Heightmap Level Generator

Purpose: Heightmap Level Generator creates procedural terrain and heightmaps for Unreal Engine, Unity and Godot in a browser.
GPU generation: Terrain is generated on the GPU with WebGPU compute shaders and WGSL.
Terrain output: The generator produces 16-bit heightmaps with cliffs, hills, mountains, erosion, rivers, lakes and a raised border ring.
Roads and towns: It generates connected road networks, towns, map exits, road grades and embankments around water.
Biomes: Four biomes are available: temperate, steppe, desert and snow world.
Interactive editing: Users can adjust settings live, compare 12 seeds, preview a 2D map and 3D mesh, and walk through the terrain in first person.
Engine exports: Exports include Unreal landscape, Unity terrain, Godot Terrain3D and Web or three.js formats.
Export files: Exports can include 16-bit PNG or RAW heightmaps, splatmaps, masks, water levels, color maps, layout JSON, glTF meshes and metadata JSON.
Tool integrations: Road, town and water masks and layout JSON are intended for PCG, Houdini and custom placement scripts.
Sharing and presets: The application supports URL share links, JSON save and load, undo and redo, and built-in terrain presets.
Platform requirement: The online version requires WebGPU, such as a current desktop Chrome or Edge browser.
Local use: The project can run locally with Node.js and a WebGPU-capable browser, and its Windows start.bat script runs the setup.
License and ownership: The project is MIT licensed, exports can be used, changed and shipped commercially, and exported assets belong to the user without conditions.
