Hi, I trying to add all mod (forestry) to stage with one method. And all OK, but some items(like bees, butterflies, saplings) with different but similar MBT don't want to add using this method. What I must do?

Generally you would use a * as the metadata to define a wildcard for all sub-items. Some items with complex NBT will require stages to be applied on a more specific basis.

// All lvl 5 enchantments
mods.ItemStages.addItemStage("one", <minecraft:enchanted_book>.withTag({StoredEnchantments: [{lvl: 5 as short}]}));

// All enchanted books
mods.ItemStages.addItemStage("one", <minecraft:enchanted_book:*>);
