visual effects + weather radar

[ebbsy1]

hi saw a vid on you tube last night of someone showing off the amazing  icing effect.i asked if it worked in 1.1.7 and got the message back saying that he`s just tryed it out and could not reproduce the effect in 1.1.7.also don't think the weather radar works correctly as i have it set to weather but all it picks up is the terrain
