VR Multiplayer: Client joining host server doesn't load visuals

Hey all,

I’m trying to get a VR multiplayer project up and running - just with 2 people for now - but when the client joins the server, only a black screen shows and the map doesn’t seem to load.
I.e - The menu widget to select host/join loads fine, but once they select ‘join’ it only shows a black screen whereas host is in the correct map.
Same behaviour if I try running just a dedicated server and joining from another computer. The server log says that the client successfully joins but only the black screen loads.

I’ve tried the same project just with 3rd person and no VR and hosting/connecting between 2 computers works just fine.

So the computer hosting works fine in VR, however as soon as introducing the 2nd VR player it doesn’t seem to work.

I’m using two separate computers, one using Vive Pro and the other just a Vive, both using UE4.21 and using Steam Online Subsystem.

Is there something else I need to be doing when configuring multiplayer for VR?

bump,
im having this issue too, my client connects as a server
