Compatibility Note: Ghosting/Free-cam Seeing Fake Ores is NOT a Bug

If players see "fake ores" while using "Free-cam" or "Spectator-like" mods/abilities, this is generally not a bug.

Reason: These "Soul/Free-cam" forms typically do not send valid movement or interaction packets to the server like a normal player entity. Consequently, the server does not trigger the standard chunk visibility refresh or "de-obfuscation" workflow. The Anti-Xray system continues to return obfuscated results according to its rules.

Simplified Explanation:

• Normal Player Behavior: Triggers server updates -> Fake ores are de-obfuscated (revealed) as per mechanism.
• Free-cam Perspective: Often fails to trigger server updates -> Obfuscated results remain visible.

Paper Anti-Xray Porting Progress

As of 2026-04-02, the current development status is as follows:

• Engine 2 Core Behavior Alignment: ~98%
• Paper Anti-Xray Full Source/Config System Alignment: ~98%
• Complex Cave Environment Loop Readiness: ~97%

Key Completed Capabilities:

• Full interception of the initial packet rewrite chain (including chunk send entry/exit).
• Implementation of hidden/replacement dual-pass and major visibility propagation.
• Semantic alignment for core configs: lava-obscures, use-permission, update-radius, and max-block-height.
• engine-mode: 3 (layer-based) semantics are now operational.
• Integration of Bit-storage direct writing and packet-local palette re-encoding.
• Asynchronous initial packet rewriting: "Main Thread Snapshot + Worker Thread Rewrite + Main Thread Send" with synchronous fallback on failure.

Ongoing Refinements:

• Minor implementation differences compared to the original Paper codebase.
• Potential discrepancies in high-pressure complex cave scenarios; these will be refined in future updates.
