To use manipulators to control hotspot and falloff:
1 Select the spotlight.
TIP When you select multiple spotlights, all their manipulators are accessible.
2 On the default main toolbar, click to turn on Select And
Manipulate.
Now when you move the mouse over the hotspot or falloff circle, the
circle turns red to show you can adjust it by dragging. Also, a tooltip
displays the spotlight name, the parameter, and its value.
3 Drag the hotspot or falloff circle to adjust the value.
The hotspot and falloff constrain each other, as their spinner controls
do.
Spotlight manipulators are described at the end of this topic.
To set the shape of the light beam:
1 Choose either Rectangle or Circle.
The shape of the light's cone changes to reflect the shape you chose.
2 If you chose Circle, you are done. If you chose Rectangle, you can now
adjust the
aspect ratio on page 7914 of the rectangular light in the Aspect
field.
To change a rectangular light's aspect ratio:
1 Choose Rectangle, as described above.
2 Change the Aspect value to the aspect ratio that you want.
The Bitmap Fit button is another way to set the aspect ratio. It is mainly
used with projections.
