5. In this problem, you will be adding lights to a model and controlling the light
properties to create a pleasing scene. Model the courtyard shown. The overall
dimensions are 15′ × 16′ × 4′ (wall height). Use your own dimensions for every-
thing else. Add lights as follows.
A. Turn on the sun and turn off the default lighting. Set the time to late in the day
so that the sun is close to the horizon.
B. In the
Sky Properties
category of the
Sun Properties
palette, select
Sky
Background and Illumination
for the
Status
property.
C. Add a point light at the center of each sphere.
D. Attach a glass material to the spheres that will make them look like they are
glowing. There are materials in the
Glass
category of the Autodesk Library
that can be used as a base for creating a new material.
E. Create a fill light above to illuminate the scene. This can be a point light or
spotlight.
F. Render the scene using the low preset to see the lighting effects.
G. Adjust the sun properties to create the look that you want.
H. Adjust the properties of the point lights and any other lights in the scene.
You may have to increase the intensity of the lights to properly illuminate the
scene.
I. When the scene is illuminated the way you want it, render the scene using the
medium or high preset.
J. Save the drawing as P17-5.
