This is a sky overlay, meaning that you can put this on top of your current resource pack. All that will change is the nighttime sky. OptiFine is recommended for a better experience. You can set your sky to nighttime only with a time changer mod on Lunar Client.

Thanks for downloading!

If the sky isn't working, make sure that:
- You're using OptiFine
- You have custom skies on
- You unzipped the .zip file.
