Notes

Minecraft loot tables are a very complex system, which is made to be used in many ways (block and mobs drops, dungeon chests, plant harvest etc...) and that would be a hell to support and test all possibilities of loot tables. So some things may break, other may not work.

Loot tables have a type property, when possible use "type": "custommachinery:custom_machine". It may not be needed thought.

If you have any issues with the loot table requirement and you seek support in the github issues or in the discord, please include the loot table file and describe the most precisely possible what it should do. I am not a loot tables expert and I can't spend hours on the wiki just to understand what your loot table does.
