Starry Skies Pack For NFS Heat
You can chose 2 options, Dark Starry skies or a brighter blue starry sky just like in the thumbnail.
This mod only changes the sky, not other visuals like lighting and light poles etc. So it is recommended that you use this mod with one of the unite visuals preset mods for the best looking result possible.
I do plan on porting this into nfs unbound soon.
