FTB Team Bases

Source-provided project description. FreeMinecraftMods keeps creator credit and adds separate compatibility and decision guidance below.

Project overview

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.

FreeMinecraftMods decision guide

This mod is most relevant to players looking for Miscellaneous on NeoForge, Forge, Fabric. Treat those labels as discovery hints, then verify the exact file and dependency list on the official project page.

The source record was updated on Jul 24, 2026, which is a recent freshness signal. A recent date does not guarantee support for every loader or Minecraft version, so still inspect the current file list.

What to verify before choosing a file

• Confirm that the file is published by the credited creator on the linked official source.
• Match the Minecraft version exactly instead of relying only on a broad category label.
• Read dependencies, incompatibilities, and changelog notes before updating an existing instance.
• Match the loader or server platform and its required version. Forge and NeoForge are not interchangeable.
• Back up worlds and configuration files before testing the project in a long-term save or public server.
