Lucio,
Thanks for more than just the clip file.
I have been wrestling with this issue for a while and you not only gave me a way to create a great glacier but second you reinforced for all TG2 users the power of the node network and third, you opened a door, you gave us a way to think about the the solution of problems like snow creation.
Your clear explanation along with the diagrams is a job well done!
