Orebfuscator - Anti X-RAY:

Version: 3.0.4

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





Dropbox link removed due to Bukkit regulations. Latest version should be on BukkitDev, if not, then the dropbox link is still in the forum thread.

Please also download ProtocolLib and install it in the plugins folder. Download link: http://dev.bukkit.org/server-mods/protocollib/


  • 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.


Install: Copy "Orebfuscator.jar" to your plugins folder, and restart/reload your server.

    So i'm using the last version (3.0.4) of Orebfuscator, but on a 1.7.10 server instead of a 1.8.1. Should i use the 2.1.7 version for CB 1.7.9-R0.2?

    Do i have a problem because some of the mods i'm using are declaring new blocks unknown to Orebfuscator? (i use the Lord of the Rings mod, and More Player Models mod)

    Is it a side issue with the Spiggot included in my Cauldron server, as i see that it seems to include an anti xray feature? (currently disabled in my case: anti-xray: enabled: false)

    And, finally, is there a simple way of knowing if it works?

    Thanks in advance for your help!

    Best regards,

    Works fine on my server, no laggs.

    Is there a permission so I can still X-Ray myself ?

    Like a permission to not send the packages to a person ?

    @MarioG1: Go

    Thank you for your advice, but in my case it did not change anything. It seems that there was not much to do to regain the fluidity before the 1.8 :/ If I reduced the list "RandomBlocks:" could it improve something?

    Hey,i have so much lags with this plugin (1.8) and i want to change the blocks to air i diable AntiTexturePackAndFreeCam and i changed the random block to 100 and its still not work

    @lishid: Go

    I know that AntiTexturePackAndFreecam has nothing to do with block ID's. But if you disable AntiTexturePackAndFreecam you still have air blocks under ground with the default settings. If you remove 129 (Emerald Ore) the air blocks are gone. I also tried this with other blocks with ID's > 100.

    @Bobcat00: Go

    I did some testing with AntiTexturePackAndFreecam and vanilla mc on my PC:

    AntiTexturePackAndFreecam ON and default Random blocks 490 FPS AntiTexturePackAndFreecam ON and Random blocks with ID's < 100 540 FPS AntiTexturePackAndFreecam OFF 622 FPS

    On an strong PC you won't notice any difference but people with slow pc might get problems.

    @MarioG1: Go

    That's not the case.

    Disabling AntiTexturePackAndFreecam basically means no random air blocks are generated. This has nothing to do with block IDs, other than sending some of the blocks (randomly selecting some) to being an air block instead of whatever the random block generator would.

    @MarioG1: Go

    I thought the random air blocks caused FPS lag only for people running hacked clients. In other words, people running legit Minecraft won't have additional FPS lag from this plugin.

    @Chevels: Go

    The FPS lag is caused by random blocks with an id > 100 because they are send as air to the client.

    Disable AntiTexturePackAndFreecam and remove all blocks with an id > 100 from teh random blocks list, reload ofc and clear the cache. The lag should be gone.
