Thanks Skybar and loopyllama for your advice!

Hi all, I simulated snow above my Torus. I've created a vector (0,1,0), and then I calculate the dot product between my vector and normal. More than 0.4 snow, less than 0.4 no snow. But I wouldn't like the snow when my Tourus is at 90 degrees, or when the top of the Torus cover the hole of the Torus. How can I think to do that? I am attaching two photos to make you understand better (I hope :-) ) Thanks!

Thanks malexander, you have been very kind and super fast! Thanks again!

Hi all, I am following this video: https://www.youtube.com/watch?v=6POfEu9-ILA Unfortunately, I can't contact the teacher. So, I ask you, I have tried similar threads in the forum, but I haven't found. I apologize if this topic has already been treated. I am attaching 3 photos, taken from the video. How I can make Houdini so colorful? Thank you all.
