Description

Gamma Utils

This is a fully configurable and client side Gamma / Brightness utility mod, making it much easier to see in the dark.
It's a really basic mod that allows you to change the gamma value in game way higher than the in game brightness setting allows.
Nights will look like day and caves will look like they're fully lit up. Basically Fullbright / Gammabright but for Fabric and NeoForge.

Press G to toggle between 100% and 1500% Gamma

Press H to toggle client side Night Vision on or off
This works better in combination with shaders than gamma

Fully adjustable to your liking

To see everything that can be done and adjusted open the function and configuration spoilers below.
Here are some examples of what's possible though:
