Object detection

Drop one UObjectDetectionConsumer component on an actor and detected markers (colored ball/disc trackers) and 6-DoF objects spawn as child actors that follow the live AR 51 tracking feed. The owning actor's transform is the parent/anchor space for everything spawned.

Units

The AR 51 system reports meters; the consumer converts spawned actor transforms to Unreal cm internally. Fields that are not converted — notably UTrackedInstance.Radius and the smoothing thresholds — appear to be in meters as received; see per-field flags.
