Cozy Cauldron

Want to take your base on the move? Finding airships too high-tech, TARDISes too vast, and pocket dimensions too empty? Looking for something a bit more mystical, a bit… cozier?

Simply drop an ender pearl into a cauldron full of water to transform it into a Manifold Cauldron. Then sneak while standing on top of it to enter your new home between worlds!

Free from mobs, weather, and other Overworld annoyances.
Respects the Overworld's day/night cycle, so don't be afraid to bring your bed in here.
Can be broken and placed wherever you want, in whatever dimension you want. (Nested cauldrons are technically possible!)

Technical Details

Each new cauldron's interior space occupies the center of a 512 by 512 block grid cell in the cauldron dimension. New interiors are generated in a spiral pattern around the origin.
Picking the block of a placed cauldron in Creative mode creates a cauldron linked to the same internal space.
Lost or disconnected cauldron interiors can be reconnected using /cozycauldron reassign <index>, where <index> is the order in which an interior was generated. /cozycauldron list lists all generated spaces and their indices.

Known Issues

Beds placed in the cauldron dimension don't register interactions.
Cauldron items forcibly assigned to existing interiors with commands don't get the appropriate enchantment glow effect, and may spawn the player in strange places within the cauldron when entering.
Rarely, players entering a cauldron can be spawned stuck inside the ceiling and walls of the entrance.
Jade may display a missing model when looking at the cauldron's exit blocks.
Using Iris shaders causes the portal shaders on the cauldron and exit blocks to stop rendering.

Future Plans

Freeform terrain manipulation of the cauldron's interior, with the ability to create organic rooms and passages and reshape them in real-time
Bedrock walls to separate grid cells?
