Define the sliding Direction</link>. From -5 to 5.
Default is 0
Controls</link> display persistence, i.e. the “fade to black” amount for a frame. Lowering this value retains past particles longer, whereas increasing this make them disappear faster.
Enable</link> / Disable sliding blur.
Controls</link> the radius of the blur effect applied to past particles. Particles are “smeared” more and more as they become older, depending on this setting. Naturally, a bigger value increases the smearing, at the expense of processing power.
Choosing the value for this setting is really matter of taste, although please keep in mind values that above 5 will require a sufficiently powerful graphics card in order to maintain a responsive display.
