Demonstration 1

Orebfuscator - Anti X-RAY:

For all releases of 1.9/1.9.1/1.9.2/1.9.4: Version 4.0.14

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

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

  • 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.

    @spiderrecon11b: Go

    Few questions:

    1) Did you install ProtocolLib 4.0?

    2) Do you have any errors in the server's log?

    I shutdown my server and put the jar file in, Ithen restarted my server and when the config file was created i shut it down again and put your config setting into the folder then restarted the server and it is still not working. I dont know if it makes a difference or not but my server is bukkit not Spigot just something that might cause and issue, idk

    @austin652: Go

    How to reproduce problem?

    Could you please post issue with all details?(versions, config, steps and etc)

    Are you sure this is orebfuscator's problem? Did you try this without orebfuscator?

    Is there a way to disable item drops appearing as stone?, for example if I dropped a diamond on the ground it doesn't show a diamond, it shows as stone.

    Woah, he provided a plugin for FREE that you get to use on your server. There is no need to treat anyone like this. Especially when you didn't even update your damn plugin to the one that was posted 5 days ago before going nuts. This is not tolerated on this site and next time you will be removed.

    Thanks, Zeldo

    @MrJordan9821: Go

    According to the timings you pasted, you are using 4.0.12 - which does not support 1.9.4.

    Please update to, instead. A link, for convenience: http://dev.bukkit.org/bukkit-plugins/orebfuscator/files/152-orebfuscator-4-0-12-1-1-9-4/

    @Renzotoms: Go

    and others - 1.9.4 compatible build posted.

    This build is NOT backwards compatible. If you're still running 1.9.2 or earlier, do not update - but for everyone on 1.9.4, please, use this release.

    @BoomerBR: Go

    In my testing I used:

    • CraftBukkit version git-Spigot-db6de12-07c3001 (MC: 1.8.8) (Implementing API version 1.8.8-R0.1-SNAPSHOT)
    • Orebfuscator version 3.0.6-R3
    • Protocollib version 3.6.5

    Orebfuscator Config: http://pastebin.com/0jwVh1qX

    Note - I manually disabled Spigot's built in anti-X-ray in spigot.yml : world-settings.anti-xray.enabled: false

    Without Orebfuscator: http://i.imgur.com/zK8iSk2.png

    With Orebfuscator: http://i.imgur.com/O0LJeKP.png

    This worked well in my testing, and also applies darkness hiding.
