Linking and unlinking image and spotlight
The spotlight can move together with a DME image, or be
fixed in place.
Source: Place the light source in source space. The
spotlight is linked and moves when the image moves.
Target: Place the light source in target space. The
spotlight does not move, even when the image moves.
Selecting the illuminated area
You can select the area lit by the spotlight.
FRGD: The light strikes the image foreground.
BKGD: The light strikes the image background.
Both: The light strikes both the image foreground and
background.
Surface Flat settings
For the currently selected light source only, you can
forcibly make the image surface effect flat.
Lighting shape
Creates the spotlight shape.
• 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).
