 So, you don't know how to fracture, not a problem. DT just means smoothness, the higher the value, the more choppy the effect will be. The lower spawn speed, the bigger the delay between when you click and when the particle starts to grow. The higher the life, the longer the particles will stay active. The higher the speed, the faster the particles will move before they die. The higher speed factor at trigger, the longer the lines will be before they start to branch out. The higher stop speed ratio, the less the lines will start to branch. The higher the trigger deviation, the more obtuse the branch angles become. The higher the trigger time max, the longer each line can wait before branching out. The lower the trigger time min, the earlier each branch can start branching out. The higher turbulence power is, the more each branch will start to bend and curve. And the more turbulence scale, the more curvy the designs will get. Hope that helps and as always, hope you have a fantastic day and I'll see you around.
