Using the Element Controls
The Elements Controls panel displays the individual controls that accompany each Element, Sprite and Element Preset. Read the full list of Elements on this page.
In the Lens Designer, the Elements panel displays the gallery of Elements. You access the Elements panel by clicking the triangular Open/Close button, located along the right side. The keyboard shortcut for opening/closing the Elements panel is 'E'.
Variety in the Controls
The Elements Controls will update as you select an Element in the Elements Panel. Each element has a different set of controls, so the control options will change as you highlight different Element types. If you do not select an Element, this area will be blank.
As you drag the sliders, the Preview Window will update in close to real time. The value changes made to each Element will be reflected in the Preview Window.
By default, Knoll Light Factory aligns an Image Sprite to the center of the flare. This means your Element will automatically rotate so its X-axis is in line with center point of the flare. If you uncheck Align to Source, the Image Sprite is imported without any rotation applied.

Use this to create a wide elliptical element or a circular elliptical element. Turned off by default.
When the checkbox is checkmarked, the Chroma Fan is elliptical. This simulates a common aspect of using anamorphic lenses in cinematography in which light reflections in the lens appear elliptical. When the checkbox is off, the element is round, since light reflections appear round in spherical cinematography.
When should you use this? The wide circular anamorphic flares only happen with anamorphic lenses, and anamorphic lenses are used to shoot wide-screen motion pictures. Super35 and 16mm motion pictures, and film shot with television and video cameras use ‘flat’ lenses. It is not technically correct to use an anamorphic flare in a Super35 film or a television show. Similarly, the blue horizontal stripe seen in many anamorphic flares is an artifact of the way anamorphic lenses are built, so you won’t see them in film shot with flat lenses.

This control is based on the real-life role of the aperture in a camera. Aperture is the physical opening of the diaphragm inside a photographic lens. Like the iris of an eye, Aperture controls the effective diameter of the lens opening. This diameter controls how much light comes through to the film or image sensor, and helps to regulate the degree of exposure to light.
Aperture affects the overall diameter of the Aperture Reflection element. We suggest that you stay in mid-range values for Aperture Offset. Values that are too high or too low cancel out its effect.
Used by: Aperture Reflection
Sets the size of the Chroma Hoop. The word 'apogee' refers to an orbit around the earth. When you increase Apogee Scale, you are increasing the orbit of the Hoop.
Low values make the Hoop smaller. High values make the Hoop larger.
Note that the Position control sets the baseline for the Hoop sizing. Apogee Scale will only scale down to that baseline. If you want a smaller hoop, you need to set Position closer to the light source.
Used by: Chroma Hoop
Arc Completeness sets how much of the Hoop's circle is filled with its effect. The effect of Arc varies depending on what Apogee Scale (see above) is set to. To get the most of Arc, you should experiment with different Position and Apogee Scale values.
At low Apogee values, Arc more or less does what it says. High values of Arc causes the Hoop to become more circular. Low values of Arc chops down the Hoop to just a section.
At high Apogee values, Arc sort of squishes the arc inwards instead of truncating it, especially when Arc is set to a low value.
Used by: Chroma Hoop
Applies a blur to the Sprite. Set to 0 by default, which means no blur is applied. The value determines how much of that blur is applied, measured in percentage. The higher the value, the more heavily the blur will be applied.
Used by: Image Sprite
Sets the brightness of the element. High values make the element brighter. Low values make the element less bright and more transparent.
Scale and Brightness combine to set the overall strength of the effect. Lower settings will have the effect fade off quickly. Higher settings will add sharp white streaks of light.

