The Fan effect creates spiralling blade like objects that move around the model either clockwise or counterclockwise. Used most effectively on models such as a mega tree or a matrix.
One or many colors can be used for the effect. If multiple colors are selected, then the blades of the fan will be made up of the selected colors.
Position: Center X,Y
Defines the x and y coordinates of the center (i.e. focus) point of the fan effect.
Position: Radius 1
Defines the lower radius of the fan.
Defines the angle of each arm of the fan.
Position: Radius 2
Defines the upper radius of the fan.
Defines the number of 360 degree rotations per timing mark the effect is in.
Blades: # Blades
Defines how many blades the fan effect will use per color selected.
% of area that the width of each blade will take on the effect.
Angle of each blade from center.
Blades: # Elements
How many segments each blade is divided into - default is 1.
Controls the swell i.e. the amount of time that the fan swells out.
Controls how quickly the fan swells out and then back in.
Reverses the direction of the rotation of the fan effect.
Options: Blend Edges
Each edge blends to black. Turning it off converts the fan effect to a full circle at the end of each swell.
Playing with the radius values i.e. making radius 2 less than radius 1 can provide some interesting effects.
You can create four Fan effects that each take up about one quadrant of your model (matrix/house) and have them all doing different thing with their arms blending at the edges. The four positions would be x25:y25, x25:y75, x75:y75, x75:y25.
