3D Dungeon Generator vs World Machine

3D Dungeon Generator makes procedural, solvable room-and-corridor dungeons in a browser. It places rooms without overlap and connects them with carved corridors; users can adjust room count, room size, and corridor width. A seed and its settings can reproduce the same layout, including a route from entrance to exit, with optional extra corridor links. The real-time preview supports orbiting, a top view, fit controls, and first-person walking from the entrance. Themes include Stone, Backrooms, Dungeon, Concrete, Sci-Fi, and Hedge, and users can supply wall, floor, and ceiling textures. GLB export includes the dungeon geometry and current materials, with options for a ceiling and solution path. Custom texture support in exported GLB depends on browser image decoding. The tool is free at free, browser-based, and requires no signup or subscription. Dungeon sizes range from 16×16 presets to custom dimensions up to 60×60. LevelRift Labs lists uses such as game level prototyping, game jams, dungeon concepts, and Blender or other GLB-compatible workflows. The product page says original texture files are not uploaded by the app.

World Machine is procedural 3D terrain-generation software for artists creating realistic or stylized landscapes, including game, film, and visualization work. Its node graph offers more than 100 devices for terrain, erosion, rivers, masks, materials, and outputs. Simulations cover flow-based and thermal erosion, snow accumulation, river channels, lakes, and coastal erosion; Dragontail Peak adds terrain with overhangs, cliff faces, and caves. Exports include heightfields, meshes, masks, and PBR textures in standard formats, with listed file types including RAW, EXR, TIFF, PNG, TER, OBJ, glTF, and GLB. Compatible tools named by the maker include Unreal Engine, Unity, Godot, Blender, Maya, and Cinema 4D. Professional and higher editions support tiled builds for worlds larger than memory and can resume builds after interruption. The free Basic edition has the Indie toolset but caps each output asset at 1025×1025 pixels and is limited to non-commercial use. Paid plans are Indie at $119 a month, Professional at $299 a month, and Studio Site at $1,999 a month. It runs on Linux, macOS, and Windows.
