Spotlighting Settings
You can set up to three light sources (lights 1 to 3).
When the global effect combiner function is enabled, the
settings of the lowest-numbered channel selected for the
combiner are enabled.
Image surface settings
The following adjustments can be made to the image
surface struck by the light.
• Adjusting the brightness of the whole image
• Selecting the image surface effect
• Test sphere function
• Adjusting the roughness of the image surface
• Coordinate axis on surface of image
Selecting the image surface effect
Flat: The image surface is unchanged, causing the selected
light source to appear as the effect.
Non Linear: Spotlighting effect is applied to an area to
which a DME nonlinear effect is applied.
Test sphere function
A test sphere is a translucent sphere virtually embedded in
the center of the input picture to provide an intuitive way
for you to check the position and direction of the spotlight.
When you change the position or direction of a light
source, the side of the sphere closest to the light source
grows brighter.
For details, see “Relation between test spheres and
parallel light rays” (page 269).
Coordinate axis on surface of image
This sets whether the coordinates of a test sphere on a
surface move in conjunction with a DME image.
Move: The test sphere moves together with the DME
image.
Fix: The test sphere does not move, even if the DME
image moves.
