The rendered result (shown in Figure 7.72) looks a bit flat. Specular highlights help
make a 3D object look real, but highlights don??™t show up on flat surfaces.
For example, in Figure 7.73, you can see three cylinder objects of varying flatness. The
cylinder with the most rounded sides shows the highlight the most.
You can see a highlight on the black tire part of the wheel, but there??™s no highlight anywhere
on the white hubcap and only a little highlight on the red bolt. One solution is to add
more curves to your model to try to bring out the specular; another solution is to change
your material somehow. This decision can be made depending on how close you will see
the wheel in any of your shots. If the wheel is only seen from a distance, there is no need to

further detail the model. Because we will only be seeing the wheel from a distance, we will
alter the material. We can add a few things to bring out the shine in the material.
