areas in your scene. If you turn off this light, you don't have highlights and shadows to define your mod-
els' surfaces.
1 In the 3D panel, select Infinite Light 1 and note the changes to the information in the Properties panel.
With the light selected, you can see options to adjust the color of the light, the brightness or intensity,
and whether this light casts shadows. If the light does cast shadows, you can see options to indicate
how soft the edges of those shadows are.
2 Adjust the intensity down to approximately 50%. You will reduce this brightness since you will add
another light to the scene. Turn off shadows for this light, since you will use a Spot Light to create
shadows.
3 At the bottom of the 3D panel, select the Light button ( ) and add a New Spot Light to the scene.
4 The new spotlight appears. This is a light that emits rays in a conical shape in one direction. Use the
3D Axis tool to move the light around the scene. As you do, notice that the shadows cast by the ob-
jects change. If the light is no longer illuminating your objects, click the Point at origin ( ) button at
the bottom of the Properties panel to direct it back at the origin.
5 In the Properties panel, set the Shadow softness to approximately 50%.
Spot Lights emit light in a cone-shaped pattern in a specific direction.
At this point, you have two lights in your scene. The Infinite Light provides general illumination, while
the Spot Light, or your key light, provides the dramatic highlights and shadows for this image.
Materials
With your lighting set up, you can now make changes to the materials and see how they affect the result-
ing image. You will assign a gray metallic material to the Sphere object, a gold metallic material to the
Fleur-De-Lis, and a green plastic material to the Extruded Text object.
