Reupload, v2 still need some time ;(
Download, unzip and drop folder to - steamapps\common\assettocorsa\extension\config-ext\Pure\Skydome_sets
Then in game, go into Pure Config - Clouds tab - set clouds set to trapflat one, then set weather to broken clouds, few clouds, scattered clouds, overcast clouds, make sure there's night time.
