  2. 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!

  3. Hi, I am an experienced Software Engineer with a good eye for Visual Effects. I have over more than 10 years of experience in developing advanced software systems for simulation and animation companies. In addition, I've invested that last 5 years exploring and educating myself all about Visual Effects. Below is my demo reel.

  4. 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
  5. 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
  6. 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.

  7. Help with a Tornado

    I am new in houdini and i am having a really difficult time creating a tornado alto I've done it a hundred times in Maya and 3Dsmax fumefx can someone guide me or send me an easy to understand hip i found no useful tutorials in this

  9. 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
  10. Tordando,

    Hi, I've tried to create stylized tornado sim, please post your opinion about it.
  11. 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
  12. 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
