+
+## Paper Anti-Xray
+
+Enable Paper's built-in Anti-Xray protection in the Nether to prevent players from locating Ancient Debris through lava using transparent lava resource packs.
+
+**File:** `world/dimensions/minecraft/the_nether/paper-world.yml`
+
+Under `anticheat.anti-xray`, configure:
+
+```yaml
+anticheat:
+  anti-xray:
+    enabled: true
+    engine-mode: 1
+    hidden-blocks:
+      - ancient_debris
+      - nether_gold_ore
+      - nether_quartz_ore
+    lava-obscures: true
+    max-block-height: 128
+    update-radius: 2
+    use-permission: false
+```
+
+Restart the server to apply the changes.
+
+**Tested:** Ancient Debris hidden behind lava is no longer visible when using a transparent lava resource pack.
