Customizable Brightness - Fullbright & Gamma Control

Customizable Brightness

✨ Now with shader support! (Minecraft 26.1+ with Iris)

Fullbright with control. Press one key to step through brightness levels, from complete darkness to full cave vision, and the game remembers where you left it. On Minecraft 26.1 and newer, it works with shader packs too.

Press B in game to change brightness. Each press moves to the next level: 0% → 100% → 200% → 500% → 1000% by default. The current level appears above your hotbar.

Why this mod

Most fullbright mods are a single on/off switch. That works until you want full visibility while mining, then normal lighting back at your base where you spent hours getting the torches right. Or a darker night for a horror map. And most of them stop working the moment you turn on a shader pack, because shaders ignore Minecraft's brightness above 100%.

Customizable Brightness gives you a set of levels you choose yourself and one key to move between them. Bright for the caves, normal for the base, dark for the atmosphere, and on 26.1+ it keeps working with shaders. It starts where you left it, it doesn't fight your settings, and it stays out of the way.

Features

• Levels, not a toggle. Step through as many brightness stops as you like with a single key.
• Your own stops. Defaults are 0%, 100%, 200%, 500% and 1000%. Change them to anything from 0% to 10000%.
• Shader support on 26.1+. With Iris, levels above 100% raise the shader pack's own lighting instead of putting a filter over the image. Full brightness at 1000%.
• Remembers your level. The game reopens at the brightness you left it on, including with Sodium.
• Clear feedback. The current percentage shows above your hotbar each time you press the key.
• Easy to find. New players see a small hint in the corner with their key until they first press it.
• Works with the vanilla slider. The B key and Minecraft's Brightness slider share one level, so they never disagree.
• Client-side only. Nothing to install on servers, and it never touches your worlds.

Shader support

On Minecraft 26.1 and newer with Iris, every level works. Above 100%, the mod brightens the scene through the shader pack's own lighting, so the pack still looks like itself, just with more light.

• Tested with Complementary Reimagined and Complementary Unbound.
• Most packs respond the same way. A few, like Sildur's Vibrant, only show one bright level above 100%, and packs that ignore Minecraft's lighting entirely won't get brighter.
• On older versions, 0% to 100% works with shaders, and higher levels look the same as 100%. Without shaders, every level works on every version.
• Still being tested, feedback is needed on this

Installation

1. Install Fabric Loader and Fabric API.
2. Download the file for your Minecraft version and place it in your mods folder.
3. Launch the game and press B.

Optional: install Mod Menu and Cloth Config to edit your levels in game (1.16.5 and newer).

Configuration

In game: Mods → Customizable Brightness → config button.

By file: config/customizable_brightness.properties

# 1.0 = 100%
brightness_stops=0.0,1.0,2.0,5.0,10.0

Keybind: Options → Controls → Key Binds → Customizable Brightness.

Compatibility

• Sodium: fully supported.
• Iris: supported; see Shader support above.
• Mod Menu / Cloth Config: optional, for in-game configuration.

Every release is launched and tested in the actual game on every supported Minecraft version before it's published, including restart persistence and runs with Sodium and shader packs.

FAQ

Is this allowed on servers? The mod is client-side only, but high brightness can be an advantage. Check your server's rules.

Why does 100% look different from vanilla "Bright"? It doesn't. 100% is vanilla's maximum. Everything above it is the mod.

Can I set more than five levels? Yes. Add as many values as you like to brightness_stops.

I pressed B and nothing happened. Check Options → Controls → Key Binds. If the key shows in red, another mod is using B. Rebind one of them.

Customizable Brightness – Fullbright & Gamma Control

Press B in game to change brightness. Each press steps to the next level (0% → 100% → 200% → 500% → 1000% by default), and the current level shows above your hotbar. Change the key under Options → Controls → Key Binds → Customizable Brightness.

Tired of fullbright mods that are only "on" or "off"? Customizable Brightness lets you cycle through as many brightness levels as you want with a single key, from pitch black (0%) to ultra-bright cave vision (1000%+).

✨ Features

• One key, many levels: press B to step through your brightness stops
• Your own stops: defaults are 0%, 100%, 200%, 500% and 1000%, fully customizable
• Remembered between sessions: the game reopens at the level you left it on
• Instant feedback: the current percentage appears above your hotbar on every press
• Easy to discover: a small hint in the corner shows your key until you first press it
• Beyond vanilla limits: goes far past Minecraft's 100% brightness cap
• Complete darkness mode: 0% for atmospheric or horror gameplay
• In-game config: via Mod Menu + Cloth Config (1.16.5 and newer)
• Client-side only: nothing to install on servers
• Huge version support: 44 Minecraft versions, from 1.14.4 to 26.3

🎮 Perfect For

• Cave exploration without placing torches
• Mining in deep dark areas with full visibility
• Ancient city exploration
• Night building and mining without potions
• Horror maps and atmospheric playthroughs at 0%

📦 Installation

1. Install Fabric Loader and Fabric API
2. Download the file for your Minecraft version and put it in your mods folder
3. Launch the game and press B

Optional (in-game config, 1.16.5+): Mod Menu and Cloth Config

🎯 Supported Versions

⚙️ Configuration

• In game: Mods → Customizable Brightness → config button (needs Mod Menu + Cloth Config)
• File: config/customizable_brightness.properties, for example brightness_stops=0.0,1.0,2.0,5.0,10.0 (1.0 = 100%)
• Keybind: Options → Controls → Key Binds

⚠️ Known Limitations

• Shader packs (Iris / OptiFine shaders): most shader packs do their own lighting and ignore brightness above 100%. With shaders on, 0% to 100% works, but higher levels look the same as 100%. Without shaders, every level works, including with Sodium.
• The B key and the vanilla Brightness slider share one level. Moving the slider sets brightness (0–100%) and is remembered; pressing B afterwards steps to the next level above it.

❓ FAQ

Why not just use another fullbright mod? Most are simple on/off toggles. This gives you as many levels as you want, remembered between sessions.

Is this allowed on servers? It's client-side only, but extreme brightness can be an advantage, so check your server's rules.

Can I set custom levels? Yes, any value from 0% to 10000%, in the config file or the in-game config.
