Rence Posted February 2, 2018 Share Posted February 2, 2018 (edited) Hi there, I am stuck and need some advice. I have particles travelling up and colliding with a collision object, in this case a sphere. The particles stop at place of contact and I am trying to figure out how to get them to keep moving around along the surface of the collision object. Scene file attached! Thanks so much in advance!!

Atom Posted February 2, 2018 Share Posted February 2, 2018 (edited) What about something like this... Collect the particles that just hit the surface in a group. Then do further processing on that group using the minpos function to collect the surface position of the collision sphere. Use the grain solver to space them out on the surface and follow up the popnet with a slight push to keep them moving. ap_pop_slide.hipnc Edited February 2, 2018 by Atom Quote Link to comment Share on other sites More sharing options...
Rence Posted February 2, 2018 Author Share Posted February 2, 2018 Thank you so much Atom! That's exactly what I need! I was on the right track. I had grouped the points that hit but then didn't know what to do, so thank you very much! Quote Link to comment Share on other sites More sharing options...
