• Shape pattern selection
• Set the size, degree of deformation, softness, and
rotation angle.
Ring settings
Shines the light with a hole in the middle, like a doughnut.
Adjust the following parameters.
Offset: Distance to move the center of the ring from the
initial position (the position set when selecting the
light source in the <Spot Mode> group).
Radius: Inner side radius of the ring.
Angle: When Offset is set, the rotation angle of the ring
around the initial center position.
Fill blending modes
Specifies the way in which the light is blended with the
image.
Mix: Lighting as if reflected from a mirror. The light
source can be given a color.
Multiply: Lighting as if reflected from a dull surface
(diffuse reflection).
Relation between test spheres and parallel
light rays
The following figure shows an example of the effect of
parallel rays on a test sphere.
The direction of the light is defined by longitude and
latitude.
• Longitude: A direction (angle), expressed as a plus value
for clockwise rotation in the plus direction with respect
to the X axis of the input picture.
• Latitude: Latitude
The following figure shows the relationship between the
longitude and latitude of parallel rays, input picture, and
test sphere.
The measurement unit of direction parameters is the number
of rotations, with 360
°
(1 rotation) expressed as 1.00.
The following relationships apply in the example shown in
the figure.
The fractional part of the setting after the decimal point
corresponds to an angle 0° to 360°. If the fractional parts
of two setting values are the same, the effect is the same
even if the integral parts are different.
The integral part of a setting value is used when moving a
light source with keyframes.
For example, when the longitude of a light source rotates in
the clockwise direction from 0.88 (315°) to 0.12 (45°), it
rotates in the counterclockwise direction (the angle grows
smaller) if the above values are used. In this case, the value
of the second keyframe can be set to 1.12 (360° + 45°).
