Custom Items
Identifier Formats
Section titled “Identifier Formats”oraxen:<item_id>itemsadder:<item_id>ecoitems:<item_id>The prefixes can be used for recipe source and result items. Menu item materials in messages.yml also accept them.
Loading
Section titled “Loading”If one of the supported providers is enabled, Item Upgrader waits addons.wait-for-addons-to-load ticks before registering recipes. Until registration completes, /itemupgrader returns the configured loading message.
Troubleshooting
Section titled “Troubleshooting”If a provider is missing or an identifier cannot be resolved, Item Upgrader logs a severe message and falls back to stone for that lookup. Check exact case and namespace, confirm the provider loaded successfully, increase the addon delay if necessary, and reload the recipe after the custom items exist.
Only the first detected provider among EcoItems, Oraxen, and ItemsAdder controls the delayed registration message, but recipe item lookups can still use any installed supported provider.
