simonliu Posted December 22, 2016 Share Posted December 22, 2016 hi everyone, i have a destruction cache from maya, i use trail to compute velocity and transfer to speed; i group some points base on speed (e.g speed >= 8), and scatter to generate smoke; but speed keep changing, if the point speed less than 8, i will lost it and result in my smoke trail is broken... so how can i constantly keep these points if their speed is greater than 8 once?
