Forever Frost

by Tobix

Forever Frost is a NeoForge world generation mod that transforms snow, ice and frozen landscapes across the whole world so they stop melting during the day.

NeoForgeClient and serverGNU General Public License v2.0 or laterOpen source1.21.1

What it does

Forever Frost changes the surface of biomes that already carry snow and ice. Snow, ice and the surrounding landscape across the world are converted, and ice in ocean areas stays in place instead of melting during daylight. The mod keeps the normal biome selection intact, so the world generator still places the same biomes as before.

The mod is compatible with other biome mods, including Terralith and snow-themed additions such as Snowrealmagic. It adds a Snow Grass Block and a Smooth Snow block for decorating frozen areas. Both the server and every player need the mod. Files are published for NeoForge 1.21.1 under the GNU General Public License v2.0 or later, and the source code is public. A planned update is noted by the author.
