Clearness
by AceOverDeuce
Clearness is a world-corruption survival mod in which an infection spreads through a world and permanently turns natural blocks into glass.
What it does
Once unleashed, the infection advances across the terrain in a relentless wave and erupts in new outbreaks within a few seconds, wherever it chooses. Players can track it with a seeker's compass, which points toward the anomaly at the start of a journey, while generated structures such as villages and temples are kept safe from the spread.
The mod changes the world itself, so it suits players who start a fresh world built for this experience and who accept that the changes cannot be undone. Backing up a world before installing it is advised, since the mod aggressively and permanently modifies the terrain. Clearness is published for Fabric and NeoForge across 12 release versions, 1.21.1 – 26.2, and it is released under the MIT License, though it is not open source. Installing it needs Fabric API on Fabric. Both the server and every player need the mod, because the environment is client and server.
