Natural Wonders - Iceland is a collection of Nanite meshes, which can be quickly added to your level to build a stunning background. There are 30 unique meshes with varying features; from grassland and hills to sharp rocky mountain ridges and volcanos. Each mesh has two material variations, a barren and a lush one. With a material collection parameter you can control the snow line from having no snow on the terrain at all, to a completely snow covered scene.

Additionally there are eight different fog cards which can be hand placed to add fog and more visual apeal to your environment.
