Oceanus

Oceanus makes your world smaller without the need for an intrusive world border. This is done by preventing land generation once you've travelled a certain distance, creating a circular world surrounded by endless ocean.

Version 2.0.0 now requires More Density Functions mod, and is no longer compatible with jacobsjo's datapack map

Configurability (datapack only)

All configurable values can be accessed in the directory data/oceanus/worldgen/density_function/configurable.

• Unaffected Radius: Radius around spawn where terrain generation is unchanged from vanilla
• Falloff Radius: Width of the band in which land is gradually overtaken by the ocean
• Mushroom islands: Enable or disable mushroom island generation in the endless ocean
• Offset: Offset the center of the unaffected/falloff area
• Ocean Variability: How varied the ocean terrain is, from endless deep ocean to regular ocean generation

Compatibility

In general any mods or packs that don't drastically alter worldgen should be compatible with Oceanus, including most popular biome mods. An easy way to verify this for datapacks is by using the Datapack Map by jacobsjo.

Please note that version 2.0.0 is no longer compatible with the datapack map. to check compatibility, you can still use the older versions to check compatibility with other pack by donwloading them and adding to the datapack map with "open Pack or Mod", tho i strongly recommend actually playing with 2.0.0+ for better performance.

If Oceanus doesn't seem to be working, try changing the load order of the pack, it should generally be at the bottom of the list.

FAQ

Does this work with large biomes?

Yes

Does this work with pre-existing worlds?

Yes! Generation in the unaffected radius is, well, unaffected. So as long as you haven't travelled beyond that (or are willing to regenerate those chunks), you should be able to use Oceanus on any existing world without creating ugly chunk borders. Still, always make backups.

Will you port the pack to versions before 1.19?

Datapacks couldn't really change worldgen before that. Others are free to take this idea and make it a mod for those versions.
