GET https://models.readyplayer.me

Get an avatar 3D GLB model with desired performance and configuration settings.

Path Parameters

Name	Type	Description
avatarId.glb*	String	ID of an avatar.

Query Parameters

Name	Type	Description
quality	String	low, medium or high - Use quality presets to combine performance related parameters.
meshLod	Int	Controls the triangle count of the avatar.
textureSizeLimit	Int	Sets the upper limit for texture resolution in pixels of any texture in the avatar.

morphTargets	String	Comma-separated list of individual morph targets or morph target standard groups to include on the avatar.
useDracoMeshCompression	Boolean	Reduces file size by compressing output avatars with Draco mesh compression. More effective on complex meshes.
useMeshOptCompression	Boolean	Reduces file size by compressing output avatars with Mesh Optimization compression. More effective on meshes with morph targets.

Parameters, expected values, and examples

You can combine multiple parameters by concatenating with &.

So for example requesting an avatar with meshLod 2 and without texture atlassing would look like that:

https://models.readyplayer.me/6185a4acfb622cf1cdc49348.glb?meshLod=2textureAtlas=none

Parameters, expected values, and examples

/avatarId.glb

ID or Shortcode of an avatar.

Expected values (String)

• 6185a4acfb622cf1cdc49348.glb

• ABC123.glb

Notes

You must include the .glb file extension or you will get a 404 return value.

You can get an avatar id or short code via postMessage returned from Ready Player Me. You can read more about how to do that at Native Integration.

Without any of the optional parameters, the avatar is returned based on default values.

Examples

Request avatar by ID

https://models.readyplayer.me/6185a4acfb622cf1cdc49348.glb

Request avatar by short code

https://models.readyplayer.me/ABC123.glb

Returned value

You will receive a standardized .glb file. You can import and modify this file in any 3D software that supports this format.

?quality

Use quality presets to combine performance related parameters from below.

Expected Values (String)

• low

• medium

• high

The values behind those presets are the following:

• low (meshLod=2, textureSizeLimit=256, textureAtlas=256, morphTargets=none)

• medium (meshLod=1, textureSizeLimit=512=textureAtlas=512, morphTargets=none)

• high (meshLod=0, textureSizeLimit=1024=textureAtlas=1024, morphTargets=none)

All other values overwrite quality. So e.g. you can use quality=low and overwrite the LOD with 0 to get the high-res avatar. See Examples.

Example

Request an avatar with quality high

https://models.readyplayer.me/6185a4acfb622cf1cdc49348.glb?quality=high

Request an avatar with quality medium

https://models.readyplayer.me/6185a4acfb622cf1cdc49348.glb?quality=medium

Request an avatar with quality low

https://models.readyplayer.me/6185a4acfb622cf1cdc49348.glb?quality=low

Request an avatar with quality low but overwrite meshLod

https://models.readyplayer.me/6185a4acfb622cf1cdc49348.glb?quality=low&meshLod=0

?meshLod

Control the triangle count of the returned avatar.

Expected values (Number)

• 0 - No triangle count reduction is applied (default).

• 1 - Retain 50% of the original triangle count.

• 2 - Retain 25% of the original triangle count.

Examples

Request an avatar with meshLod 2

https://models.readyplayer.me/6185a4acfb622cf1cdc49348.glb?meshLod=2

?textureSizeLimit

Set the upper limit for texture resolution in pixels of any texture in the avatar.

Expected values (Number)

The value needs to be a multiple of two.

• Min: 256

• Max: 1024 (default)

Examples

Request an avatar with textureSize limited to 512 x 512

https://models.readyplayer.me/6185a4acfb622cf1cdc49348.glb?textureSizeLimit=512

?textureAtlas

Generate a texture atlas of the desired resolution. This operation merges all meshes and splits opaque objects from transparent ones resulting in a maximum of 2 draw calls.

The texture atlas is generated for all PBR channels - baseColor, normal, metallicRoughness, emissive, and occlusion, if any of the assets making up the avatar includes them.

Expected Values (String, Number)

• none - Do not create a texture atlas (default).

• 256 - Create a texture atlas of 256x256px.

• 512 - Create a texture atlas of 512x512px.

• 1024 - Create a texture atlas of 1024x1024px.

Examples

Disable texture atlas:

https://models.readyplayer.me/6185a4acfb622cf1cdc49348.glb?textureAtlas=none

Create 512px texture atlas:

https://models.readyplayer.me/6185a4acfb622cf1cdc49348.glb?textureAtlas=512

Atlasing on - 1 draw call (without transparent objects)

Atlassing off - 9 draw calls (without transparent objects)

?textureChannels

Select the texture channels you want to have included in the .glb. (By default, the .glb comes with all available channels).

Expected Values (String)

• baseColor

• normal

• metallicRoughness

• emissive

• occlusion

• none

You can combine these values by comma separation. See examples.

Examples

Get avatar with no textures

https://models.readyplayer.me/6185a4acfb622cf1cdc49348.glb?textureChannels=none

Get avatar with only baseColor and normal map.

https://models.readyplayer.me/6185a4acfb622cf1cdc49348.glb?textureChannels=baseColor,normal

?morphTargets

Comma-separated list of individual morph targets or morph target standard groups to include on the avatar.

Expected values (String)

• Default

• ARKitst

• Oculus Visemes

• + or any supported morph targets.\

The default value is "Default".

Examples

Disable all morph targets

?morphTargets=none

Use selected morph targets ?morphTargets=mouthSmile,mouthOpen

Use morph target standard groups ?morphTargets=ARKit,Oculus Visemes

Use selected morph targets and standard group ?morphTargets=mouthSmile,ARKit

Example:

https://models.readyplayer.me/6185a4acfb622cf1cdc49348.glb?morphTargets=mouthSmile,ARKit

?pose

Define the pose for a full-body avatar.

Expected values (String)

• A - Create a full-body avatar in A pose (default).

• T - Create a full-body avatar in T pose.

Only applies to full-body avatars.

Examples

Create an avatar in T-pose

https://models.readyplayer.me/6185a4acfb622cf1cdc49348.glb?pose=T

Create an avatar in A-pose

https://models.readyplayer.me/6185a4acfb622cf1cdc49348.glb?pose=A

?useDracoMeshCompression

Reduce the file size by compressing output avatars with Draco mesh compression.

Expected values (Boolean)

• true - Enable compression.

• false - No compression (default).

Draco mesh compression is disabled by default for maximum compatibility for various glTF loaders.

Examples

Request an avatar with Draco mesh compression turned on

https://models.readyplayer.me/6185a4acfb622cf1cdc49348.glb?useDracoMeshCompression=true

?useMeshOptCompression

Reduce the file size by compressing output avatars with Mesh Optimization compression. This technique is more effective on avatars with morph targets.

Expected values (Boolean)

• true - Enable compression.

• false - No compression (default).

Mesh Optimization compression is disabled by default for maximum compatibility for various glTF loaders.

Examples

https://models.readyplayer.me/6185a4acfb622cf1cdc49348.glb?useMeshOptCompression=true

?useHands

Toggle hands for half-body VR avatars.

Expected values (Boolean)

• false - Do not include hands with half-body VR avatars.

• true - Include hands with half-body VR avatars (default).

Only applies to half-body avatars.
