Pocket Mansion

Crafting the Pocket Dimension item is the step that opens the mod. Its recipe uses obsidian, gold ingots and a diamond, so it sits behind a mid-game gate: obsidian has to come from the Nether and a diamond must be found first. Using the item sends the player into a world that belongs to them alone, and the mod records the coordinates of the place they left, so returning to the overworld puts them back where they came from.

Mob Capsules handle animals. A capsule can take a peaceful tamed animal along into the private dimension, while hostile mobs and players cannot be captured. Captured animals are released only inside the pocket world, which keeps them away from other players' worlds. Hostile mobs in the overworld do not follow, so the private world is free of the time pressure that applies elsewhere. Copper and gold ingots form the early capsule recipes, so a player can start collecting animals before reaching the diamond stage.

The mod is built for NeoForge and works on client and server, so the server and every player need it. Files exist for NeoForge 26.1.2 only, with 0.1.0 as the latest, published 2026-05-16. The code is released under the MIT License, but Pocket Mansion is not open source.
