The Glow effect adds a bright soft-edged light or diffuse light region around an image. The Glow effect is useful in creating a shining rim around objects such as the sun or stars.
Use the Glow editor to control the direction of the blur that creates the glow, as well as its colour.
Glow Effect Properties
|Truck Factor||Activated by default, this option readjusts the blur when the elements undergo a change of depth or scale. When this option is deselected, the effect's values remain unchanged regardless of any depth or scale changes. This option should be deselected when multiple drawings are composited and attached to this effect.|
Directional: Blurs the matte in the direction you select. For example, if a character is walking east, the blur may fall to the west.
Radial: Blurs the edges of the matte evenly around points that make up its edge.
|Radius||Enter a value for the size of the blur. The larger the value, the greater the blur effect. The blur radius is affected by the drawing scale and camera position.|
If you select a Blur Directional type, you can select the direction of the blur by entering a value from 0 to 360 in this field.
|Directional Fall-off Rate||
The distance where the blur fades from the edge of the image. Select a value between 0 and 1.
|Invert Matte||Inverts the matte used to create the glow. The matte will become a black silhouette while the glow fills the background space.|
|Use Source Colour||Uses the colours painted in the matte for the glow effect. If you deselect this option, select a colour and alpha values in the Colour section.|
|Multiplicative||Creates a more diffused glow.|
|Colour||Lets you choose the colour and alpha values for the glow effect.|
