 So, buttles are your thing, not a problem. DT just means smoothness, the higher the value the more choppy the effect will be, gravity direction X, Y and Z just determine what direction the particles will fall, X determines left and right, Y determines up and down, and Z determines forwards and backwards. The bigger particle life, the longer each particle will stay alive, spawn angle X and Y, change the direction and angle the particles start from, X makes the particles start from a more horizontal angle and Y pivots the rotation from the top. The higher spawn direction random, the more random the particles will go all over the place. Spawn distance is how long the particle has to travel, before it reaches its destination. The higher spawn rate factor, the more particles get instantiated. The higher the spawn speed, the faster the particles will travel. 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. Again, I never really changed normal factor, but you can mess with it here. The bigger particle life, the longer each particle will stay alive. The higher the opacity, the more prominent each particle becomes. The higher the print speed, the more sticky the particles get. And the higher the velocity factor, the less likely the particles are to leave a mark. Of that helps and as always, hope you have a fantastic day and I'll see you around.