Sets the color of the center Stripe line, which is visible if Render Center Line is turned on.
Used by: Stripe
Center Fade checkbox, Center Fade Rate
This checkbox and slider control how the Element will behave as it reaches the center or edges of a comp. The Center Fade checkbox activates Center Fade Rate.
At a value of 1, the Element will be at full opacity along the edges of your comp, but fades as it reaches the center of your comp. At a value of 50, the Element is at full opacity at all locations in your comp. At a value of 100, the Element is at full opacity at the comp center, but fades as it reaches the comp edges.
Used by: Single Poly, Image Sprite
This expands the inner circle of the element, creating a transparent hole in the center. High values make the inner circle look larger and thicker.
TIP: By adjusting Center Offset of a disk instead of Inside Ramp, you can create a hard edged inner circle. If you use Inside Ramp to create the transparent center, you will always have a soft edge.
Used by: Disk, Ellipse

The fan in a Chroma Hoop is made up of many rays of color. Density sets how many rays are there and therefore how solid the Fan appears. At low values, the Fan will appear to be more faded and transparent because there are fewer rays creating it. High values create more rays and a more solid looking fan.
Used by: Chroma Hoop, Chroma Fan
Turned on by default. Makes the Inner Color active, which produces a multi-colored effect.

A 'ramp' means going from transparent and ‘ramping up’ to fully opaque. You will see a smooth gradient of color going from barely visible to a solid color. The Inside Ramp defines how big this ramp is coming out from the center of the disc. The larger the value, the larger the soft area going up from center to the mid-point of the ring.
TIP: If Inside Ramp is set to 0 and Center Offset is larger than 1, there will always be a solid center or a hard edge on the inside of your ring.
Used by: Disk, Ellipse
Increases or decreases the length of the Stripe element.
Used by: Stripe
Maintain Aspect Ratio checkbox
Locks the Scale X and Scale Y controls together so their aspect ratio is preserved as you change the size of your Image Sprite. If you'd like to stretch out the Sprite, uncheck this box.
Used by: Image Sprite
Sets the color of the position and orientation marker on the preview window.
Used by: Guides
This option is not really a transparency-to-opacity ramp. It sets the width of the band between the Inside Ramp and Outside Ramp. If Middle Ramp is set to 0, then you will see a thin, bright band of color defining the transition of Inside to Outside. Otherwise, you’ll see a band of solid color. The larger the value of Middle Ramp, the thicker that band of solid color will be.
TIP: Usually the Disc looks like a shaded sphere, with soft edges everywhere. By setting Center Offset to 1 and Inside Ramp to 0, setting Middle Ramp to any value larger than 0 will result in a thick, solid color disc.
Used by: Disk, Ellipse
Determines how ‘noisy’ the effect is. Do you have a soft glow or sharp streaks? Low values add a soft blend to the effect. Higher values create more visually noticeable noise.
Used by: Aperture Reflection, Chroma Hoop, Chroma Fan
Adds more or less noise pattern to the element.
Used by: Glow Ball, Circle Spread, Single Poly, Disk, Ellipse, Vertical PolySpread

Toggles how the Sparkles move out from the center. When the checkbox is active, the Sparkles move uniformly from the center. When it's inactive, they move randomly from the center with slight variances in angle.
Used by: Sparkle
Sets the color of the outer area of the glow. This is the dominant color.
Used by: Glow Ball, Element Strip, Aperture Reflection
At its default settings, this option sets the radius of the Disc or Ellipse. As soon as you have anything in the center, Outside simply determines how far beyond the Middle Ramp area it takes to fade back to complete transparency. High values make the outer edge of the sphere larger and more feathered.
Outside Ramp is the inverse of the Inside Ramp, as Outside goes from a solid color and ramping down to transparency. This creates a halo around the element.
Used by: Disk, Ellipse
Most of the elements have a Position control. This position is always along a line that passes through both the center of the image and the light source.
A value of 1 places an element at the light source. A value of 0 places an element in the center of frame. A value of -1 places an element on the opposite side of the frame from the light source.

Tilts the Barrel elements along the Y plane.
Used by: Barrel
Width sets the size of the central point. Low values narrow the point, with a value of 1 creating a very sharp point. High values make the point thicker.
For Star Filter, the rays will not overlap at standard Width values. However, you can manually set Width to high values by typing a value into the numeric field. This will cause the rays to overlap and create interesting looks. Also for Star Filter, if the Thick checkbox is selected, then Thickness works in conjunction with Width to set how wide the rays of light are. You also want to look at how many rays have been set with Count. The Count value will affect how wide a ray has to be to start overlapping.
