  1. Hello Everyone, I have just create tutorial of making tornado with VEX using quaternion to control velocity field in Houdini 17. Check in here: https://www.cgcircuit.com/tutorial/tornado-with-vex Best Regards, Nhan Vo
  2. Updated Tornado Setup

    Hi all, I found this awesome setup for creating a vortex around a line by using point cloud data but its being created using a POPVOP in a dopnet. Would anyone know of a more updated method? I'm mainly wanting the great velocities from the base that spiral up the line. Any info or setups would be great to see based on the file. Thanks! tornado_v01.hip
  3. Curve attract Particles problem

    hey all, I have a curve, which is attract particles. Everything is fine, BUT the outer particles only fall down without a curveforce... SO I like to make a tornado with particles. but the outer particles fall down... how can I delete them or make attract to the curve?? and you can see in the screenshot that the inner particles a attract to the curve but the outer are fallin' down... tornado problem.hipnc
  4. create Tornado

    Hey all.. is there a trick, how can I made fast and easy in houdini a tornado, so with smoke and other stuff....I mean not a 1 hour tutorial on YouTube. like in the movie "Into the Storm" thanks for advance
  5. Wax/chocolate tornado

    Hi all. I have some issue and want to make Wax/chocolate tornado animation. From bottom to top. Something like this https://vimeo.com/110055200 But visually more to this I tried Pop particles and Flip fluid, Flip fluid gives better look, but pop particles can die. Flip fluid can`t die, maybe I wrong. Can suggest how to achieve this look?
  6. Hello! I'm new to Houdini, please help!!! I need a small tornado from the fountain that enveloping the character's arm. I try to do this in a simulation, but I can not get a stable beautiful shape. I've tried to do custom velocity field like that too (https://www.youtube.com/watch?v=z19fxCbe2Eg), but still don't get stabil tornado shape. Also,I noticed that if I make a simulation in real size, then it is even more unstable and not beautiful(maybe I'm doing something wrong). The tornado should react to changing the position of the hand (hand is mooving back and forth). And do not know how to achieve the shape of whilrpool,as at my picture. Please, help! armGeo.obj armFX_experinemtal2.hipnc

  8. Vortex shape controls

    Hi all, Am testing/playing with some vortex setups, and came across this super tornado thread w/ scene files that I've been using as a solid starting point: http://forums.odforce.net/topic/13344-creating-simple-tornado-motion-using-pointcloud/ I started to emit points from various sources/shapes, and had the idea to try and get the rising points to not conform to a circle around the vertical curve, but rather maintain the emission shape while funneling up & with an increasing radius. I've tried using a curve force for this & have got results close to hat I'm going for, but the particles always seem to want to confirm to a tight circle around the vertical curve rather than the base shape & funnel outwards. Would anyone have any tips of how to create a custom 'perimiter' for the particles to rise around so they adhere closely the base shape while the vortex gradually increases in radius? Any tips or nudges in right direction much appreciated as always. vertical_outward_vortex_test_001.hip
  9. Hey all, just a shoutout that next week Alessandro will give a presentation at the Los Angeles Houdini User Group: https://www.meetup.com/LA-Houdini-User-Group/events/235146114 Wednesday, November 30, 2016 7:30 PMto 10:00 PM Framestore LA 8616 National Blvd, Culver City, CA (map) Please join us for a presentation by Alessandro Pepe! Alessandro will present production workflows to tackle challenging tasks like ink underwater and tornado FX. He will first cover the overall workflow and then the setup inside Houdini with simplified examples. Topics covered: ● Dealing with hundreds of millions of particles ● Clustering ● Particles Gap Filling ● Taming a Pyro Sim into a tornado ● How to add complexity at render time (a quick overview to Volume Procedural Shaders). Mid-Advanced Level Class: This class assumes a basic knowledge of Houdini SOP, DOP and SHOP contexts. -- In case you can't make that one, the next one will be on Dec 15 @ Gnomon: https://www.meetup.com/LA-Houdini-User-Group/events/235771747/ LA-HUG Meetup: Using Booleans and Volume Meshing to Fracture Geometry Thursday, December 15, 2016 7:30 PMto 10:00 PM Gnomon — School of Visual Effects, Games & Animation 1015 N CAHUENGA BLVD , Los Angeles, CA Perhaps see you there!

  10. Need help on Tornado simulation

    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
  11. hai all, im really beginner with this tornado setup, and want to achive like those refference '' " really admire this tornado fx i have check all tornado sample from this forum, but still didn't get of nice control for my tornado velocity (similiar with those refference video), my velocity didnt want to rotate follow the source velocity point. can some help me where the wrong was, why didnt achive like video reff like above. this the hip file.

  14. custom pyro pressure

    Hi,guys. Recently, i want built a tornado like pyro, a huge storm. The image come form man of steel,Alexander Lombardi Fx Reel ,https://vimeo.com/84196857 Before it , i have to list a better way to drive smoke rotate. So there is a simple test which include a tube source and a vortex force, i'm just add the vortex to the vel filed, after a while, you can see the smoke looks like a dish. I don't know if it was a nature shape, most like the air in middle was all been push out, so the air on top and bottom be attract in. So i have to find a way to disturbance to vel, first i want do it by pressure, high pressure air flow to low pressure lead to a wind, is it right? So i inject a custom pressure field, i not clear with how pressure working in pyro, i can export the pressure filed or modify it, but the pyro simulate not change at all, even i set the pressure to 0. Second way i modify the vel field directly, at the few frame of beginning, the vel field was direct to middle soon, i built a gradient field of the vel.y , if it great a value, then slow down the vel, it clamp the vel totally, although the smoke not rotate crazy, but it also lose the nature detail. I will keep optimize the second way. If anyone lead me a better way to built the tornado storm, or explain me how pressure working will be great. Thanks. pyro_pressure.hip
  15. I have been at this project for a while now and am so sick of this not working. I just can't seem to make the tornado spin around the right way and be more directed by the particle movement. Can someone tweak this and give it back or merely give some suggestions based on the file? That would be awesome! Description: Particles emitting from circle based on surfaces. Volume from Tube for velocity input. Made normals controller to direct toward center of tunnel and down. Emitting fluid from particles using pyro solver from the billowy smoke shelf tool. Thanks so much!! Tornado with fluid_fuel try3.hip
  16. Tordando,

    Hi, I've tried to create stylized tornado sim, please post your opinion about it.
  17. Hey everyone! So I've been working on this tornado sim for quite some time. I have the particles doing what I want them to, but adding the smoke sim has given me a ton of trouble. I've gotten the particles to emit the smoke, but I can't get the smoke to follow the particle path, it just creates a ton and becomes a horizontal effect as opposed to a vertical tornado 0_o. What I think it comes down to is, how do drive the smoke with the velocity and direction of the particles to keep it from sprawling out all over the place and staying contained in the walls of the tornado? If anyone could take a look at my scene and help me out I would greatly appreciate it:) Brandon Tornado_WIP_V4.hip
