Doum Posted February 20, 2014 Share Posted February 20, 2014 I can suggest you, if you have time to take a look at CMIVFX.com houdini network relationship vol1. It related to what you want to achieve and I'm sure you will find some good tricks with this tutorial. cheers Doum Quote Link to comment Share on other sites More sharing options...
Netvudu Posted February 21, 2014 Share Posted February 21, 2014 Indeed. You could also get a good start using the Vortex tab for the Fluid Source SOP on your emitter. Quote Link to comment Share on other sites More sharing options...

indienpz Posted February 24, 2014 Author Share Posted February 24, 2014 Helloso i tried cmivfx approach and obviously had a problem. How to make smoke maintain its form? and not dissipate or expand? hip file(could not attach it in a normal way)\ http://yadi.sk/d/HPMpVCvdJTA9c Quote Link to comment Share on other sites More sharing options...
Doum Posted February 28, 2014 Share Posted February 28, 2014 For the dissipation, there is a parameter in the pyro solver that you can tweak that make the smoke live longer. For the expantion of the smoke, maybe you can create a succion force that will keep your smoke in a reasonnable range from your curve. I cannot take a look at your scene for the moment, maybe you can check the vortex tab as javier proposed and see how it is build. Quote Link to comment Share on other sites More sharing options...

Diego A Grimaldi Posted July 9, 2015 Share Posted July 9, 2015 Check out the file I posted on this thread: http://forums.odforce.net/topic/22547-how-can-creat-vortex-cloud/ It should help you get far enough Quote Link to comment Share on other sites More sharing options...
tricecold Posted July 11, 2015 Share Posted July 11, 2015 Diegos solution will definitely work, but unless its a timelapse fx, supercells are not that fast moving shapes, you can easily get away with a mathcin geo shape rendered as volumes with some deformation.

Netvudu Posted July 11, 2015 Share Posted July 11, 2015 I concur. In fact I did it many years ago with plain geometry and some good photoshop skills. It´s true that doing it with volumes has much more sense, and would help for the puffy look. Quote Link to comment Share on other sites More sharing options...
