gerd Posted September 16, 2016 Share Posted September 16, 2016 Hallo, i want to group particles that had just collided with an static object. They only should be in the group the timestep of the collision. After that timestep they should not be in the group anymore. In old pops you can use the justhit attribute inside the rule of the pop group node. ($JUSTHIT == 1) greetings gerd Quote Link to comment Share on other sites More sharing options...
Atom Posted September 16, 2016 Share Posted September 16, 2016 I think it has been replaced with DOPs Impact record system. This data only exists on the frame when the impact occurs. But you can setup a solver to record the data to persist over time. I demonstrate such a setup in my particles break Glue Bonds video ~3:20 into it. The video is fairly short, it may help you out.
