Modifying Loot or Loot Tables - LootrMinecraft/Lootr GitHub Wiki

Lootr does not provide any methods to allow the editing of loot tables or the contents of chests and containers.

Lootr changes the container that the loot generates in, meaning that multiple players have a chance to have loot generated for them, but does not change the contents.

Lootr uses the exact same method that Vanilla does to generate loot, but it does randomize the seed for each player that opens a container, meaning that loot will not be identical as with Lootr not installed.

If you have issues with loot generation or are concerned that Lootr is somehow changing the loot (unlikely, but very rarely possible), it is recommended that you compare to an identical world without Lootr installed.

It is possible that some mods may check that the specific block the loot is being generated for is, for example, a minecraft:chest, but I am not currently aware of any.

If you wish to change the contents, reduce the quantity of loot, etc, you will need to use tools specifically designed for editing loot tables.

Some such tools include:

• LootJS, a KubeJS addon for modpack developers to modify loot.

Please note that I cannot provide any support for the above tools, and it is recommended that you consult their documentation and support resources if you are having issues.
