Ocean Revamp
by Thun
Ocean Revamp changes the ocean biomes of the world generator, so aquatic journeys across the sea take on new terrain and structures.
What it does
New ocean biomes replace the plain vanilla oceans with more varied water terrain. Players crossing the sea by boat or while exploring find different floors, depths and landmarks than the default generation provides, and a player can look for either of the two structures the mod places in these oceans.
The mod is a world generation addition that runs on the server. Installing it on a server is enough for new worlds to use the revamped oceans, and players connecting to that server need no additional installation. Fabric, Forge, NeoForge and Quilt builds are all published, together with a data pack option for server platforms, for 1.21.11 only.
The Fabric, Forge, NeoForge and Quilt files are all 0.0.1+mod for 1.21.11 in the beta channel, published on 2026-01-06. The code is released under the MIT License, but the project is not open source. Ocean Revamp has no required dependencies and works without other mods from the catalog.
Key features
New ocean biomes
Ocean biomes are rebuilt with new terrain, replacing the default oceans that vanilla world generation creates.
Two oceanic structures
Players can find either of two structures added to the ocean biomes, giving sea journeys fixed landmarks to reach.
Data pack option
A data pack build is available for server platforms that do not run mod loaders.
Server-side generation
New worlds on a server with the mod generate the revamped oceans, while clients do not need the mod to join.
