1. Create a sphere and a plane, and position the sphere over the plane. Create a light to illuminate both surfaces.
2. Create a specular material (a Phong or PhongE) and assign it to the sphere. The sphere is reflected in the plane.
3. Create a second material and assign it to the plane. The plane reflects the sphere.
4. Make each surface a different color so you can see the reflection of one in the other.
5. In the Raytracing Quality section of the Render Settings window, turn on Raytracing. This tells Maya to raytrace any surface whose Visible in Reflections/Refractions is toggled on. These attributes are on by default for all surfaces, but raytracing only works when you turn on Raytracing in the Render Settings window. To learn more about the Render Settings, see Render Settings window.
6. Perform a test render to visualize the results. If you want the sphere to reflect the plane, open the plane’s Attribute Editor and turn on Render Stats > Visible in Reflections. To test iterations of a scene, see Visualize interactively with IPR
