Modern Beta Forge Rivers
by b3spectacled
Modern Beta Forge Rivers adds river generation to worlds made with the Modern Beta Forge add-on, and is set up through its world customization screen.
What it does
Rivers are generated only when the world uses the modernbeta level type, which is entered without quotes in server.properties, and its generator options string is built in the in-game GUI. Once the add-on tab of the world customization screen is opened, a river generation tweak can be enabled and several of its settings adjusted. Modern Beta Forge must be installed, as the required dependency, and the environment is client and server, so both sides need the mod. Files target 1.12.2 only, with the latest Forge build, 1.12.2-1.10.0.0, dated 2026-09-09, and the code is under the MIT License, making it open source.
