You can enable shadows and set their properties and parameters to achieve the results that you want.

To enable shadows and set their properties:

1. On the Lights tab, under Parameters, select Shadows.

   

   Property	Description
   Type	Sets the type of shadow created. There are four types: Normal: The default shadow. Mid-Depth: Uses a mid-depth z-buffer to compute a shadow that usually yields fewer artifacts. Deep: Allows a transparent object to color light as it passes through. None: The light does not cast a shadow.
   Map Size	Select the map size. The default is 256 x 256.
   Offset	Experiment with self-shadowing effects. The default value is 1.00 and is intended to reduce self-shadowing artifacts.
   Opacity	Set the transparency of the shadows. By default shadows are opaque.
   Softness	Set the softness for the shadow.
   Color	Click the color pot to display the color picker, choose a color, and click Set—see Working with the Color Picker.
