Kyo's Cottonwood Forest
by ThatNerd123
Kyo's Cottonwood Forest, a NeoForge mod for 1.21.1, adds a cottonwood biome, a cottonwood wood type, and an allergy system tied to walking through that forest.
What it does
Cottonwood forest is a new biome added by the mod. Its trees use a cottonwood wood type, so the planks, logs and related blocks made from it appear as a separate set of building materials. Walking through the cottonwood forest triggers an allergy system, which is the mod's main mechanic and gives the biome its distinct gameplay.
String can be crafted in a new way: nine lumps of cotton produce three string. This gives players a route to string from cotton without relying on another source. Installation covers the server and each player's game. Files are published for NeoForge only, for 1.21.1, and the mod is released under All rights reserved, so it is not open source.
