Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

FTB Team Bases

Overview

FTB Team Bases is a replacement in MC 1.21.1 for earlier base management mods, including FTB Team Dimensions, FTB Team Islands and FTB Dungeons. It will ultimately include functionality from all of those. Planned functionality includes:

Creating bases in a static shared dimension (like FTB Team Islands; dimension ID is ftbteambases:bases by default)
Creating bases in a private per-team dimension (like FTB Team Dimensions)
Creating bases from pregenerated region files, using off-thread copying and relocating of template MCA files into the target dimension (suitable for huge bases, spanning 1 or more entire 512x512-block regions).
- Note: this is only suitable for void dimensions, or non-void dimensions with a fixed seed, so the pregenerated regions fit properly with existing worldgen.
Creating bases by putting down a Jigsaw block and running jigsaw generation over several ticks (like FTB Dungeons - suitable for large dynamically generated bases)
Creating bases by pasting a single NBT structure (suitable for small bases)

The mod is driven by base definition files, which are JSON files in a custom datapack (<mod-id>/ftb_base_definitions/*.json). Each definition file is a template from which a live team base is created. Every live team base has a 1:1 association with an FTB Teams team; when FTB Team Bases is loaded, teams can only be created by creating a base, and when a team is disbanded, players will be ejected from that base, and the base archived.

Four default base definition files are shipped with the mod, although none of these will be displayed as GUI options when creating a base, unless you're running the mod in a development instance (from an IDE), or you've set show_dev_mode to true in the client config.
