Hello! Thanks for using it!
Unfortunately space views are not supported yet, so it works best for planar worlds so far.
Before the release of the plugin I actually had support for space views, especially for stars, but it did make the SkySphere material to be quite expensive, so I postponed this feature.
And there was lots of compromises! To my understanding, UE4 isn’t very good with handling such gigantic space distances, even if you shrink down Planet Size to a few hundeds of kilometers. Various graphical artifacts appear on SkyAtmosphere and so on. I may be wrong, but that was my experience. I’d like to revisit space views feature some time later though.
