Orebfuscator - Anti X-RAY:

Version: 3.0.5

This plugin is used to counter X-RAY Client mods.

It modifies data that are sent to clients to hide blocks of your choice, such as Ore, chests, dungeons, etc.

It does not manipulate blocks in the world file, thus is safe to use.

ProximityHider is a feature that hides chests that are far from players.


Configuration Guide





Dropbox link removed due to Bukkit regulations. Latest version should be on BukkitDev, if not, then the dropbox link is still in the forum thread.

Please also download ProtocolLib and install it in the plugins folder. Download link: http://dev.bukkit.org/server-mods/protocollib/


  • Advanced algorithm that hides ore, chest and and anything you specify in the configuration
  • Spout compatible, but optional
  • No modifications to CraftBukkit.jar is needed
  • Customize the blocks you want to hide
  • HIDES DUNGEONS and other blocks that are in the dark
  • Different hiding mode, or scrambling.
  • Extensive configuration. Change updating methods depending on your bandwidth and processing speed.
  • Hide hidden chests and furnaces until a player is close to it.


Install: Copy "Orebfuscator.jar" to your plugins folder, and restart/reload your server.

    Nope, that mod is useless against Orebfuscator.

    You need ProtocolLib plugin to work with Spigot.

    @iGamingStudioX: Go

    There used to be one, but then it got deprecated as you can disable stuff in the main plugin and get the same effect. For best performance go get Spigot, which has a built-in light version of Orebfuscator.

    to expose 2 layers, you can set InitialRadius to 2, but that will consume more CPU.

    Could you make the stripped down version available again? Many small server could use Orebfuscator to prevent X-rayers but they just can't afford all the speed and RAM. I suggest that you make one that can be chose from mode 1f and 2 and can set the height Orebfuscatoon occurs (Like below sea level) and what blocks will be Orebfuscated. I think the random blocks reappearing can be fixed by exposing blocks behind the first layer that is exposed to the player. I hope you can make the stripped down version with the core only for lightweight servers. Thanks!

    @siemaeniu500: Go

    It's a stripped down version with only the core obfuscation algorithm.

    Mode 2 doesn't take more CPU. maybe like 0.1% more than mode 1.

    @lishid: Go

    In spigot what version of orebufoscator is implemented? Light or full? And mode 2 in spigot will take a lot of cpu ?

    @Re4ly: Go

    The files didn't allow choosing "for 1.6.4" when I uploaded it because I updated so quickly before beta even came out.
