Light Rays
A glow filter that uses the zoom blur to distribute the resulting glow, instead of a
gaussian blur. The effect is that of light rays shining through an object from a specified
point.
This filter causes rasterization in 3D groups.
Parameters in the Inspector
Amount: Sets the amount of the light ray effect. Larger values extend the length of the
rays. Values range from 0 to 200.
Center: Sets the position of the center point of the light source.
Glow: Sets the brightness multiplier of the light rays. Values range from 0 to 8.
Expansion: Sets the distance the light rays extend outside the boundary of the source
object. Values range from 0 to 2.
Mix: Sets what percentage of the original image is blended with the filtered image.
Values range from 0 to 100%.
