Radius

Sets the radius of the particles. Set any floating-point pixel value using the treadmill.

Spacing

Sets the space between the center of the original position of the particles. Set any floating-point pixel value greater than 2 using the treadmill.

Wind Speed

Sets the wind speed. Set any floating-point pixel value using the treadmill.

Wind Direction

Sets the source direction of the wind. Set any floating-point value in degrees using the treadmill; 0 degrees is 3 0’clock, positive values move counter-clockwise.

Front Speed

Sets the speed of the movement of the wind source. Set any floating-point value using the treadmill.

Air Resistance

Sets the air resistance; this controls how quickly a particle reaches the full speed of the wind.

Set any floating-point value greater than 0.01 using the treadmill; the higher the value, the more quickly the particle will reach the full speed of the wind.

Bumpiness

Sets the bumpiness of the particles. Set a floating-point value between 0 and 1 using the slider.

Time

Sets the progression of the animation. Set any floating-point value using the treadmill. The larger the difference in the time value between keyframes, the faster the effect will happen.
