Wearables

Wearables are the entities that contain items for players to wear and customize their avatars.

The wearables field in a player’s profile contains a list of pointers to the items they are currently wearing.

Every wearable belongs to a category, indicating the spot it takes on the avatar’s body, and can hide or replace other categories (for example, a long dress may be worn as top clothing but entirely cover the legs).

There are 18 wearable categories, referenced in various metadata fields: body_shape, hair, eyes, eyebrows, facial_hair, mouth, upper_body, lower_body, feet, hat, helmet, mask, tiara, top_head, earring, eyewear, skin and hands_wear.

Wearable entities include files in GLB format for different body shapes.

Pointers #

Wearables have exactly one associated pointer , which indicates the collection they belong to and their identifier inside of it.

When the wearable is an on-chain asset, the pointer is a URN of this form:

urn:decentraland:<blockchain>:collections-v2:<collection address>:<item index>

To illustrate, the pointers array for an on-chain wearable looks like this:

{
  "pointers": [
    "urn:decentraland:matic:collections-v2:0x2d9560df9dd8ba8b2dc3746bc1d217698d258fb5:0"
  ],
  // ... other entity properties
}

When the wearable is an off-chain asset, such as the default wearables for new avatars, it will be of this form:

urn:decentraland:off-chain:<collection>:<item name>

The collection in this case is a name, not an address, and the item identifier is also a name rather than an index.

The pointers array for an off-chain wearable has this look:

{
  "pointers": [
    "urn:decentraland:off-chain:base-avatars:BaseFemale"
  ],
  // ... other entity properties
}

Metadata Fields #

Wearables share most of their basic fields with emotes . The data property is where the wearable-specific information is located.

Field	Value
`id`	The pointer that resolves (or used to resolve) to this wearable.
`name`	The display title for this wearable in a collection .
`description`	An extended description for this wearable.
`image`	The internal filename of a picture for this wearable.
`thumbnail`	The internal filename of a 256x256 version of the `image`.
`rarity`	One of `common`, `uncommon`, `rare`, `epic`, `legendary`, `exotic`, `mythic` or `unique`.
`i18n`	An array of translations for the `name` field.
`collectionAddress`	The Ethereum address for the collection that contains this wearable.
`metrics`	Some useful measurements about the animations (see below).
`data`	The extended metadata for this wearable (see below).

In typical JSON form:

{
  "id": "urn:decentraland:matic:collections-v2:0x11a6879861f36cbad632b4e7226816a16139fb33:0",
  "name": "Pretty Dress",
  "description": "Very nice to wear",
  "image": "image.png",
  "thumbnail": "thumbnail.png",
  "rarity": "uncommon",
  "i18n": [
    { "code": "es", "text": "Vestido Lindo" }
  ],
  "collectionAddress": "0x11a6879861f36cbad632b4e7226816a16139fb33",
  "metrics": {
    // Measurements object (see below).
  },
  "data": {
    // Extended metadata (see below).
  }
}

Metrics #

In the metadata.metrics object, you’ll find some simple measurements for the models packaged with this wearable. An example:

{
  "entities": 1,
  "bodies": 12,
  "materials": 2,
  "meshes": 12,
  "textures": 2,
  "triangles": 3321
}

Data #

The metadata.data object is where the wearable-specific properties are located.

Field	Value
`category`	One of the wearable categories listed above.
`representations`	An array of files associated to different body shapes (see below).
`hides`	An array of categories this wearable hides.
`replaces`	An array of categories this wearable replaces entirely.
`tags`	An array of string labels descriptive of this wearable.

Representations #

Each item in the representations array associates a body shape with a collection of models, and can add rules regarding which wearables are displayed in each category.

Field	Value
`bodyShapes`	An array of pointers to body shape entities.
`mainFile`	The 3D model file to start the rendering.
`contents`	An array of filenames (present in the top-level `content` field ) used by the `mainFile`.
`overrideHides`	Supersedes the `hides` list above for this representation.
`overrideReplaces`	Supersedes the `replaces` list above for this representation.

This is a typical representations item:

{
  "bodyShapes": [
      "urn:decentraland:off-chain:base-avatars:BaseFemale"
  ],
  "mainFile": "male/190.glb",
  "contents": [
      "male/190.glb"
  ],
  "overrideHides": [ "lower_body" ],
  "overrideReplaces": []
}
