Whatsinaname Posted June 10, 2017 Share Posted June 10, 2017 (edited) I'm trying to isolate those areas of a FLIP sim, that have been in contact or collided with some geometry. My problem is I've got something that works for the particles as long as they are close to the surface, but as I intend to create some dripping and surface tension effects. At the moment, I am assigning an attribute to the points which are colliding, which allows me to isolate the fluid on the surface, but of course that gets overwritten each frame. There must be a more elegant solution for this, but I cannot figure it out at the moment, so any ideas or feedback pointing me towards a better solution is welcome. collideStick_v001.hipnc Edited June 10, 2017 by Whatsinaname Quote Link to comment Share on other sites More sharing options...
Atom Posted June 10, 2017 Share Posted June 10, 2017 (edited) The attribute only gets overwritten per-frame because you keep setting it back to zero at the top of your PopWrangle. If you simply set i@close equal to zero in an attribute wrangle external to the DOP network then your i@close will work more like a "stuck" flag. You could also just assign a color and inspect for that too. Edited June 10, 2017 by Atom Quote Link to comment Share on other sites More sharing options...
