  1. Hello everyone! I am very new to Houdini an need some help. I am trying to rebuild ""FLUID SOURCE" node with container settings "collision" to use it later in DOP with "Smoke Solver" and importing collision with "Source Volume". Just now have made with VDB surface field called it "collision" and create one more VDB from attribute "v" called it "collisionvel". I see difference between FLUID SOURCE and VDB collision is in first one create 3 scalar velocity fields and the second create one vector velocity field. Setup with VDB now have a problem my density ( made with "Source Volume") : theres no adding to density from SOP , but it works like copy. I will appreciate for any help! Thanks! P.S. Also i am interesting to rebuild it all without smoke solver, so feel free to comment all around this problem!
  2. Hi Guys, I just started learning about smoke simulation. I am trying to create a tornado simulation using smoke solver instead of Pyro. I followed the custom force tutorial from Ben Watts. The problem that I am facing is that when I start my simulation, after a while the smoke spread out and remains floating and it doesn't follow my velocity field. How can I get it to follow my velocity all the time, or is there anyway to kill the smoke based on their age? I have attached a quick preview and my hip file. Thanks, Preview.mp4 Tornado_test7.hiplc
  3. Hey everyone, I'm still kinda new to Houdini and right now I'm trying to get a similar effect like it is shown in this video https://vimeo.com/110820797. I used one of the animated characters in Houdini and put the 'Billowy Smoke' "onto" it. The effect works, but I still have some issues which I can't solve by myself. At around frame 45 the smoke man is not displayed completely anymore. The legs kind of disappear. To check this issues, I also took a sphere as the smoke emitter and I noticed that the sphere already was not fully displayed in frame 1. You'll see the issues on my screenshots. I have really no clue what's causing this and therefore I hope some of you can help me solving this. Thanks in advance, r4ZR smoke.hip
