Extrabiomes
by WinEpicFin
Extrabiomes, a world generation addon, adds new overworld biomes with their own mobs, blocks and structures, from burnt forests to jellyfish-filled seas.
What it does
The biomes cover a broad set of terrain types. Frozen mountain variants follow where mesa plateaus were worn down by glacial erosion, a futuristic desert uses white concrete in place of sand, and a deep dark forest replaces a former forest with sculk. Jungle variants include a marsh inside jungles with tiny trees and shallow water, a jungle with gigantic stone pillars, a floating jungle that sits on the tallest peaks, and a fungal jungle that meets a mushroom island.
Mesa variants show up in several forms, including lush mesa and Bryce pillar biomes with small lakes. Extrabiomes requires Architectury API, Fabric API, Geckolib and TerraBlender, and Create and Create Fabric can be added as optional dependencies. Builds target the Fabric, Forge and NeoForge loaders. The mod runs on client and server, and it is open source under the GNU General Public License v3.0 or later.
