Voxel Plugin vs worldGen

Voxel Plugin is voxel technology for Unreal Engine, with version 2 focused on creating and generating interactive terrain. Worlds can be changed at runtime, and those changes are described as reversible and non-destructive. Terrain is authored with stamps that generate 2D height or 3D volume data; procedural generation is deterministic when the same seeds are used. Voxel Graphs provide node-based control over world generation, but are not included in the Free plan.

The plugin targets Nanite as its main rendering pipeline and supports tessellation and displacement there. Unreal Engine's PCG framework can query voxel terrain and metadata, and PCG graphs can call Voxel Graphs; foliage workflows use PCG rather than direct plugin handling. Voxel Plugin 2 does not support cubic terrain or static, pre-baked world generation. Its documented release targets Unreal Engine 5.6 and 5.7 and is actively being developed, with documentation warning it may be buggy. The Free plan is free; Pro costs $349, paid once and is not for project budgets over $200k.

worldGen is a free, open-source procedural generator for two-dimensional maps built from an integer seed. It creates continents, oceans, rivers, forests, swamps, beaches, cliffs, settlements, and roads. Terrain begins with multifractal noise and simulated raindrop erosion, while rain-shadow modeling affects climate across mountain ranges. Elevation, moisture, and temperature produce thirteen biomes. Reusing a seed generates the same world, making results repeatable. The interactive viewer supports panning, zooming, tile details, step-by-step generation visualization, and screenshot export. World state can be saved in TOML, and a world blob can be exported as a .bin file. Display and generation parameters are adjustable in config.toml, with additional settings in world/config.go. worldGen is a Go desktop application using Ebiten and requires Go 1.21 or later plus desktop OpenGL support. It runs on Linux, macOS, and Windows under the MIT license. The roadmap lists urban layouts, more plant and biome variety, waterfalls, cliffs, and artificial life.
