How do I install Gammabright?

First install Forge or LiteLoader for your Minecraft version. Download the mod file matching your version, then place it in your .minecraft/mods folder. Restart the game and it will load automatically.

What's the default keybind to toggle Gammabright?

Press G to toggle the mod on or off. You can change this in the Minecraft Controls menu just like any other keybinding. Max brightness starts at 1500%.

Can I use Gammabright with other mods?

Yes, Gammabright is designed to work alongside other mods. Since it only modifies the brightness system, it rarely conflicts with anything. Just make sure you're using compatible versions of Forge or LiteLoader.

Does Gammabright work on multiplayer servers?

Gammabright is a client-side mod, so it works on any server. It only affects your local brightness view and won't cause server conflicts or kicks.

What's the difference between normal arrow key brightness and sneak mode?

Holding the arrow keys normally changes brightness by 10% per tick. If you sneak at the same time, the change jumps to 20% per tick for faster adjustments. Both modes work with the same keys.
