– This parameter sets the maximum value for the direction’s variation of the velocity vector.
– It’s expressed as percentage value of 180°, so 0.1 means 18°, 0.2 means 36° and so on.
– The larger this value the larger the variations of particle’s direction.
– In this example you can see how the bigger this value the smaller the circle is (as the particles can change their direction with bigger angles)
