XRay and Fullbright Mods for Minecraft (2026 Guide)
XRay mods let you see through blocks to find ores, caves, and structures. Fullbright removes darkness so you see everything without torches. Both are popular utility mods with important caveats about server rules.
XRay Mods
What XRay Does
XRay makes most blocks invisible or transparent, leaving only valuable blocks visible: diamonds, iron, gold, emeralds, ancient debris, chests, and spawners. Some versions also highlight caves and lava pools.
Popular XRay Mods on Modrinth
- Advanced XRay (Fabric/Forge) - Configurable block list, keybind toggle
- XRay Mod - Simple toggle with customizable ore highlighting
How to Install
- Download for your mod loader (Fabric or Forge)
- Place the jar in
.minecraft/mods/ - In-game, press the XRay keybind (default varies by mod)
- Configure which blocks to highlight in the mod settings
Fullbright Mods
What Fullbright Does
Fullbright sets the brightness to maximum everywhere. No dark areas. No need for torches to see. Caves, the Nether, and nighttime are all fully lit on your screen.
Options for Fullbright
- Gamma Utils (Fabric) - Adjusts gamma beyond the vanilla slider
- Fullbright Toggle (Fabric) - Simple on/off keybind
- Vanilla trick: Some versions let you edit

Server Rules
This is important. Most multiplayer servers ban XRay mods. They give an unfair advantage in survival and PvP by letting you find resources faster than other players.
Allowed on most servers:
- Fullbright (cosmetic, does not reveal hidden blocks)
- Minimaps without cave mode
Banned on most servers:
- XRay (reveals ores and structures)
- Cave finders
- Entity ESP (shows player positions through walls)
Anti-XRay on Servers
Server owners use anti-XRay plugins to counter these mods:
- Paper's built-in anti-xray sends fake ore data to clients
- Orebfuscator replaces hidden ore textures with stone on the network level
With proper anti-XRay enabled, XRay mods show only fake ores. The real ores are hidden until you physically mine next to them.
Singleplayer Use
In singleplayer, there are no rules. Use whatever mods you want. XRay is useful for:
- Finding strongholds and mineshafts
- Locating specific ores quickly
- Exploring cave systems
- Creative mode planning
The Bottom Line
Fullbright is generally accepted everywhere. XRay is singleplayer-only on most servers. Always check server rules before using utility mods. Server owners should enable Paper's anti-XRay to protect their survival experience.
