World Gen Config lets you shape the overworld with sliders before you create a world. It adjusts vanilla generation, so biomes, structures and features still work.
Switches: No Caves, No Rivers, No Mountains, No Oceans
Sliders:
- Temperature: colder or warmer biomes
- Continent & Ocean Size, Land vs. Ocean Balance
- Ocean Height (sea level) and Ocean Depth
- Mountain Height and Mountain Length
- Build Limit up to Y 2032, auto-raised for tall mountains
- Bedrock Depth down to Y -2032, with Lava Level
- Cave Density and Cave Size
- River Density and River Size
Open Mods > World Gen Config > Config. Each world keeps the settings it was created with.
Server-side only: players without the mod can join. Tested with Distant Horizons and Cold Sweat. Terrain overhaul mods like Tectonic may override some sliders.
Requires Minecraft 1.21.1 and NeoForge 21.1.
