JJThunder To The Max Mod changes how your Minecraft world generates. It builds giant mountains that reach up to 2000 blocks into the sky. Even with these huge peaks, the mod still leaves flat plains at the bottom for you to walk on. It also updates the caves underground to match the giant size of the world above.

Features:

  • Giant Mountains: This mod creates huge mountains that reach up to 2000 blocks high.
  • Flat Plains: You will find wide, flat areas right at the bottom of the giant mountains.
  • New Caves: Changes the underground caves to fit the huge size of the new world above.
  • The JJThunder To The Max Mod completely changes how the game builds the terrain to give you a realistic world size.
  • Needs a strong computer and extra RAM to load the huge world without lag.
  • Breaks old builds, so you must start a brand new world to play safely.
  • Stops working if you try to mix it with other world generation packs like Terralith or Tectonic.
  • Works a little bit with custom biome mods, but you might still see some small errors.
