Lootr Polymer Patch

The patch applies Lootr's per-player loot chests on a server without any client-side work. Players who join with an unmodified vanilla client can open the containers, which appear as their vanilla equivalents tagged with a block icon. Lootr containers use the default gold block, and a container shows as opened only for the player who opened it, whether it is a chest or a lodestone container. Naturally generated chests in ruined portals appear unopened to each player, left opened or right opened.

Lootr Polymer Patch has to be installed alongside the Lootr dependencies on a Fabric server. The mod removes Lootr's advancements and stats and keeps only its functionality, which suits drop-in survival multiplayer servers. Server owners restart the server to apply changes. It is released under the MIT License and is open source, with the source code published. Files cover 1.21.6 – 26.3 across 11 release versions, and 26.x is the line the author expects to keep supporting. Support for older releases is not planned unless users ask for it in large numbers.
