FAQ for Unreal Engine

Frequently asked questions by Unreal Engine developers.

Is there a way to cache (store) avatars locally to reuse them without downloading each time?

Avatars can be cached at runtime if you enable avatar caching. See avatar caching.

Can I create an avatar directly in-engine? Without the web interface?

Yes. The SDK contains an avatar creator sample that can be used for creating avatars, check the QueckStart to see how it works. There is also an option to have a web interface using the WebView plugin, check the Code Samples to see how it works.

How do I use a 3rd person avatar in UE?

See the 3rd person sample projects.

Why is there lag when loading an avatar into a scene?

The performance issues or "freezing" when an avatar loads into a scene is a known limitation of the third-party plugin glTFRuntime we use for handling the import of .gltf/glb files. The freezing should be less noticeable on the built application. To provide a smooth experience for the users, enable avatar caching and use avatar preloading.
