Since I'm creating a whole thread, I might as well make it worthwhile. I would like to create a dynamic sky like I see in some pictures.
How do I get a sky like this?

Props to plantoris on the picture.
How do I get the bar around the car like it is in this video? This look like it was meant to replace tunnel testing.
One more thing, I heard TCM talking about a grass pack he had in one of his streams. Are there grass packs to download? I searched on here, but maybe I missed it?
