yeah the tech preview for T2 makes planets if you zoom out far enough! perfect for spacescapes! t2 is very confusing at first, but once you get used to everything, then its easier than the first one. give it a try!
I love the water and lighting detail, but I don't like how you can only see the mountain silhouette in the distance, and the water just kinda fades away on the sides, but the center is all sharpened out.
