  1. Trail SOP help

    Hi all, I'm having what I'm expecting is a very simple issue with the trail SOP. As my points are dying/ptnum is resetting, I'm getting glitches at the ends of my trails. Obviously if it was a POP sim, I could just trail > cal vel, then append an add SOP to ad a primitive based on id, however I can't figure out how to do it using the @ ptnum variable in the attribwrangle. Is @ ptnum is actually just the wrangle variable, and not actually the point attrib? Been scratching my head on this for a while. .hipnc attached, any help very much appreciated.broken_trails.hipnc
  2. Recently I discover something interesting after smash my head against wall for a few days. Im creating a simulation using bullet and packed prims, and I need activate (using i@active variable ) the pieces in choreographed way over the frames But the thing make me crazy is that bullet change ptnum of each packed primitive over the time, and I think is about some priority list inside the algorithm of the solver. because after the simulation I need to atach some atributes for each simulated piece. Then I realize that I need to attach theses attributes before simulation or atach some sort of ptnum tracking for them. bullet activate order points_v001.hip
