What's new

Volcanic Entrances

  • Rounded out underwater volcanic shafts and entrance passages.
  • Replaced repetitive spiral-like magma patterns with irregular patches.
  • Fixed shaft walls blocking the connection to the tunnel network.

Lush Caves

  • Restricted azalea bushes to the edges, keeping central paths clear for exploration and Pokémon spawning.
  • Preserved the existing glow berry density and vine lengths.

Water Tunnel Entrances

  • Replaced angular, staircase-like entrances with curved, fully flooded cave passages.
  • Added variation in passage width and height.
  • Rounded and widened openings in the seabed.
  • Prevented entrance walls from protruding above the existing seabed.
  • Fixed blocked connections between entrance passages and the main tunnel network.
  • Added cleanup for floating kelp and seagrass left unsupported during generation.
  • Added colorful coral blocks and matching waterlogged coral fans around entrances and along descending passages.

Release

  • Updated installation instructions, configuration documentation, and locate commands.
  • Validated all 44 structure variants.
  • Tested the release build and underwater entrance connectivity on a local server.

Updating: Replace the previous mod JAR. Structure and entrance changes apply to newly generated chunks; existing structures are not rebuilt automatically.
