Thank you Joseph for such a thorough answer. Since I was on tight schedule had to figure out something by myself since no answer came yesterday. It worked out well, altough I’ve used a different technique than yours. I used two particle systems both of them on a motion path copying the V blade, so at the beginning the particles go from the front to the sides and then straight on along the car, it worked pretty well, though not perfect. I had to add two more particle systems to create a more likely “fog” of snow, so that there would be variation. But your suggestions seem more logical to me now (:

Thanks again for taking time to respond.
