Heightmap Level Generator vs TerraWorld 2023

Heightmap Level Generator creates procedural terrain and heightmaps in a browser for Unreal Engine, Unity and Godot. Its GPU-based generation uses WebGPU compute shaders and WGSL. Outputs include 16-bit heightmaps with features such as cliffs, hills, mountains, erosion, rivers, lakes and a raised border ring. It can also generate connected roads, towns, map exits, road grades and embankments around water, with temperate, steppe, desert and snow world biomes. Users can adjust settings live, compare 12 seeds, preview a 2D map and 3D mesh, and walk through terrain in first person. Exports include engine-specific terrain formats, Web or three.js formats, heightmaps, splatmaps, masks, water levels, color maps, layout JSON, glTF meshes and metadata JSON. Road, town and water masks and layout data can support PCG, Houdini and custom placement scripts. The free project supports share links, presets, JSON save and load, and undo and redo. Online use requires a WebGPU-capable browser; local use requires Node.js and such a browser.
