Demonstration 1

Orebfuscator - Anti X-RAY:

For all releases of 1.9/1.9.1/1.9.2/1.9.4/1.10: Version 4.1.1

Now with support for CraftBukkit 1.9/1.9.1/1.9.2/1.9.4/1.10!

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





Please read compatibility information before downloading as not all releases work with all versions of CraftBukkit.

Latest version should be on BukkitDev, or as a release on the Github page: https://github.com/lishid/Orebfuscator/releases

Please also download ProtocolLib and install it in the plugins folder.


  • 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.



  • Copy "orebfuscator-v4.1.1.jar" to your plugins folder
  • If you're upgrading from Orebfuscator.jar, move the contents of the "Orebfuscator3" folder to the "Orebfuscator4" folder

    @LordKainzo: Go

    Regarding your log error happened in two cases:


    [15:36:16] [Server thread/ERROR]: Could not pass event BlockPistonRetractEvent to Orebfuscator4 v4.0.14-SNAPSHOT java.lang.StackOverflowError

    [15:36:17] [Server thread/ERROR]: Could not pass event BlockPistonRetractEvent to dynmap v2.3-SNAPSHOT-1137 org.bukkit.event.EventException


    But "Stack overflow" exception (which is caused error in both cases) thrown by recursive calling of method in ChestShop:


    at com.Acrobot.ChestShop.Listeners.Block.Break.SignBreak.onBlockPistonRetract(SignBreak.java:88) [?:?]


    Therefore I could make assumption that this error is not caused by Orebfuscator or Dynmap but caused by ChestShop.

    Are you able to reproduce problem without Orebfuscator or ChestShop?

    I think without Orebfusactor exception will be thrown only inside Dynmap event handler, but without ChestShop it will not be thrown at all.

    Thanks for the eagerness! Definitely in the future just submit a pull request here: https://github.com/lishid/Orebfuscator/pulls as we'd love to integrate your contributions (especially if you've done the work already!) but in a fashion that won't cause confusion or concern.

    Oh ok I'm sorry, I updated it just for me but I saw a lot of people wanted it, so I shared it just for help while waiting for the true version. I'll remember this in the future, sorry again.

    @Nashoba04: Go

    Hey, please don't distribute jar files on this page.

    We have a github for a reason, if you'd like to get involved and help update the project, please contribute a fork on the main project.

    I know you probably aren't trying anything dodgy, but it's incredibly suspect when people distribute plugins in the MC community.

    (Or perhaps your account got compromised, etc. etc.)

    We should have an official update out shortly.
