Setting the shadow type and color

Shadow maps create soft-edged shadows. They are the default for all types of lights except Sunlight Systems. Ray-traced shadows render more slowly, but they make excellent shadow studies because their edges are so crisp.

To create ray-traced shadows:

  1. Select a light.

  2. Open the Modify menu.

  3. Open the Shadow Parameters menu.

  4. Turn on Object Shadows.

  5. In the Object Shadows drop-down menu, choose Ray Traced Shadows (Figure 5).

    Figure 5  Use the drop-down list to change the shadow type.

  6. Render the scene (Figure 6).

    Figure 6  Ray-traced shadows have hard edges.

You can set shadow color independently of illumination for both types of shadows.

To set shadow color:

  1. Select a light that casts shadows.

  2. Open the Modify menu.

  3. Open the Shadow Parameters menu.

  4. Click the Color swatch (Figure 7).

    Figure 7  You can achieve special effects by changing the shadow color.

  5. Choose a color in the Color Selector: Shadow Color dialog box.

  6. Render the scene.

  7. Repeat steps 5 and 6 until you are satisfied.


  • To mix the color of the light with the shadow color, check Light Affects Shadow Color in the Shadow Parameters rollout.

  • To project a map into a shadow, check Map and click the None button.
