Working with Lights
Light sources are points in three-dimensional space that emit light, causing objects (with
materials that can be affected by light) to appear illuminated. Light sources are modeled as
non-directional point sources that you can position in 3D space relative to the objects in the
scene. You can adjust and animate the direction, size, shape, color and intensity of a light,
and control the ambient light on the entire container.
To use lights effectively, place as few lights in a scene as necessary to avoid a bleached or
washed-out appearance. Also, use appropriate light settings for the material you use. For
example, if you use a concrete-looking material, do not make the material shiny or have a
bright specular color. Concrete is not usually shiny in real life.
Although you can add light to 3D model and Z space composite containers, you can only
add shadows to 2D composite containers. Different options are available depending on the
type of renderer the 3D container is using.
Adding Light to a 3D Model Container
You can add up to three light sources to the entire 3D model container.
To add light to a 3D model container:
1. Select the 3D model container on the timeline.
2. Select the Lights tab in the Controls window.
Sample # menu Sets the number of samples that are taken.
Higher values take longer to preview and render but provide smoother
blurring.
