Frequently asked questions
How do I turn fullbright on and off?
Press the keybind (default is usually a configurable key) to toggle fullbright on and off instantly. You can rebind this key in your mod settings or controls menu.
Does fullbright work in the Nether and End?
Yes, fullbright works everywhere—caves, surface, Nether, End, and even underground. It gives you full vision regardless of the dimension or time of day.
Will fullbright affect other players on a multiplayer server?
No, fullbright only changes what you see on your client and does not alter any actual game data or rules, so other players won't see any difference.
Does fullbright break mob spawning or game mechanics?
No, fullbright is purely visual and does not change how mobs spawn, how light levels work for game logic, or any other mechanics—only what appears on your screen.
