3D Dungeon Generator vs Gaea

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.

Gaea is a Windows terrain design application for VFX, games, and virtual production. It builds terrain from procedural forms, imported data, or hand-drawn elements, then applies simulations for erosion, debris, glaciers, rivers, snow, and vegetation. It can produce terrain-aware color, textures, masks, material zones, vegetation data, and flow maps. Exports include heightfields, meshes, point clouds, textures, masks, and other terrain data. Bridges connect Gaea with Unreal Engine and Houdini; the Gaea2Houdini plugin requires a Professional or Enterprise license. Gaea also offers node-based compositing and a hybrid render engine.

The Community Edition is free for non-commercial use. The listed perpetual-license prices are $99 a month for Indie, $199 a month for Professional, and $299 a month for Enterprise; each is described as a one-time price. Gaea requires Windows, an AVX2-capable CPU, and at least 16 GB of RAM. CPU-only operation is supported; GPU compute needs CUDA 12.5 or higher or HIP 6.0 or higher.
