MapMagic 2 vs Worldsmith

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.

Worldsmith is a free, open-source browser application for generating fantasy world maps from a numeric seed, with a mode for rendering real Earth. Procedural terrain uses domain-warped fractal noise, including ridged mountain ranges, while biomes derive from elevation, moisture, and temperature. Rivers use D8 flow accumulation to form tributary drainage networks. Exports include PNG maps up to 5120 pixels, editable SVG maps up to 3840 pixels, JSON world data, and 8-bit or 16-bit heightmaps. The maker says heightmaps can be imported into Unity, Unreal Engine, Blender, and World Machine. Earth mode uses NOAA ETOPO1 elevation and bathymetry, averaged to about five kilometers per sample; synthesized detail is disclosed and can be disabled with Detail set to 0. The app runs entirely client-side without an account, server, or dependencies, and is offered under the MIT license.
