Adding Shadows
Don't be too quick to create an abundance of light in your scene—eager to show off your

some interpretation to the audience.
A careful balance of light and dark is important for a composition. As Figure 10.24
shows, the realism of a scene is greatly increased with
the simple addition of well-placed shadows. Don't be
afraid of the dark. Use it liberally, but in balance.

Creating Shadows in Maya
Maya lights don't cast shadows by default; you need to

two ways, depending on how the scene is rendered.
The more common method of the two is to create
shadows by using Depth Map shadows. When you
