Create Hero Characters

Create unique Hero Characters for your application.
A Hero Character is a complete avatar by any means. It supports all elements of a Ready Player Me avatar, including accessories, hair and body, for example.
Following these guidelines you can provide a fully prepared custom avatar for the Ready Player Me platform.
Example Hero Characters can be downloaded here.
Take these files as a reference of a functional Hero Character.
The examples include blend shapes on the head mesh for facial animation support.
Check the documentation on morph targets.
Alternatively, you can create an avatar using a Ready Player Me Avatar Editor, and download it with certain options: ?textureAtlas=none&morphTargets=ARKit,Oculus Visemes

Hero Character Requirements

File Requirements

  • File type: .GLB
  • File Size: max. 10 MB
Do not use custom glTF-Extensions extensions in the file, e.g. Draco mesh compression.

Armature

An Armature is a skeleton that is responsible for deforming the avatar during animation. It does so by a process called linear-blend skinning, for which each vertex on a mesh, aka skin, needs a set of weights that determine by which joint in the skeleton they are going to be influenced.
You can download fullbody templates here. Use the masculine or feminine skeleton.
Ready Player Me avatars have either a feminine or masculine shape, each based on separate skeletons. When creating an avatar, it must use either the feminine or masculine skeleton.
Do not include animations in the exported GLB file.

Meshes & Materials

General Requirements for Meshes, Materials and Textures

Maximum total triangle count: 30000 You decide how to distribute triangles across meshes. We recommend to use as few triangles as feasible and put details into the texture maps.
Skin weights: Required for ALL meshes Implementations of the gltf 2.0 specs are only required to at least implement 4 skin weights per vertex. Therefore, Ready Player Me assets only support a maximum of 4 skin weights per vertex. Skin weights for each vertex MUST be normalized, meaning they have to add up to 1.0!
Vertex colors: No

Texture files format: PNG 24 bits per pixel. Do not use palettes (8-bit color indexed). Do not include metadata or color profile information in the PNG image file to avoid errors.
BaseColor maps: Required for ALL materials Use sRGB (IEC 61966-2-1 Default RGB color space) when editing the image.
Normal maps: Optional OpenGL tangent space normal map, +Y up.
Metallic-Roughness maps: Optional
Occlusion maps: Optional We recommend to pack the occlusion map into the red-channel of the metallicRoughnessTexture. See Blender documentation on how to export it.
Emissive maps: Optional
Maximum texture resolution: 1024 x 1024 pixels Texture resolutions must be square and power-of-two, e.g. 128x128, 256x256, 512x512.
Maximum individual texture file size: 2 MB

Double sided materials: Optional We recommend to use as few double sided materials as possible.
Not all of the following meshes are needed. Only include the meshes you need for the custom avatar you have in mind.
It is possible to only use a single mesh for the whole avatar with a single material. In that case we recommend using the wolf3d_body mesh.
The head of the avatar.

  • Material name: Wolf3D_Skin

The head mesh supports morph targets or facial animation. See documentation on morph targets.

Uploading a Hero Character

Ready Player Me Studio

Using the Ready Player Me Studio interface, you can navigate to the Asset Manager, and then choose Add new asset, or directly go to https://studio.readyplayer.me/asset-management/new.
In the Type selection, you must select Hero Character as the asset type.
In the Gender selection, choose the option matching the skeleton you based your asset on.
Upload the necessary files and Save. The asset is only saved when it passes validation. If any errors are detected regarding the compliance with the requirements, you'll get a notification and more information.

API

When you want to push your assets to your organization at Ready Player Me, use thePOST - Create AssetAPI endpoint with the data.type set to costume. Once the asset is created, the files will be stored by Ready Player Me.
If you don't have the files yet available at a public URL for use with the Create Asset API endpoint, you can use the temporary storage solution provided by us via the POST - Upload Asset Filesendpoint.
