Tuesday is the new Wednesday, did you know? Here is snapshot 23w04a with a new experimental Armor Trim Smithing feature in the Update_1_20 experimental pack.

Happy trimming!

CHANGES

• Enchantment glint on items and armor is now more subtle

EXPERIMENTAL FEATURES

• Added a new armor trimming system to visually customize your armor
• Added Smithing Template items
• Redesigned the Smithing Table
• Changed how Netherite equipment is crafted

SMITHING TEMPLATES

• Smithing Tables have been redesigned into a workstation for physical equipment upgrades and modifications
• Alongside slots for combining a piece of equipment and materials, there is now a required slot for an item type called Smithing Templates
• Smithing Templates define what type of upgrade you will be making to equipment
  • It specifies both what type of items you can upgrade, and which ingredients are valid to customize the upgrade
  • There are currently two categories of Smithing Templates: Armor Trim and Netherite Upgrade
• Smithing Templates are consumed when used to upgrade an item in the Smithing Table
• You can craft a copy of a Smithing Template in the Crafting Table with 7 diamonds + 1 block of material that the template is made out of + 1 smithing template, which will output 2 of the same Smithing Template

NETHERITE EQUIPMENT

• Netherite equipment crafting now also requires a Netherite Upgrade Smithing Template
• Netherite Upgrade Smithing Templates can be found randomly in all Bastion Remnant chests, and there is a guarantee of 2 in every Treasure Room Bastion Remnant
• This change was made for a variety of reasons:
  • Increase the time players utilize Diamond equipment before Netherite
  • Make Netherite equipment a more significant achievement in the game's progression
  • Adapt Netherite more naturally into the new Smithing Table crafting system

ARMOR TRIMS

• You can now visually customize your armor with a variety of unique trims at the Smithing Table
  • All armor is viable for trims except for leather armor
• Armor trims are purely visual with no gameplay benefits, and can only be applied to Helmets, Chestplates, Leggings and Boots
  • All trim patterns are visually the same on an armor's item icon, but the color will still change based on the trim material
  • To check which trim pattern a piece of armor has, you can hover over it in the inventory
• Armor Trim Smithing Templates can be found all throughout the world, and each of the following structures contain their own unique Smithing Template:
  • Pillager Outpost
    • Sentry Armor Trim
  • Desert Pyramid
    • Dune Armor Trim
  • Shipwreck
    • Coast Armor Trim
  • Jungle Temple
    • Wild Armor Trim
  • Ocean Monument
    • Tide Armor Trim
  • Ancient City
    • Ward Armor Trim
  • Woodland Mansion
    • Vex Armor Trim
  • Nether Fortress
    • Rib Armor Trim
  • Bastion Remnant
    • Snout Armor Trim
  • Stronghold
    • Eye Armor Trim
  • End City
    • Spire Armor Trim
• Smithing Templates are found in chests in their respective structure, except for the Ocean Monument. Instead of finding it in chests, Elder Guardians sometimes drop a Smithing Template upon death
• Some Armor Trim Smithing Templates are rarer than others, so be on the lookout for them to impress your friends!
• An armor trim has two properties: a pattern and a material
  • The pattern is defined by the Smithing Template used to apply the trim, and represents the visual pattern of the trim
  • The material is defined by what ingredient you used to apply the trim, and represents the color of the trim
• The viable ingredients you can use to define the color of your armor trim are the following:
  • Iron
  • Copper
  • Gold
  • Lapis
  • Emerald
  • Diamond
  • Netherite
  • Redstone
  • Amethyst
  • Quartz
• Armor cannot have the same material it is made of applied to it as a trim
  • For example, a Golden Chestplate cannot have a Golden Armor Trim

TECHNICAL CHANGES

• Added a new type of atlas configuration source:paletted_permutations

• Armor Stands now preserve custom names when placed and broken

• A new registrytrim_patternhas been added for the armor trim system

• A new recipe serializersmithing_transformhas been added for the updated Netherite Upgrade recipe

