Figure 10.22 shows a Free Direct light.
Directional lights (including Target directs) are also great lights to use as key lights. You
can also use them for fill lights, although the hotspot size must be large to avoid seeing the
edges of the hotspot.
Directional lights are also used frequently to simulate sunlight, although their beams
must be quite wide to avoid any chance of seeing the hotspot or falloff area.

Omni Light
The Omni light in 3ds Max is a point light that emanates light from a single point in all
directions around it. Figure 10.23 shows an Omni light.

Unlike the spot and directional lights, the Omni light does not have a special rollout,
and its General Parameters rollout is much simpler, as shown in Figure 10.24.
An Omni light is shown rendered in Figure 10.25. Notice how the ground plane is
brighter directly below where the light sits.
Omni lights are not as good for simulating sunlight as directional lights are. The
Omni light??™s rays spread from a single point source, so by the time they reach their
subjects, the light direction and shadows will be too disparate across the scene.
