Would not the rotation be the reverse of what is shown to make it appear as if the sun was rising in the East?

Nice, planned to share ?
Also like my version, is planned to have the moon have a different period for moon phase and also the sky ?

Maybe if I have a new computer and can test if it works with newer SpaceEngine versions than SE 0.973.

The sky, the sun and the moon have different rotations. The sun moves over the sky once a year and the moon overtakes the sun once in about 28 days.
Of course, this is not visible in this short animation.

If my version work, it should be worked with the new version. Or maybe you use a different method if you don't use your under like you experiment flat planet I used for my version, so you can't go to the surface but I think in the next version, we can use object instead the method actual.

OK, like my version, is just I think for the gif you don't show the rotation of the Earth (~24 hours) ? Because else, it doesn't explain why the night is different each night if the skybox turn also.
