Mixed reality plugin - how to overlay 3D actors on top of VR spectator screen

Hi everyone !

I’m trying the mixed reality and everything is working fine.

In the calibration process i can see my VR hands overlaying the webcam texture.

But, in my project, I only have the texture and i don’t know how to manage to have some 3D actors on top of the texture.
Is it a parameter on actors or a shading parameter ? Or anything else ?

Can you help me please?

Thanks in advance.


PS: i’m on the 4.20 version.
