Boosted Brightness

Boosted Brightness

Boosted Brightness is a simple clientside mod that allows you to set your brightness beyond default levels to your liking. It makes use of Fabric (not Forge) and is compatible with Minecraft 1.19.

Check out the v2 changelog for details about new features! Mod Menu is optional but needed to view the custom brightness levels screen.



New Brightness Slider

The mod modifies the brightness slider in video settings, extending brightness range from 0% through 100% to -100% through 1200%.

200% to 500% gives a great balance between seeing differences in lighting and seeing well in the dark.

-50% to -100% is great for a more challenging caving experience.

1200% is full-bright.

Up to 5 Custom Brightness Levels

By default, there are 2 brightness levels: your existing brightness and 1200%. 
Add up to 3 additional brightness levels for every situation: caving, nighttime, full-bright, or super-dark.

Access these sliders using Mod Menu.

New Keybinds

Use keybinds to select particular brightness levels. If you press the keybind of the currently selected brightness level, the brightness is switched to the last used brightness level.

Use the raise/lower keybinds enable quick brightness changes in-game.

If you have two brightness levels, the "Select Next Brightness" works just like a toggle between the two brightnesses.
