Hi Support,
I can’t seem to get the moon to work or stars? When I set the time to 2-4am it sould be dark but just clips out with no light at all, surely at this time you sould get the moon light n stars? How do you use it correctly?
You need to add new Corona Moon object to the scene, the same way as you add Corona Sun, it will not appear automatically based on your time of the day settings.
You also have to watch for exposure, since the regular exposure in a Corona Camera is set for daylight levels, and night time lighting is much less strong 
true, previously made/old Sky and Sun don’t work (no emission/black)
here’s tech demo to get things started (toon, outline, sun, sky, contrails, stars, milky way)
Skylark.c4d (1.06 MB)
Hmm I had this happen before IIRC. I think the PRG sky model didn’t get updated / reinstalled because some of the files were somehow still in use when I ran the installer.
Mind trying to run the installer again?
