 So, you're a big fan of being organic. 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 opacity, the more the fade. The higher the fade opacity random, the more unpredictable the fade becomes. The higher fade size, the more the ends of the particles shrink as they fade. The higher fade side random, the more unpredictable the size of the ends of each particles are as they fade. If you want it to look like the particle was tossed from a direction, you can make it inherit velocity. And I believe this is dependent on the strokes of your mouse. The bigger particle life, the longer each particle will stay alive. The more random the life, the less likely each particle is to die at the same time. The higher the speed, the faster the particles will travel. The higher the speed random, the more likely the particles will travel at different speeds. The higher the spawn rate factor, the more particles get created. The more turbulence power you have, the less straight the lines become. And the more turbulence scale, the more the lines start to wave back and forth. Hope that helps and as always, hope you have a fantastic day and I'll see you around.
