Spotlights are normal light entities, restricted to casting light in a basic cone shape. ArghRad adds new options for controlling spotlight appearance & behavior.

	_focus  scale	location: light entity    version: 1.00
	scale: > 0	default: 0
	Scales how quickly the light fades from the center of the spot, outward. It can create soft-edged spotlights that smoothly fade out from the center to the edges. The higher the value, the smaller the spot will be (trial-and-error may be required to achieve the desired results) Note: This option works separately from the _cone setting. When using _focus, it's probably best to set _cone to its maximum value 180.

Qrad3 requires two entities to make a spotlight. The light entity, and an info_null entity to point the light at. ArghRad adds several alternate methods of aiming spotlights, which do not require an info_null. Choose any one of the methods that you prefer. All spotlights point straight in the positive x direction by default.

	_spotangle  yaw pitch _mangle  yaw pitch	location: light entity    version: 1.00
	yaw: 0-360     pitch: -90-90	default: 0 0
	Aims the spotlight by yaw and pitch angles. Yaw goes from 0-360 degrees around the z-axis, like the angle key. Pitch goes from -90 straight down, through 0 horizontal, to 90 straight up.

	_spotpoint  x y z	location: light entity    version: 1.00
	x y z: any coordinate	default: none
	Aims the spotlight at the specified global x,y,z coordinate. It is similar to aiming at an info_null, without needing the info_null entity.

	_spotvector  x y z	location: light entity    version: 1.00
	x y z: any direction	default: 1 0 0
	Aims the spotlight by direction vector. This is the direction defined by a ray pointing from the origin (0,0,0) to the specified x,y,z value.
