Gamma Utils

Welcome to the world of bright lighting! Gamma Utils is a client-side mod for Minecraft that fundamentally changes your perception of darkness in the game. With it, you can adjust the gamma level far beyond the standard brightness limitations.
Main Features
This simple yet powerful tool turns dark nights into bright days and caves into well-lit spaces. Essentially, it's a full implementation of Fullbright for Fabric.
Press G to toggle between 100% and 1500% gamma
Press H to toggle client-side Night Vision on or off
Night vision works better in combination with shaders than gamma adjustment
Complete Customization to Your Preferences
The mod offers numerous adjustments and functions. Here are some of the available capabilities:
