**[Eugene Constable]** *"Also all the other variables like scale, complexity, octave multiplier and so on...I cant realy finds any help with these."*
Particular uses Perlin noise to generate the pseudo-random numbers that drive the turbulence field. Scale, complexity, octave scale, octave multiplier are all controls that influence the Perlin noise output. There's a "how it works" section in the documentation (accessible by clicking the "Options..." link at the top of the Particular effect, then clicking the "Help..." button).

If you're more the hands-on type, you can get a pretty quick understanding by turning on Particular > Air > Visualize Fields. You'll very quickly be able to see how adjusting each of the sliders affects the turbulence field, which in turn affects your particles. I find this invaluable for adjusting turbulence fields.
