Orebfuscator - Anti X-RAY:

Version: 4.0.9

Now with support for CraftBukkit 1.9.x!

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





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-v4.0.9-SNAPSHOT.jar" to your plugins folder

  • Release 4.0.9 has significant improvements, please update right away and report any issues.


  • A command that generates the world cache for the existing chunks.


Version 4.0.9
  • Fixed crash when chunk section (16 x 16 x 16) has more than 127 different block types
  • Implemented different "transparent block" lists for Engine Mode 1 and Engine Mode 2. For now only difference is with lava block, for mode 1 it is non-transparent, for mode 2 it is transparent.
  • Implemented possibility to specify which blocks are transparent and not in the config file, sections: TransparentBlocks and NonTransparentBlocks.
  • Fix which may have solved java.util.ConcurrentModificationException
  • Fix for phantom blocks (visible after chunk reloaded) when player is digging straight line on the chunk border.
Version 4.0.7-beta
  • Corrected transparent block list. For example, lava blocks marked as transparent and therefore adjacent blocks are not obfuscating anymore
  • Improved performance of ProximityHider function
Version 4.0.5-alpha
  • Fixes teleport / join in the End causing client-side crashes.
  • Fixes failure to deobfuscate immediately on join.
Version 4.0.3-alpha
  • Updated to MC1.9.

Full release notes: In Github Release

Version 3.0.5
  • Updated to MC1.8.3.

    Anyone knowing a plugin to not avoid xray, but permit xray ? I'm using a custom ore generator and would like to see through rock in order to easily setup my generator config.

    I find plenty of xray-OFF plugins, but not a single xray-ON one.

    Hey, Sorry I thought you meant a reference to this plugin's code :[

    So anyway, build a spigot 1.9 using the buildtools.

    Then using Eclipse make a Project and modify the 'Build Path' to include the Spigot.jar as an 'External' Jar. As you normally would for any project.

    (You can't build the project without the spigot or craftbukkit jar anyways)

    You can inspect the elements from inside Eclipse.

    There is not likely to be a 'source of reference' for MC 1.9 for some time yet.

    @stonar96bukkit: Go

    If that is the case, it would be very hard for the 'Mods' to make x-ray modified clients

    Sorry, I think that's not possible in this way. Modifying the chunk packets would be very inefficient and hard to manage with the changes of 1.9 and there are also some things to initialize when the chunk sections and their data palettes (added in 1.9) are created which allows it to obfuscate blocks efficiently. I have already sent a PM to md_5 and asked him to add my code into Spigot 1.9. But as temporary solution PM me on Spigot.
