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 relationships between the

test sphere.

Setting the surface where light strikes the
image
1
Open the DME >Light/Trail >Spot Lighting menu
(4156).
2
Press [Spot Lighting], turning it on.
Latitude = –0.25
The unit of these direction parameters is the number of
rotations, with 360° (1 rotation) expressed as 1.00, in the
same way as 3D rotation parameters.
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°).
3
Set the following parameter.
Brightness of whole image
•
Lowering the brightness of the image makes
Spotlighting more effective.
•
The Total Ambient setting is shared with the
Lighting function.
4
In the <Surface Select> group, select the state of the
surface struck by the light.
Flat: The image surface is unchanged, causing the
selected light source to appear as the effect.
Texture: A texture appears on the surface of the
image.
Non Linear: The Spotlighting effect is applied to an
area to which a DME nonlinear effect is applied.
Notes
•
The BZDM-9050 Texture Lighting Software (for
MVE-9000) is required to enable [Texture] or [Non
Linear].
An install key must be entered to use the software.

•
The Spotlighting [Non Linear] setting is effective
for the following nonlinear effects. For any other
nonlinear effect, the result of selecting the [Non
Linear] setting is the same as selecting [Flat].
