 So, you just want to draw nasty veins. Not a problem. DT just means smoothness. The higher the value, the more choppy the effect will be. Speed is how long the particle takes to get from the camera to the object. 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 trigger, the more likely the veins are to separate. 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 higher turbulence scale, the bigger and wider the turns will be. Hope that helps and as always, hope you have a fantastic day and I'll see you around.
