Via Datapacks

Items can easily be excluded from RRV using the c:hidden_from_recipe_viewers common tag adopted by Fabric and NeoForge in 1.21. Using this tag ensures that all recipe viewers that respect the tag (JEI, REI, EMI, EIV, RRV, etc.) will not display your item without needing dedicated integration.

RRV respects this tag for blocks, items, fluids, enchantments, and potions.

Via Resource Packs

The Item View can be easily modified by adding JSON files to assets/<namespace>/rrv/index. The format is as follows:

• replace: An optional boolean stating whether the index should be entirely replaced with this new index.
• values: An optional array containing either Item or ItemStacks to add to the index.
  • Specifying after when adding an item stack will place it after a specific item in the index.
  • Specifying before when adding an item stack will place it after a specific item in the index.
• remove: An optional array containing either Item or ItemStacks to be removed to the index. Specifying an item will remove all ItemStacks of that type.

  "replace": true,
  "values": [
    {
      "components": {
        "minecraft:stored_enchantments": {
          "minecraft:aqua_affinity": 1
        }
      },
      "count": 1,
      "id": "minecraft:enchanted_book"
    },
    {
      "id": "minecraft:water",
      "after": "minecraft:grass_block"
    },
    {
      "id": "minecraft:water",
      "before": "minecraft:grass_block"
    },
    "minecraft:water",
    "minecraft:stone"
  ]
}

Mods that prefer having dedicated RRV integration (wanting to hide more complicated ItemStacks, or changing the index at runtime without a virtual resource/data pack) can also make use of various methods in ItemView to include and exclude items as well.

Including Items

• ItemView.addStackSensitive adds item stacks to the index.

Excluding Items

• ItemView.excludeItem and ItemView.excludeItems exclude instances of Item.
• ItemView.excludeEnchantment exclude resource keys representing an Enchantment.
• ItemView.excludePotion and ItemView.excludePotions exclude holders representing a Potion
