Currently we are working on a new snowy terrain. We are still discussing about its name. It looks really fine to me. I took this screenshot from Unity viewport, so its not the final look. I will capture a video as soon as possible. If you wondering how do we create this terrains, we are using world machine which is giving A LOT of possiblities to us to create realistic terrains. After creating it in World Machine, we render hightmap (for hight value) and splatmap (for texture layers) outputs. Then we import them to Unity terrain.
