3. Check one of the three numbered Shadow options to enable a shadow.
4. Select the tab next to the option to adjust the following parameters for that shadow:
• Shadow Bias: Lets you to correct render errors which may be created by extreme
positioning of the light sources. If you notice shadows in areas that should not be
shadowed or other render errors, try increasing Shadow Bias.
• Softness: Lets you softens the edges of the shadows, emulating the appearance of
shadows cast by a diffuse light source. Increasing the value to soften edges.
• Map Resolution: Lets you adjust the quality of the shadows. Higher values produce
higher quality, but increase render and preview times proportionately.
Applying a Motion Blur to a 3D Container
In real life, an object that moves quickly appears blurred. Imagine a camera taking a picture
of the moving object. The object in the picture appears blurred because the object moved
during the short time that the camera's shutter was open. If the shutter was open for a shorter
time, the object would appear sharper. The blur is most pronounced when the container
moves quickly or rotates through space and is less pronounced when the container moves
slowly.
As the Motion Blur effect is a very processor-intensive feature, you might want to turn it off
while you work and then enable it just before rendering.

If you nest a 3D container inside another 3D container that uses the Z space or 3D model
renderer, motion blur does not apply. In this instance, the 3D container does not render any
of its objects independently and thus does not have the motion blur effect.
To apply a motion blur to a 3D container:
1. Select the 3D container on the timeline.
2. In the Controls window, select the Motion Blur tab.
3. Set the appropriate parameters until you are satisfied with the result.
For parameter descriptions, see “Motion Blur Tab (Containers)” on page 291.
