Shhh Brightness Toggle

A simple, lightweight client-side brightness and fullbright mod for Minecraft 26.3 on Fabric.

Shhh Brightness Toggle lets you adjust world brightness with a hotkey or settings slider. Unlike older fullbright methods that apply a fake Night Vision effect (which spawns annoying potion swirl particles and clutters your HUD with a potion icon), this mod works directly with Minecraft's lightmap rendering. You get clear visibility in dark caves, ravines, and underwater without any potion clutter.

Features

• Toggle with a key: Press B (default) to turn fullbright on or off whenever you need it.
• Adjust brightness in steps: Use the Up and Down arrow keys (default) to change brightness between 10% and 100% in 10% steps.
• On-screen feedback: Shows your current brightness level when you change it. The message shifts from red at low brightness, to yellow at mid levels, to green at 100%. You can turn this off in the settings if you prefer plain text.
• No potion clutter: No potion swirls, no inventory status icons, and no screen flashing.
• Restores your normal brightness: When you turn the mod off, leave a world, disconnect from a server, or close the game, your original vanilla brightness setting is restored automatically.
• In-game config screen: If you have Mod Menu installed, you can open a settings screen with an on/off button, a slider, and a color toggle. Mod Menu is optional.
• Saves your preferences: Settings are saved in .minecraft/config/shhh-brightness-toggle.json. If the file is ever corrupted or empty, it resets to safe defaults without crashing.
• Client-side only: Runs entirely on your computer. It sends no network packets to servers and does not need to be installed on servers.

Default Controls

All three keys can be rebound in Options -> Controls -> Key Binds:

• Toggle Brightness: B
• Increase Brightness: Up Arrow
• Decrease Brightness: Down Arrow

Installation

1. Install Fabric Loader for Minecraft 26.3.
2. Put Fabric API into your .minecraft/mods folder.
3. Download shhh-brightness-toggle-1.0.0+mc26.3.jar and put it into .minecraft/mods.
4. (Optional) Install Mod Menu if you want to use the in-game settings screen.

Compatibility and Server Rules

• Sodium and Iris: The mod hooks into lightmap rendering at the end of the method rather than replacing it. It is designed to work with Sodium and Iris, but has not been tested with every possible mod combination. Please report any issues on GitHub.
• Server Rules: Some multiplayer servers do not allow fullbright mods. Check the server rules before using this mod online. Use at your own risk.

Updating Between Versions

This mod hooks into Minecraft's internal lightmap extractor (LightmapRenderStateExtractor). In future Minecraft updates, Mojang may change how internal lighting works. Each new Minecraft version requires testing, and a new mod version will be published if necessary.
