Summary
Heightmap Level Generator is a free browser-based tool for creating procedural terrain and heightmaps for Unreal Engine, Unity, and Godot. It uses WebGPU compute shaders and WGSL to generate 16-bit terrain with cliffs, hills, mountains, erosion, rivers, lakes, and a raised border ring. It can also create connected road networks, towns, map exits, road grades, and embankments around water. Four biomes are available: temperate, steppe, desert, and snow world. Users can adjust settings live, compare 12 seeds, preview a 2D map and 3D mesh, and walk through the terrain in first person. Exports include engine-specific formats, Web or three.js, heightmaps, splatmaps, masks, water levels, color maps, layout JSON, and glTF meshes. Share links, JSON save and load, undo and redo, and built-in presets are also supported. The online version requires WebGPU, such as in a current desktop Chrome or Edge browser. Local use requires Node.js and a WebGPU-capable browser. The project is MIT licensed, and exported assets may be used commercially.
