MapMagic 2 vs WorldEngine

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.

WorldEngine is free, MIT-licensed software for procedural world generation. It models processes such as plate simulation, rain shadows, erosion, humidity, and terrain permeability to generate world data and images. Outputs include elevation, precipitation, temperature, biome, and ocean maps, as well as heightmaps and biome maps. Users can set a seed, and the command line can create an ancient-looking map from a world file. Worlds can be saved in protobuf or HDF5 formats; HDF5 support requires the optional h5py dependency. Python applications can load world files using WorldEngine as a library, while Java applications can use WorldEngine-Java. Installation instructions cover Docker, source, and uv, but the package is not currently released on PyPI. WorldEngine requires Python 3.9 or later and supports versions through 3.14. A separate graphical interface is available as an experimental, limited project. The project invites questions, suggestions, and contributions through its Google group or by opening an issue.
