Simple Fullbright
by MVPFishstock
Simple Fullbright is a Fabric client mod that brightens the whole world through a hotkey toggle, so caves and nights become readable without changing the game's gamma setting.
What it does
Pressing the G key switches fullbright on and off, and the hotkey can be changed to another key. While it is active, the lighting of the world is raised so that dark areas stay visible. The gamma value set in the options menu is preserved, so turning the mod off returns the screen to its previous brightness.
The mod is a small, single-purpose utility aimed at players who want to see in caves, nether fortresses or at night without carrying torches. It is also used in speedrunning, where a quick toggle helps keep navigation simple. Because it only changes how the client draws light, it does not alter the world, blocks or server behavior.
Simple Fullbright requires Fabric API and is published for Fabric only, for the single game version 1.16.1. Only the client needs it, so players join servers without installing anything. The code is under the MIT License, and the project is not open source in the sense of publishing a public repository with the mod's build history.
Key features
Hotkey toggle
A key binding turns the brightening effect on or off during play, defaulting to the G key.
Preserved gamma
The gamma setting in the options screen is left as the player configured it, so the toggle only affects the lighting.
Configurable key
The hotkey can be changed in the controls menu, so it does not clash with other bindings.
Speedrun-friendly switching
A single key press flips the lighting, which suits runs where players need to see dark areas quickly.
