(You may want to review the discussion of these
components in Chapter 7, ???Materials and Mapping.???)
In the Affect Surfaces section of the Advanced Effects rollout, you can toggle the check
boxes that will render only those components of the light on the surfaces they illuminate.
This is a good way to separate your renders into lighting components that you can later
control in compositing, although it leads to a longer workflow.
Figure 10.48 is rendered with the diffuse component of the lights in the scene.

Only the diffuse
component of the
lights are rendered.

Figure 10.49 shows only the specular highlights rendered.
Figure 10.50 shows only the ambient light rendered on the objects.
Ambient Light
Ambient light in 3ds Max is not a light per se; it is a global setting in the render environment.
Ambient light, in short, is an even light with no direction or source. It is a way to globally
brighten the entire scene to add an even light to all objects. Using too much ambient light
will wash out your objects and give you flat renders.
