Rendering Features

Rendering features are owned by the UE renderer container. The client SDK does not expose live animation coefficients or browser-side avatar playback for current hosted calls.

Player Surface

const { rendererPlayerUrl } = useAStackCSR({ session });

return rendererPlayerUrl ? (
  <iframe title="AStack renderer" src={rendererPlayerUrl} />
) : null;

Renderer Ownership

Character assets, lighting, camera behavior, materials, and animation playback live in UE.
Worker-to-UE coefficient delivery is verified from renderer logs and playback status telemetry.
Browser acceptance checks validate WebRTC audio/video continuity, not client-side animation frames.
