Use Fullbright on Multiplayer Servers
How it works on servers
Fullbright is completely client-side, meaning it only affects what you see on your screen. Other players cannot see that you have it enabled, and it doesn't send any special data to the server. You can use it on any multiplayer server without triggering anti-cheat systems or breaking server rules.
Enable it like normal
Press B to toggle Fullbright on whenever you're playing on a server. The brightness effect works exactly the same way as it does in single-player worlds. You'll see perfectly in dark caves and at night while other players might still need torches.
No performance impact on others
Since the mod only modifies your client-side rendering, it won't cause lag for you or anyone else on the server. Your game runs smoothly regardless of how many players are online.
Play fairly
While Fullbright is allowed on most servers, always check your server's rules first. Some servers may have specific policies about visual mods.
