Hey TechLord,
Good to hear from you. Your new game with time-space dimensional rifts looks kewl. It is interesting that you mention streaming scene-capture/render targets from one server instance to another, because I was asked about this recently by a prospective client. There is a communication channel system built into UE4 for communicating between servers, this may be a possible way to do that. The problem I see is that streaming video data in real-time is probably going to be expensive, but would definitely be something interesting to look into more. I was also planning on looking into server to server communication to “show” players locations beyond the zone boundaries of a server instance. That seems like a bit less data to transmit, but the idea is still the same. I will let you know if I come up with anything useful.
