Heightmap Level Generator vs MapMagic 2

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.

MapMagic 2 is a node-based procedural generator for Unity terrain and game objects. Users build graphs from generator nodes such as noise, Voronoi, blending, curves, and erosion. Listed outputs include height, holes, textures, grass, custom outputs, objects, splines, and biomes. During play mode, it can generate new terrain tiles for endless maps. The Biomes and Functions module blends graphs using masks and moves complex generation into sub-graphs. MapMagic 2 is listed as compatible with Unity 2022.3.62f1 across Built-in, URP, and HDRP render pipelines; installation requires the.NET 4.x API Compatibility Level in the Unity Editor. The core asset costs nothing. Biomes and Functions costs $45, paid once and requires an existing MapMagic 2 installation. The bundle costs $157.50, paid once and includes MapMagic 2 with Objects, Splines, Biomes, and Brush modules. The bundle listing says full source code is included. Special nodes are named for CTS, MegaSplat, MicroSplat, and Vegetation Studio Pro, though full compatibility is not guaranteed.
