I'm a little late to the party on this one, but it's almost exactly what I've been looking for and thanks for sharing here. Now a couple of questions before I run off and do something that obviously won't work:
Can the ring setup be used as a clip file for a planet object seen in the sky from the "home" planet? I notice that that's where they are now.
Or can they be applied to a multiple disc objects in lieu of the SS shader? I have one of my own making and it's fairly good, but not quite all of what I'd like it to be.
Anyway, here's mine if you want to have a look. Once the clip is inserted, the planet should appear in the sky with the default startup.
