Just Brightness

A lightweight client-side brightness toggle for Minecraft 26.3 on NeoForge.

Make dark places easier to see

Just Brightness lets you enable or disable an enhanced gamma value with one key press. Use it while exploring caves, building at night, or whenever you want a brighter view, then switch back to your normal vanilla brightness just as quickly.

The mod changes the gamma value used by the client renderer. It never writes to Minecraft's saved brightness setting, so disabling it restores your own vanilla brightness setting.

Features

• Press B by default to toggle enhanced brightness
• Set the gamma used while enabled, from 1.0 to 32.0
• Enhanced brightness and the toggle message are enabled by default
• Choose whether enhanced brightness starts automatically when entering a world
• Show or hide the temporary action-bar message after a toggle
• Rebind the toggle key in the standard Options → Controls screen
• Bind a separate Open Settings key to configure the mod in game
• Client-side only, with no runtime dependencies beyond NeoForge

Settings are stored in config/justbrightness.toml.

Installation

1. Install NeoForge for Minecraft 26.3.
2. Download the NeoForge 26.3 JAR.
3. Put the JAR in your Minecraft instance's mods folder.
4. Launch the game.

Use on servers

Just Brightness is installed on the client only and does not need to be installed on a server. Brightness-related client modifications may be restricted by a server's rules. Check those rules before using it in multiplayer.

Compatibility

Just Brightness changes only the client renderer's gamma value. It does not modify worlds or send data to external services. Shader packs can control lighting independently, so the visible result may vary with the shader pack.
