Biospheres Renewed

Players wake in a sprawling landscape inside a glass dome suspended over an endless void. A narrow wooden bridge carries them from one dome to the next, and each crossing leads into a separate world with its own terrain and biomes. Most third-party biomes generate inside their own dedicated sphere, so custom biome packs can be explored without mixing into the others.

The environment is server required and client optional: the server must run the mod to generate the domes, while players may join without it, although the mod's content is only visible when a client has it installed. The mod is published for Fabric, Forge and NeoForge, with files for 1.20 – 26.1.2, and the code is licensed under the GNU General Public License v3.0 or later, so it is open source. Biospheres Renewed is compatible with a broad range of other mods, and the author notes that custom biomes such as those from Autumn Woods and Magical Forests are a planned focus.

The mod is a maintained continuation of the original Biospheres concept by Risugami, and the project lead overhaul is by MrLogiousBanana, with contributions from FarlanderCraft, Coolsa, zraffleticket and earlier maintainers. The author notes that the code was developed as a pair-programming effort with an AI assistant.
