UndergroundOcean

This decorative mod completely revolutionizes the underground world of Minecraft, adding impressive flooded cave systems to various dimensions. The generation creates huge underground spaces partially filled with water, significantly diversifying subterranean exploration.

With default settings, the mod generates in the normal world relatively shallow but incredibly expansive underground cavities at heights between 18 and 26 blocks, with the water level set at 22 blocks. Descending into the underground through mines or natural caves reveals grand stone halls beneath the player's feet, filled with subterranean seas.

The mod offers numerous configurable parameters allowing landscape adaptation to the maximum degree. If desired, you can configure underground spaces resembling the Nether's characteristic wastelands or create completely unique underground ecosystems of varying depth and scale.
