Orebfuscator - Anti X-RAY:

For all releases of 1.9/1.9.1/1.9.2/1.9.4/1.10: Version 4.1.4

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

  • HIDES DUNGEONS and other blocks that are in the dark
  • Different hiding mode, or scrambling.

    It is my great pleasure to be the first to beg Lishid for an update this time around. Bukkit builds are out at long last. :')

    Spigot comes with built-in Oreby, lel.

    @HF1n9i9c7om: Go

    Basically, it controls how many layers of block to leave alone that are close to exposure to air. If you have it set to 1, then anything that is directly touching an air block will not be obfuscated. If you have it set to 2, then anything touching an air block or is touching a block that touches air will be left alone (2 layers of blocks). However, most of the time, 1 is best. 2 is usually used to counter lag in some cases, and 3 is overkill and will probably lag your server.

    I'm a bit confused what exactly "InitialRadius" does... could you explain please?

    Doesn't work on Spigot 1.7.2 protocol.

    Sent Lishid an example exploit for orebuscator a few days back. Had not yet heard from them. Posting here as a tickle reminder. Would be fine posting example exploit code privately to Lishid if requested.
