About d3v_c's Terrain Overhaul
From ModrinthFabric worldgen overhaul for 1.21.11: taller mountains, deeper terrain, rebalanced biome climate zones, more natural caves, and improved underwater shaping for realistic Overworld landscapes.
d3v_c's Terrain Overhaul is a Fabric worldgen mod for Minecraft 1.21.11 that redesigns the Overworld to feel larger, rougher, and more natural while staying vanilla-friendly.
### What it changes
- Reworks Overworld terrain noise (continents, erosion, ridges, depth, sloped-cheese, and base 3D noise).
- Expands world vertical generation to Y -96 to 383 (480 total height).
- Retunes cave generation (entrances, noodle, spaghetti, pillars, and cave-cheese) for more varied cave systems.
- Rebalances climate noise (temperature + vegetation) for smoother biome region transitions.
### Compatibility
- Minecraft: 1.21.11
- Loader: Fabric (0.18.4+)
- Dependency: Fabric API
- Java: 21
- Best used on a new world.
### Known limitations
- Only newly generated chunks use the new terrain.
- Existing worlds can show chunk borders where old and new generation meet.
- Incompatible with other mods/datapacks that override the same Overworld worldgen files (noise settings, density functions,
cave/climate noise, village structure files).
- No in-game config menu yet.
