ARVps2Asset
> extends UnityEngine.XR.ARFoundation.ARTrackable
Represents the origin of a VPS asset tracked by the device.

---

## Declaration

public sealed class ARVps2Asset : ARTrackable<XRVps2Asset, ARVps2Asset>

## Remarks

The trackable's transform follows the asset's origin as VPS refines the
localization, so content authored in the asset's coordinate space is placed by
parenting it under this trackable. While the asset is not fully tracked, the
tracking state degrades to Limited and the transform keeps the last known
pose.
