Setting the Type of Light Source
When working with 3D model and Z space composite container, the type of light source you
select will determine the kind of lighting effect that will be produced. Depending on the type
of light source you select, different options are available. You can set the intensity, apply a
mix or set the softness of the edge of the light.
Setting the Light Source for a 3D Model Container
There are three types of light sources:
• Point: Combines both focused (specular) and diffuse light. You can use this Light Type
to create the appearance of a shiny surface lit by a point light source.
• Spot: Simulates the look of a traditional theatrical spotlight. Spot creates a small spot of
intense light whose falloff can vary.
• Distant: Creates a non-directional infinitely distant diffuse light similar to sunlight.
To set the Point or Distant type:
1. From the Type menu, select Point or Distant.
2. Set the following:

Parameter Description
Light X and Light
Y
Positions the light source in space by moving the light parallel to the
image plane along the X and Y axes.
Distance Positions the light source relative to the image plane.
Negative Distance values place the light behind the container and
move the light away from the viewer. Positive Distance values bring
the light source closer to the viewer.
Color Determines the color of the light.
Intensity Controls the brightness of the light.
