A very basic low poly foggy forest rendered using Vray plugin. Includes 2D trees. Suitable for quick rendering. It's not a complex 3D scene. As a 3D artist i know many occasions when time pressure forces you to use good looking quick solution before deadline. Again it is a good solution for artists facing deadline and so on.
As of rendering. The idea is to use it as a silhouette, rather than a lit daylight scene. This is why most of scenes are hazy. Have fun.
