jonathanC13 Posted October 15, 2018 Share Posted October 15, 2018 Hey ! I am creating a sandstrom with the billowy smoke in Houdini. I was wondering how I can get rid of this mushroom clouds that is popping out of the sandstrom after 3-4 seconds ? I have added 2 render is the attachment. One of frame 32 , where the look is good of the sandstorm and one of frame 173 , where you can see those big mushroom clouds. Quote Link to comment Share on other sites More sharing options...

DonRomano Posted October 17, 2018 Share Posted October 17, 2018 You can play around with differents gasdisturb nodes sets on differents Block Size (I like to put 2 nodes with 0.3 and 0.1), and you can add a control field based on temperature or velocity, so it can avoid the mushroom effect. It's also possible to add some gas vortex confinement, or add noise to your temperature to drive the velocity field differently. I just attached a quick made file that show how to avoid it based on velocity. Hope that helps Smoke_avoid_mushrooms.hipnc Quote Link to comment Share on other sites More sharing options...
