WHO IS ALTARAntiESP MADE FOR?

ALTARAntiESP is made for server owners who want stronger protection against ESP, radar, xray, and freecam-style client abuse. It is useful for SMP, survival, factions, lifesteal, earth, towny, prison, and competitive servers where hidden underground activity matters.

It is especially useful for servers where players build underground bases, secret tunnels, private farms, vaults, mob farms, or hidden rooms that should not be exposed through hacked clients.

• Survival servers with underground bases.
• Factions servers with hidden vaults.
• Lifesteal servers with secret player locations.
• SMP servers with private farms and tunnels.
• Competitive servers where information leaks matter.
• Staff teams that need extra moderation tools.

WHY USE ALTARAntiESP?

Many client-side cheats work because the server sends more information than the player should realistically know. ALTARAntiESP focuses on reducing that information before it becomes useful to the client.

Instead of only relying on alerts or punishment after a player has already received hidden data, ALTARAntiESP masks and filters protected underground packets when PacketEvents is installed.

IMPORTANT NOTE

ALTARAntiESP is designed to reduce leaked client-side information and make ESP, radar, xray, and freecam-style abuse less effective. No anti-cheat or anti-ESP plugin can honestly guarantee perfect protection against every private or custom client.

The plugin is built with configurable settings so server owners can balance protection, gameplay feel, and performance for their own server.

HOW ALTARAntiESP WORKS

ALTARAntiESP works by controlling what protected underground information is sent to the player client. Many ESP, radar, xray, and freecam clients depend on packet data that the server already sent. ALTARAntiESP helps reduce that data before it becomes useful.

• Step 1 - Viewer Check: The plugin checks the viewer's location, world, permissions, and configured reveal level.
• Step 2 - Protection Level: If the viewer should not see underground data, ALTARAntiESP applies the configured hide level for that world.
• Step 3 - Chunk Masking: Protected chunk sections below the hide level are replaced with a configured mask block such as deepslate, stone, or air.
• Step 4 - Light Masking: Underground light data is filtered so caves, lava, torches, and hidden rooms are harder to detect through light patterns.
• Step 5 - Entity Filtering: Underground players and mobs are hidden from viewers who should not be able to track them.
• Step 6 - Packet Filtering: Protected block updates, sounds, particles, and spawn packets are filtered when they are below the configured hide level.
• Step 7 - Reveal Logic: When a player legitimately goes underground below the reveal level, protected data can be shown again according to your configuration.

EXAMPLE

If a player is standing on the surface and another player is hidden underground, ALTARAntiESP can prevent the surface player from receiving useful underground chunk, light, entity, sound, and particle information. This helps reduce the effectiveness of ESP, radar, xray, and freecam-style clients.

CONFIGURABLE PROTECTION

Server owners can adjust the hide Y level, reveal Y level, mask block, per-world settings, blacklisted worlds, entity hiding, lower chunk distance, and packet masking options. This allows ALTARAntiESP to fit different server types and gameplay styles.
