Spot Parameters (Lights Tab)
Light X
Light Y
Position the light source in space by moving the
light parallel to the image plane along the X and Y
axes. Adjust the Light X and Light Y values to
change the shape of the light.
Change the Light X and Light Y is analogous to
pivoting a theatrical spotlight to follow a performer
on stage.
Distance Positions the light source relative to the image
plane.
• Increase positive Distance values to bring the
light source closer to the viewer.
• Adjust negative Distance values to place the
light behind the object and move the light away
from the viewer.
If Distance is negative, the light is seen only if
the object is rotated or displaced so that all or
part of it is behind the light source. (The light
source always points in toward the object not out
at the viewer.)
Color Determines the color of the light.
Click the color chip to access the system color
picker, use the eyedropper to pick a color from the
screen or enter RGB values into numerical fields
and press Enter.
Intensity Controls the brightness of the light.
Parameter Description
Angle Sets the angle of the light. This is analogous to
focusing the light.
Decreasing values create a smaller, more focused
light.
Parameter Description
Angle=50
Angle=150
