prashantcgi Posted September 8, 2014 Share Posted September 8, 2014 Hi Everyone! I'm facing a issue while using this node Pop Advect by Volumes. The problem is :- Advected particles using volume is sticking on the bounding edges of volume, how can i make them leave the volume. i'm also using the velocity scale parameter in pop advect by volume node. but my particles are sticking on the edges on volume outer edges. Please help. Thanks Quote Link to comment Share on other sites More sharing options...
Annon Posted September 8, 2014 Share Posted September 8, 2014 I usually do something like copy the density to the particles, if the density is below a threshold make them ballistic and add their own forces/noise to them. Quote Link to comment Share on other sites More sharing options...
Annon Posted September 8, 2014 Share Posted September 8, 2014 I think this does it if I remember rightly. H13_advectPoints.hip Quote Link to comment Share on other sites More sharing options...

eetu Posted September 8, 2014 Share Posted September 8, 2014 Trying a minimal example, I can't get the particles to stick to the edges. By default they just keep on going. For fun times you can set the volume border condition to repeat, this way the volume affects your particles everywhere in a wrapped fashion - might be a good or a bad thing. ee_popadvect.hip Quote Link to comment Share on other sites More sharing options...
