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.

    @Jones988: Go

    I had a player say that he found ores that disappeared when he started mining it. Would this be an issue related to Orebfuscator?

    Yes this could be related to Orebfuscator, but I need more details. Do you have any steps of how to reproduce problem?

    Maybe if the server crashes, some of the fake ores don't disappear?

    Depending on how server crashed, so I cannot exclude this possibility. You can run /ofc clearcache to clear cache, but during players activity cache will be renewed so earlier or later it will be correct even without clearcache command.

    @TeenWolf23: Go

    Regarding to log you are using spigot 1.8, but Orebfuscator 4.1.2 is supporting only versions of MC 1.9 - 1.10.2

    I suggest you to look here for old Orebfuscator: https://github.com/lishid/Orebfuscator/releases?after=v4.0.7-alpha

    Also possibly you need to get older version of ProtocolLib since I'm not sure if latest version is supporting 1.8 spigot

    @alekseymc: Go


    That is for the most part the log if you want more let me know. I did a reload to get this just to make it easier if you want a log from a server restart i can give you that to.

    Orebfuscator isn't working, it says "28.07 04:54:04 [Server] ERROR Error occurred while enabling Orebfuscator4 v4.1.2 (Is it up to date?)" and then when i check the status in game it says "ProtocolLib not found" but ProtocolLib is working on the server so I'm not exactly sure what i did wrong lol but anyone have suggestions?
