Customizable Brightness – Fullbright & Gamma Contro

by SimplyAG

Customizable Brightness – Fullbright & Gamma Contro is a Fabric client mod that cycles the game's brightness through configurable levels with one keybind.

FabricClient-side onlyMIT LicenseOpen source1.14.3 – 26.2

What it does

Pressing B switches the brightness between preset levels, by default 0%, 100%, 200%, 500% and 1000%, and the current percentage is shown on the action bar. The stops can be added, removed or changed to suit a playstyle, and values can go far past the vanilla gamma cap, up to 10000% when set in the config file. Setting a stop to 0% gives a complete darkness mode for horror or atmospheric play.

The chosen brightness is saved and restored between game sessions. Optional in-game editing uses Mod Menu with Cloth Config API, which adds a GUI for the stops from version 1.16.2 on. The mod also works alongside shaders, and the source code and issue tracker are public.

The client alone runs it, so no server installation is needed, but server owners should check the server's rules because brighter visibility may be treated as an unfair advantage. Fabric API is required, and the mod is released under the MIT License and is open source.

Key features

  1. Multiple brightness stops

    Five default stops can be edited, so the set of levels can match how a player explores caves or the surface.

  2. One-key cycling

    A configurable key moves to the next stop immediately, with no menu to open.

  3. Persistent settings

    The selected level and the stop list are kept between sessions, so the setup is not lost on restart.

  4. Beyond vanilla limits

    Stops can exceed Minecraft's 100% gamma ceiling, giving far more visibility in deep caves.

Use cases

Cave exploration

A player can raise brightness in underground areas and drop it back to vanilla levels on the surface.

Horror play

A 0% stop allows a complete darkness mode for players who want a tense, dark setting.

Who it’s for: Players who want finer control over brightness than a simple on or off fullbright toggle gives, and who play on single-player worlds or on servers that allow client-side brightness changes.

Questions

Does Customizable Brightness need Fabric API?

Yes. Fabric API is required and must be installed next to the mod on the Fabric loader.

Is Customizable Brightness needed on a server?

No. Players add it to their own game, and a server needs no copy. Server owners should still check the server's rules before allowing it.

Can the brightness stops be edited without the config file?

Yes, with Mod Menu and Cloth Config API installed, the stops can be edited through a GUI from version 1.16.2 on.
