UHC World Gen Datapack

This datapack tweaks Minecraft world generation for a better UHC game.

It's also intended to be a template for anyone who wants to customize their world generation, because the datapack format is definitely tricky.

This pack was made for version 1.21.4, but should work on 1.21.x and future versions. If breaking changes happen, please make an issue and I will try to update it!

Features

• No oceans (large-ish rivers still generate)
• Increased frequency of small caves
• Less extreme mountains and hills
• World bottom moved to -32 instead of -64
• Rebalanced generation of ores (you can further customize this yourself too)

See FEATURES.md on my GitHub for a full list of features and how to customize them.
