The mod was created in two versions, for a single game, and for SAMP. It is not possible to use the two versions together. What are the differences? In the single player version, the stars appear at 21:00 and disappear at 05:00 in SAMP the script does not work! In the version for SAMP, the stars appear when the keys 1 and 5 are pressed together and no longer disappear, along with the stars, the game time and weather change, details are inside the archive.
If you want it to be like in the screenshot, look in the Graf folder inside the archive.