• A new recipe serializersmithing_trimhas been added for the new Armor Trim recipe

• Smithing table has temporarily two menu types

  • Old menu without Smithing Template slot has been renamed tolegacy_smithing
    • Will be removed when Armor Trim feature stops being an experimental feature
  • New menu with Smithing Template slot was added calledsmithing

• Added new flag (value 128) toHideFlagsNBT field for hiding armor trim item tooltips

PALETTED PERMUTATIONS

• paletted_permutationsis a new type of atlas configuration source used to dynamically generate new textures in memory based on a set of color palettes
• Color palettes allow you to swap out the colors of a texture without having to supply all files for the variants of a texture in a resource pack
• This is useful for things like armor trims, where you want to be able to change the color of parts of the armor without having to create a new texture for each color
• Thepaletted_permutationssource has a set of required parameters:
  • texturesA list of namespaced locations of base textures
    • These textures will be used to generate variants of them that have been modified by color palettes
  • palette_keyA namespaced location of a color palette key file
    • A color palette key is used to define the set of key pixel colors we want to swap out with the color palettes defined below
  • permutationsA map of permutations from suffix to a namespaced location of a color palette file
    • The suffix is appended at the beginning to the resource location of the output variant textures, with a_character separating the suffix and the base texture name
    • The color palette is a texture file with a set of pixels that are used for replacing pixels that match the color palette key in each base texture
    • The number of pixels in each color palette must be the same as that of thepalette_keydefined for this source
    • Key matching is done by comparing the RGB values of each pixel in thepalette_keyto the RGB values of each pixel in the color palette
    • Alpha channel is ignored for key matching, but in the resulting texture the alpha channel is multiplied with the color palette's alpha channel
    • Pixels that do not match thepalette_keyare copied over to the resulting texture as-is
• After defining apaletted_permutationssource, you can then reference those namespaced output textures in other resources in your resource pack
  • For example, if you have the followingpaletted_permutationssource:

    {
        "type": "paletted_permutations",
        "textures": [
            "minecraft:item/leather_helmet",
            "minecraft:item/leather_chestplate",
            "minecraft:item/leather_leggings",
            "minecraft:item/leather_boots"
        ],
        "palette_key": "minecraft:colormap/color_palettes/leather_armor_color_key",
        "permutations": {
            "red": "minecraft:colormap/color_palettes/red",
            "green": "minecraft:colormap/color_palettes/green",
            "blue": "minecraft:colormap/color_palettes/blue"
        }
    }

  • You can then reference the resulting textures in other resources like this:

    {
        "textures": {
            "layer0": "minecraft:item/leather_helmet_red",
            "layer1": "minecraft:item/leather_chestplate_green",
            "layer2": "minecraft:item/leather_boots_blue"
        }
    }

TRIM PATTERNS & MATERIALS

• Trim patterns and materials for armor are defined by the server through thetrim_patternandtrim_materialregistry respectively
  • As a result, new trim patterns and materials can be added via data packs
• These are synchronized to clients when they join the server
  • However, clients must have an accompanying resource pack to see those registered trim patterns and materials
  • The paths to these textures are inferred based on the filename of the pattern json, and will try to find the textures within the same namespace as the trim pattern'snamefield
• The following data is defined by a trim pattern:
  • asset_idwhich is a namespaced id used to infer texture locations and localization
  • template_itemwhich is the id of the smithing template item used to apply the trim pattern
  • descriptionwhich is a text component used for displaying the pattern name of an armor trim when hovering an armor itemstack
• The following data is defined by a trim material:
  • asset_namewhich is a string used as a suffix for armor trim texture locations
  • ingredientwhich is the id of the ingredient item used to apply the trim material
  • item_model_indexwhich is a float which defines the item model override each armor item model should target to change their visuals for this material
  • incompatible_armor_materialwhich is an optional id of the armor material this trim material cannot be applied to
  • descriptionwhich is a text component used for displaying the material name of an armor trim when hovering an armor itemstack
    • The style defined in this description is applied to the armor trim patterndescriptionas well
