UI does not show up while doing In-Editor Pixel Streaming

I cannot see any UI elements while doing in-Editor pixel streaming. I am using my own remote signalling server.

Hi there!

Can you elaborate on which UI elements are missing?
If it’s widget/HUD elements of your game that do not display during level streaming, this is due to both full editor streaming and packaged projects capturing the back buffer, who’s call is the very last step so everything is rendered properly.
The level editor does does not capture the back buffer and instead relies on a different call which won’t have widgets.
