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.
