Collaboration Data vs Body Tracking

Hi There,

I want to create a AR multiuser game, so I use Collaboration Data to synch all users AR session.
I also want to use Human segmentation for some features, and switching from People Occlusion to Body Tracking (because both are not supported simultaneously).

If I try to enable Body Tracking at runtime (humanBodyManager.pose3DRequested = true) while using Collaboration Data, I get this warning in xCode :
Requested features not satisfied: 3D Body Tracking

But if Body Tracking is enabled at App Start, I have this warning
Requested features not satisfied: Collaboration

So it seems that those features are mutually exclusive, but I was wondering if it was a ARKit limitation, some ARFoundation bug or something else ? Could someone explain ?

I am using ARKit and ARFoundation packages 4.0 preview

Thanks

 

So for anyone interested, I found an answer here :

tl;dr : AR Collaboration requires a ARWorldTrackingConfiguration but Body Tracking needs a ARBodyTrackingConfiguration, so they cannot work together
