oceans biomes

by tempis335

Oceans Biomes is a Fabric world generation mod that creates worlds made entirely of ocean biomes, with a configuration screen for choosing the ocean variants.

FabricClient and serverAll rights reserved1.19.4 – 1.21.8

What it does

The mod adds an Oceans Biomes world type to the world creation screen, selectable from the end of the world type list. Its configuration screen lets a player generate a world made only of oceans, a preset that removes land biomes altogether. Ocean variants can be picked from warm, lukewarm, cold, frozen and deep, and the depth of the ocean can be adjusted.

Islands can be enabled or disabled, and shipwrecks, ocean ruins, ocean monuments and ruined portals can each be toggled. Changes take effect on new worlds and on chunks generated after the change, so existing terrain keeps its current form. A server running it needs every connecting player to have it too. Files are published for Fabric only, for eight game versions: 1.19.4, 1.20.1, 1.20.4, 1.21, 1.21.1, 1.21.4, 1.21.6 and 1.21.8, with 1.2.2 for 1.21.8 as the latest file. The code is not open source, and the mod is released under All rights reserved.
