Modern Beta Forge Voronoi Climates

Modern Beta Forge is required, and the add-on works through the world type it provides. Once installed, the Modern Beta world type can be customized in the world creation screen, where a preset is picked from the Presets list, or a Voronoi biome source is selected to build a custom biome map. The Biome Map editor opens from the Add-on tab, and its visual layout makes it easier to see how biomes are placed relative to each other.

Two built-in climate maps are offered: a Vanilla Climatic map that uses most vanilla biomes, and a Beta Climatic map that reproduces the biome distribution of Minecraft Beta. A new map can be started from scratch, or generated as an approximation of a climate map based on the biomes chosen. Temperature and rainfall values are built in, and certain elevation-based biomes such as hills, mountains and oceans can be excluded or adjusted through the mod's config menu. Biome size is set by changing the temperature, rainfall and detail scale values.

The mod is licensed under the MIT License and its source code is public. The server and every player need the mod installed. The generator options string can be created with the in-game GUI, then entered as the generator-settings field, and the levelType field is set to modernbeta. Files are published for Forge only, for 1.12.2, with 1.10.1.1 as the latest file.
