Error on Live Link | Face, Body, Eye Tracking

 
Hello, hope all is well.

I am trying to get Live Link working on the Meta Quest Pro in Unreal 5.2, and have tried in 5.1 as well. I keep running into these errors in the Live Link window after connecting Meta MovementSDK Live Link.

Live Link Errors:

 

Trying to add frame data that is not formatted properly to role 'LiveLinkAnimationRole' with subject 'Eye'.
Trying to add frame data that is not formatted properly to role 'LiveLinkAnimationRole' with subject 'Body'.
Trying to add frame data that is not formatted properly to role 'LiveLinkBasicRole' with subject 'Face'.

 

 

(My Quest Pro is connected correctly and I can run the Movement Sample without any issues using the official release 5.2/5.1 and MetaXR Plugin and have also built the GitHub version of UE5.2)

Tracking is not working in Editor when not in Play-mode. 

Try VR preview to make it work.

The errors you see are connected to the fact that LiveLink frames are invalid - as these come from the headset marked as invalid.

Do you know of any documentation for the MetaXR Movement SDK live link functions?  I can't find anything regarding this.  There are no examples in their movement sample.  thanks!
