I looked at your earlier file again and it looks like the clouds move when the camera moves in the initial move, they don’t move as much in the second move but that’s because of parallax (building is near clouds are far in a camera truck move with no rotation) and the clouds don’t move in the time change because the camera doesn’t move. Time changes and the stars move because the planet rotates but clouds don’t have to move when the stars do. I think it’s doing what it’s supposed to. If you want cloud change there you’ll have to animate it.
