Orebfuscator - Anti X-RAY:

For all releases of 1.9/1.9.1/1.9.2/1.9.4/1.10/1.11/1.12.x/1.13.x: Version 4.4.3


Now with support for CraftBukkit 1.9/1.9.1/1.9.2/1.9.4/1.10/1.11/1.12.x/1.13.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.


As of 4.3.3, Proximity Hider has been enhanced to use line-of-sight checks, not just proximity! Upgrade today.

Final Notes
Good news! We've had some "at-scale" with over 100 people online simultaneously. I'm pleased to report that after fixing some performance issues in 4.1.10, Orebfuscator 4.1.14 until latest consumes less then 0.05% of tick time with 100+ players on a fairly modest server machine. You cannot beat that kind of performance, with this feature set, at that kind of load.
That said, if you run a larger server (100+ players), we'd be especially grateful if you could share your timings report with us.

A quick donation is always appreciated :D
