Snow Mesh Trail Renderer v2.0
Use the Snow Mesh Trail Renderer to draw a 3d mesh trail in your winter environment. Exclude obstacles (e.g. a slide box in a snow park) that need no trail by using a layer mask or by rendering the trail on terrain only. Additionally, the trail will be drawn only on the ground, it will stop drawing while in air. You can also use this asset in other environments than snow, replace the textures and draw your trail in the desert!
