About Only One Item
From ModrinthA Fabric mod that unifies duplicate items in modpacks by replacing them at the data loading stage, ensuring consistent recipes, loot tables, and faster world loading.
This mod is designed to unify duplicate item types that appear in large modpacks (for example, multiple kinds of tomatoes or silver ore). Commissioned by @Limit小火柴, it is mainly created for the Utopia modpack to standardize various items, but it can also be used in other modpacks or on servers. Unlike One Enough Item, this mod starts replacing items during the data loading stage (including recipes, loot tables, etc.). In other words, anything loaded in JSON format, such as recipes, can be replaced—meaning world loading speed will not be affected. If you are using an item manager, this mod currently only supports JEI (since that’s what the Utopia modpack uses).
You can modify related settings in config/oneitem.json. Example format (this will replace farm_and_charm:wild_onions and farm_and_charm:onion with farmersdelight:onion):
"farmersdelight:onion": [ "farm_and_charm:onion", "farm_and_charm:wild_onions" ]
