Orebfuscator - Anti X-RAY:

Version: 4.0.7-beta

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-v4.0.7-SNAPSHOT.jar" to your plugins folder
  • If you're upgrading from Orebfuscator.jar, move the contents of the "Orebfuscator3" folder to the "Orebfuscator4" folder

    Ah ha - invisible trees. That explains it!! I saw some snow floating in the air, and I couldn't move around underneath it. I kept bumping into something. Now I know it was an invisible tree.

    I also saw something else which may be related. When exploring, I see that snow, grass, and trees are placed in 8 block wide "stripes". 8 blocks of snow (or whatever) then 8 blocks of empty ground. If I leave the area and come back, the whole landscape is populated correctly. I wonder if this could be related to the invisible trees.

    Hey lishid, Still getting a lot of trees cut in half and other invisible buildings/terrain. this is fixed upon rejoining the server. Let me know when you get the time to address this, thanks!

    Thank you for the quick updates.

    In 2.0.3 the users are complaining of 'invisible trees'. They say they can often not see trees at all and end up stuck inside of them when they accidentally run in to them. Sometimes they only see parts of trees.

    No errors on the console when this occurs.

    EDIT: I cleared the cache to be sure, it didn't help.

    @Almantsas: Go

    I would redirect you to ProtocolLib as the error seems to be from ProtocolLib. I'll give the author a message too.

    Thanks for fixing the disconnects so quickly. I had just opened my 1.7.2 map and the initial players were getting pretty frustrated.

    Orebfuscator 2.0.3 is released for a small fix caused by concurrency.

    Early access [Mod edit: Is not allowed.]

    @Almantsas: Go

    Thanks. Fixed in version 2.0.3.
