Lootr Polymer Patch

Lootr is a mod that makes all containers inside structures spawn with per-player loot so that every player can loot structures without having a large perimeter around spawn devoid of loot.

This mod patches Lootr to work completely server-side. That is, vanilla clients can join and use the mod. This mod must be installed alongside Lootr and its dependencies.

Lootr containers render as their vanilla counterparts, with a small block icon. By default, this is a gold block for containers that the viewing player has not opened, and a lodestone for containers they have opened. This is configurable.

This mod also removes Lootr's advancements & stats, leaving only the functionality and making it a great drop-in for SMPs.

Currently, all 26.x versions are supported, likely well into the future. Lower versions are unlikely to gain support unless highly requested.

./config/lootr_polymer.json default:

{
  "lootr_indicator": true,
  "opened_indicator": "minecraft:lodestone",
  "unopened_indicator": "minecraft:gold_block"
}

Restart the server to apply changes.
