A Target spot and a
Target direct
To create a Free spotlight, choose Free spot in the Create panel, click in a viewport, and
drag to set its initial direction and length. The one other difference between a Free spotlight
and a Target spotlight is that whereas the length of the Target spotlight is controlled
by its target, a Free spot has a parameter in the General Parameters rollout of the Modify
panel, as shown here. You set the length by adjusting this unmarked value next to the Targeted
check box.
You will study the General Parameters rollout later in this chapter.
Adjusting the length of a spotlight will not matter when the light is rendered; however,
seeing a longer light in the viewports can help you line up the light with objects in the scene.
Likewise, you can shorten the length of the light to clear some wireframe clutter from your
viewports.
Spotlights (including Target spots) are great for key lighting because they are very easy
to control and give a fantastic sense of direction.
Free Direct Light
The Free Direct light is identical to the Target Direct light, but it doesn??™t have the Target
node. Its parameters are the same as the Free spot??™s, and it is selected and moved in the
same way.
