wiget's worldgen config (wwc)
by wiget
wiget's worldgen config changes how deep dark biomes, dappled forests and mountains generate, and it is a server-side world generation tweak.
What it does
Rarer deep dark biomes and much rarer ancient cities are the main change, and ancient cities end up roughly as common as woodland mansions. Most deep dark biomes that touch each other still contain at least one ancient city. Dappled forests generate at T1 H2 positive weirdness, which adds them beside forests and taigas and makes them a bit more common, and they can also generate on plateaus.
Mountains no longer stop at y=256 and can reach the height limit, with the highest peaks found at y=315. Minimal-impact tweaks fix some issues with vanilla worldgen. Compensation for the rarer ancient cities comes through Swift Sneak and traded librarians, and the enchanted treasure still exists. Seedfinders and seedviewers mostly still work with the datapack's deep dark and dappled forest biomes, though some positions differ, and a mostly accurate map is available to view.
Only the server needs to run it, and players may add it or leave it out. The mod is published for Fabric, Forge, NeoForge and Quilt, and as a data pack, for 26.3 only, with snapshot builds also published. It is released under the Apache License 2.0, and the source code and issue tracker are public.
Key features
Rarer deep dark biomes
Deep dark biomes appear much less often, and ancient cities inside them are made much rarer.
Dappled forest placement
Dappled forests generate beside forests and taigas, and on plateaus, at a slightly higher frequency.
Taller mountains
Mountain terrain is no longer cut off at y=256 and can reach the world height limit.
Minimal vanilla fixes
A small set of tweaks corrects several existing vanilla worldgen issues without reworking the terrain.

How it compares
Biome Rebalance is server-side and MIT licensed, and it is published for 26.3 across the four loaders, so it covers a similar biome-balance purpose. qrafty's Dappled Villages is released under Creative Commons Attribution Non Commercial 4.0 and also targets 26.3, focusing on dappled village changes rather than the forest and mountain changes here. Worldgen Patches is open source under the MIT License, but it is server-side only and covers 1.21 – 26.2 on Fabric and NeoForge, so it does not reach 26.3.
