Mask
Buried protected ores are sent as natural host blocks like stone, deepslate, or netherrack.
Paper server ore protection
Oreveil server-side Minecraft ore obfuscation plugin
Oreveil keeps hidden ore data on the server. Players see believable stone until normal gameplay exposes the block, cutting off x-ray clients and weakening seed-based ore routes.
Move across the stone background to expose what the client never sees first.

Protection model
Hide value before it leaks
Oreveil does not detect every cheat. It removes the useful underground data from packets before modified clients can use it.
Reveal
Exposure rules reveal ore only when normal gameplay opens it through mining, caves, fluids, or block changes.
Resist seeds
Optional server-private salted distribution reduces the value of public seeds and ore prediction pipelines.
Operations
Strict packets, simple control
Tune protection without turning the server into a config archaeology project.
Transport
ProtocolLib packet rewriting is used where compatible. Oreveil falls back to synchronized chunk priming and block updates automatically.
Admin GUI
Use /oreveil for protected ores, exposure rules, host blocks, xray profiles, diagnostics, and managed worlds.
