Holographic remoting without VR Preview (UE-4-26)

Hi there,
I have a question regarding holographic remoting

I use 4.26 version, and is there any way that I can do holographic remoting with hololens 2, without VR preview?
I dont want the square box behind in the VR preview setting

Like Unity holographic remoting, is there any way that I can play the model only?

Thanks a lot!

No, that’s the workflow.

I don’t know what you mean by that? Can you elaborate?

Thanks for the comments.

I mean the translucent square in the preview streaming result
As you can see the end result of streaming, you could see the translucent square box. Is there any way that I can remove/conceal this one? Thank you!
