Speedy's More Biomes
Speedy's More Biomes adds new overworld biomes to NeoForge 1.21.8, including a salt flat, volcanic falls, a redwood forest, a hemlock forest, a chestnut forest and icy caves.
What it does
Each added biome has its own surface blocks and tree types, so terrain changes as a player travels. The salt flat uses salt blocks as its top layer, while volcanic falls use volcanic sand over volcanic stone. The redwood forest is filled with giant red trees, the hemlock forest with hemlock fir trees, and the chestnut forest with chestnut, hornbeam and hazel trees. A clear open biome with small grass scattered across it is also included, and the ice caves hold an icy floor over icy stone.
The mod is for NeoForge only and has a single build, version 1.0, for 1.21.8, published on 2026-01-01. Both the server and every player need it, because it generates world content on the server and the client must match. The code is All rights reserved, so the mod is not open source.
