MapMagic 2 vs Ymir

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.

Ymir is a node-based procedural terrain generator for Linux and Windows, with a graph workflow for constructing and exporting terrain. Nodes cover noise and shape generation, sculpting, filters, and thermal, hydraulic, and stream erosion. Erosion can use a mask and produce flow, wear, and deposition layers for later terrain work. Projects are stored as readable JSON in .ymir files, and node networks can be saved for reuse as .ymirsub subgraphs. Heightmaps export as 16-bit grayscale PNG, raw 16-bit R16, or 32-bit float EXR. The headless ymir-cli can build saved projects and export results; erosion runs on a GPU when available and otherwise falls back to the CPU. The editor requires a GPU with working Vulkan drivers on Linux, or Vulkan or DX12 drivers on Windows. Ymir is free software under GPL-3.0. Windows binaries are unsigned and prompt a first-run SmartScreen warning.
