Multi Astra Pro Cameras and body tracking


I need to connect at least two cameras with body tracking.
I just tried with 2 Astra Pro cameras and I have some troubles…

When I use the two cameras, no body tracking at all. The body frames disappeared, . I tried to lauch the MultiSensor Sample and this the result :

Just one colour source also.

I use the c# wrapper.

Is it really possible to have multi cam?

I’m also trying to set at least 2 Astra Pro on the same computer and im facing the same kind of problems.
