Large Biomes Dimension
by mahmudindev
Large Biomes Dimension adds a world type with a separate dimension in which biomes are much larger than in the overworld.
What it does
A world created with the large biomes world type gets its own dimension, so the larger biome layout stays apart from regular overworld terrain. A portal built with an obsidian frame and a grass block at the centre opens the way into it, and the frame has stone at the top corners and bottom corners, as the author describes it.
Biome mods that other players run are supported through a compatibility layer built on TerraBlender, including Biomes O Plenty and Regions Unexplored. The mod also handles passengers using portals and works alongside Create Addons and Portal Integration. Dimension Fixer and World Portal are required, and Fabric API is optional on Fabric. The mod is server-side only, so only the server needs it and players join without installing anything. It is for Fabric, Forge and NeoForge, with builds covering 1.20.1 – 26.3, and all rights are reserved, so the mod is not open source. Source code and an issue tracker are public.
