philippecounter Posted February 9, 2022 Share Posted February 9, 2022 Hello everyone, I hope you are doing well. I have a little question. Is it possible to control my simulation so that it is attracted by my tube? Like a pop attract, but for smoke ? I made a first simulation to have my base, which I freeze to import it into a second dop, the one in which I would like to "attract" my smoke towards the tube...

dleonhardt Posted February 9, 2022 Share Posted February 9, 2022 You can make a fog volume from the tube, negate it and source it into the Divergence field. 1 Quote Link to comment Share on other sites More sharing options...
ThisIsDolan Posted February 9, 2022 Share Posted February 9, 2022 An easy way to do this, if your torus is in the center of the world, is to add to the velocity the minus normalize Position in a Gasfield VOP. See the screenshot attached : The value inside the Multiply is -1 (change it according to the speed you want it to be attracted to the center of the world).
