Controls Tab
The Controls tab contains all the primary controls necessary for customizing the directional blur
operation.
Type
This menu is used to select the type of directional blur to be applied to the image.
 Linear: Linear distorts the image in a straight line, resembling the scenery that appears
in the window of a speeding train.
 Radial: Radial creates a distortion that originates at some arbitrary center, radiating
outward the way that a view would appear if one were at the head of the train looking
forward.
 Centered: The Centered button produces a similar result to linear, but the blur effect is
equally distributed on both sides of the original.
 Zoom: Zoom creates a distortion in the scale of the image smear to simulate the zoom
streaking of a camera filming with a slow shutter speed.
Center X and Y
This coordinate control and related viewer crosshair affects the Radial and Zoom Motion Blur
types only. It is used to position where the blurring effect starts.
Length
Length adjusts the strength and heading of the effect. Values lower than zero cause blurs to
head opposite the angle control. Values greater than the slider maximum may be typed into the
slider’s edit box.
Angle
In both Linear and Center modes, this control modifies the direction of the directional blur. In
the Radial and Zoom modes, the effect is similar to the camera spinning while looking at the
same spot. If the setting of the length slider is other than zero, the effect creates a
whirlpool effect.
Glow
This adds a Glow to the directional blur, which can be used to duplicate the effect of increased
camera exposure to light caused by longer shutter speeds.
