haggi Posted July 25 Share Posted July 25 The pop network outputs the velocity of the particles, so why do not use it? You delete everything except the id and then you try to recreate the velocity with a trail sop. Looks a bit strange to me. Quote Link to comment Share on other sites More sharing options...

haggi Posted July 26 Share Posted July 26 Then try to use the id attribute in the trail sop, this may help for the calculation. Quote Link to comment Share on other sites More sharing options...
