Hi Magnus, I don't know much about getting ParaView to work in the client-server mode you describe and less about the Unreal engine, but if you are willing to sacrifice a little bit of rendering speed would be to build VTK with OSMesa and let it do software rendering rather than requiring a hardware context (which it can't seem to get due to some interference with Unreal). I just thought I would point out the option, you can try it and decide if you think the rendering speed hit is too much.
