This plugin is used to counter X-RAY client mods, texture packs, chest radar, and other similar exploits 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.
