aviator Posted November 14, 2017 Share Posted November 14, 2017 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 Quote Link to comment Share on other sites More sharing options...
RejectedMoose Posted November 14, 2017 Share Posted November 14, 2017 Have you tried 'Suction Force'? Quote Link to comment Share on other sites More sharing options...
aviator Posted November 18, 2017 Author Share Posted November 18, 2017 I have. But the suction force pushes the particles forward a little, increases speed and changes the shape. But I need to create a shape that is in the picture. Also the whirlpool should appear and rotate slowly Quote Link to comment Share on other sites More sharing options...
moneitor Posted November 20, 2017 Share Posted November 20, 2017 what about a more procedural approach like this, I am not saying that it couldn't be done using particles, but this seems like the kind of things I would approach splitting the effect in different parts, one would be the waterfall, and the other one would be the wrilpool, and then at the end I would mix everything with secondary particles, spray and stuff like that. armFX_experinemtal2.hipnc Quote Link to comment Share on other sites More sharing options...
moneitor Posted November 20, 2017 Share Posted November 20, 2017 This one have a vop that allow you to change the shape of the whirlpool using a ramp armFX_experinemtal2.hipnc Quote Link to comment Share on other sites More sharing options...
dyei nightmare Posted November 20, 2017 Share Posted November 20, 2017 looks like some spiral velocities pulling some flips Quote Link to comment Share on other sites More sharing options...
