Spotlight cone displayed in a viewport
To adjust the beam angle and field angle, do one of the following:
■ Use the Hotspot/Beam and Falloff/Field spinners to increase or decrease
the size of the beam angle and field angle regions. For spotlights, these
angles are expressed in degrees.
■ Use manipulators to adjust beam angle and field angle by dragging in a
viewport, as described in the procedure that follows.
By default, the field angle is always constrained to be at least two degrees or
two units greater than the beam angle. The size of this constraint is a preference
that you can change in the
Rendering panel on page 7768 of the Preferences
dialog. The falloff value can range from 0 to 10,000 units.
When the beam angle and field angle values are close in value, the light casts
a hard-edged beam.
To use manipulators to control beam angle and field angle:
1 Select the spotlight.
