Paper Per World Config

World settings are configured on a per-world basis. The child-node default is used for all worlds that do not have their own specific settings. For more information about how per world configuration of Paper works, see the Per World Configuration Guide. For global config, see the Paper Global Configuration Reference

disable-teleportation-suffocation-check

mobs-can-always-pick-up-loot

map-item-frame-cursor-limit

  • default: 128
  • description: The number of cursors (markers) allowed per map. A large number of cursors may be used to lag clients.
  • default: true
  • description: Whether the server should check if a chunk's biome (determined by world seed) can support the desired feature before loading it during feature searches. This dramatically reduces the number of chunks loaded during feature searches.
  • note: This assumes the seed and generator have remained unchanged. If your seed or world generator has been changed, features will be located incorrectly.

seed-based-feature-search-loads-chunks

  • default: true
  • description: When set to false, seed-based-feature-search will not load the target chunk. Instead, it will return the center of the chunk. The more precise location of the feature will be returned as the player loads the target chunk. While disabling this will increase performance, it may lead to incorrect feature locations being returned. This will impact both the /locate command, buried treasure maps, and any other game mechanic that relies on feature searches.

  • description: Allows players to use signs while inside spawn protection.

      • hide-durability
        • default: false
        • description: Controls whether durability information is sent to other players' clients. This may break resource packs that rely on durability values when observing other players.

feature-seeds

  • generate-random-seeds-for-all
    • default: false

  • <feature-namespace>: Sets the population seed for the specified feature. If set to -1, the Vanilla population seed stays unchanged and will not be overridden by the autofill option either.

split-overstacked-loot

  • default: true
  • description: When set to false, loot tables will not attempt to split items with a stack size higher than the maximum into items of smaller stack sizes. This will prevent overstacked items from being lost or causing a chunk to become uninhabitable (due to players getting constantly kicked because of oversized packets) when a shulker box is broken in survival.

monster-spawn-max-light-level

  • default: -1
  • description: When set to -1, the Vanilla default will be used (=0). Set to 15 or greater to revert to pre-1.18 behavior.
