Worldgen Patches
Fixes a few small issues in worldgen. Free Minecraft Java mod for 1.21.11, 1.21.1, 1.21.7.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Worldgen Patches
This mod aims to patch some minor issues/quirks with world generation. Currently, this includes the following fixes:
- The
steepsurface rule (which in vanilla gives Jagged Peaks stone faces) now affects all directions, not just the north and east-facing sides. - Snow layers correctly generate both below and on trees.
- Beached shipwrecks no longer spawn at different heights and with different block palettes across chunk borders.
- Igloos never generate a trapdoor if there is no basement.
