Snowy Peaks comes with 18 Trail Morphs on the snow surface, which allow you to set a variety of end points to place your characters and the depth of the path. There are also two “camp” morphs offering a wider space, e.g. to place a Bivouac.
The set also includes a noon and a sunset HDRI/Skysphere.
The trails look better in Iray than in 3Delight, at least if you dial in some depth. The shading on 3Delight looks a bit too hard imo. Thus I recommend using the Iray version if that´s an option.
