk from the entrance. Themes include Stone, Backrooms, Dungeon, Concrete, Sci-Fi and Hedge; custom wall, floor and ceiling textures are also supported. Export geometry and current materials as GLB, with options for a ceiling and solution path. Custom textures in GLB exports depend on browser image decoding. The maker says original texture files are not uploaded. The tool is free, requires no signup or subscription, and is intended for prototyping, game jams, dungeon concepts and GLB-compatible workflows.
