About this project
What does Phosphor-Legacy add?
Phosphor-Legacy
Phosphor-Legacy is port of JellySquid's Phosphor mod to Legacy-Fabric.
Currently this is just the original 1.12.2 forge code changed in order to work with fabric.
Phosphor
Phosphor is a free and open-source Minecraft mod aiming to save your CPU cycles and improve performance by optimizing one of Minecraft's most inefficient areas: the lighting engine.
It works on both the client and server, and can be installed on servers without requiring clients to also have the mod.
Phosphor is designed to be as minimal as possible in the changes it makes, and as such, does not modify the light model or interfaces of vanilla Minecraft. Because of this, Phosphor should be compatible
with many Minecraft mods (so long as they do not make drastic changes to how the lighting engine works.) If you've ran into a compatibility problem, please open an issue!
