In this lesson, you work with a scene we created for your use.
This file can be found in the GettingStarted directory that you set as your Maya project:
GettingStarted\Rendering\ShadeOrange.mb
This scene contains a sphere modeled to resemble an orange.
The scene’s perspective view also has two settings turned on—Shading > Smooth Shade All and Shading > Hardware Texturing (Hotkey: 6)—which let you see the shading changes you are about to make.
