Thanks for doing a video review ! Funny thing is i have the ability to rotate the sky but i disabled it because i found it was a bit weird when i was testing. I'm actually rendering 10000 of the brightest stars but half of them are not visible, which is why there are some constellations that are half hidden.
To give you a little hint, the visual of the constellations don't always exactly match with the lines i'm drawing in the sky. The big dipper for example is actually composed of a lot more stars in the sky than what is shown on the picture of the constellation.
