Fullbright — Horizon mod
Fullbright for Horizon: press G to toggle 1000% gamma in caves and at night, with a smooth 250 ms fade and a HUD notice.
Fullbright by CayMac is a one-key brightness switch. Press G and that cave or moonless forest is lit like midday; press it again and the dark comes back. Under the hood it pushes gamma to 1000%, fades over 250 ms instead of snapping, and shows a short HUD notice so you know which state you're in. Useful for cave mapping, night-time building without spamming torches, and filming underground builds.
Features
- G toggles maximum brightness (1000% gamma). The key can be rebound.
- A smooth 250 ms fade rather than a jarring flash.
- A HUD notice confirming on or off.
- Client-side only: it adjusts your lightmap and sends nothing to a server.
Compatibility and install
Native mod, version 1.0.0, for Minecraft 26.3, signed by its author. Install it on your instance's Mods page in the launcher and press Build in the "Native build of …" row. The first native build pulls down Rust and takes 20–30 minutes and a few GB of disk; rebuilds after that are a matter of minutes. Our mod install guide has the full steps.
Before you install
Horizon already ships a fullbright option in Options > Horizon Settings > Extras, off by default. If you don't care about a dedicated key or the fade, that may be all you need, and it saves you a native build. The mod's description is short: beyond the rebindable key, it lists no other settings. And fair warning from us: fullbright makes caves easier but also flattens the atmosphere, so you may want it on a key rather than always on.

How to install
Find the mod in the launcher
Open the Horizon launcher, pick an instance on the left and go to its Mods page. In the Horizon tab, find "Fullbright" and press Install.
Build the mods
In the Native build of … row press Build and confirm you trust these mods. The first build downloads Rust and takes 20–30 minutes and a few GB of disk; later builds take a couple of minutes.
Play
Play that instance — your other instances never run the mod. Turn it on and configure it in game under Options → Mods.
FAQ
How do I turn on fullbright in Horizon?
With this mod, press G (rebindable in Options > Mods > Fullbright). Horizon also has a built-in fullbright toggle in Horizon Settings > Extras, off by default.
Does the server see it?
It's client-side only: it changes your own lightmap and sends nothing to the server. That said, respect the rules of any server you join.
What does the mod add over the built-in option?
A dedicated toggle key, a 250 ms fade instead of an instant switch, and a HUD notice telling you which way it went.
How do I install Fullbright?
From the Horizon launcher: Mods page → find "Fullbright" → Install. The launcher checks the SHA-256 and the author's signature for you. A native mod is then compiled with the Build button — the first build takes 20–30 minutes. The full steps are in "How to install" above.
Which Minecraft version does Fullbright support?
The latest version, 1.0.0, targets Minecraft 26.3 on Horizon.
Can I download Fullbright from this site?
Yes. Its MIT license allows redistribution, so we host the file, and its SHA-256 matches the official registry.
