# outerConeAngle

The radial angle, in degrees, at which the illumination from a spotlight becomes zero.

```
var outerConeAngle: Float { get set }
```

## Discussion

This property measures the angle from the light axis (the direction in which the light points; the negative z-axis of its local coordinate space) to the edge of the region affected by the light. Between this value and that of the [`innerConeAngle`](/documentation/ModelIO/MDLPhysicallyPlausibleLight/innerConeAngle) property, the light’s intensity varies linearly.

The default value is 22.5 degrees, matching the default inner cone angle and thus creating a hard-edged spotlight. Set the outer cone angle greater than the inner cone angle to create a soft-edged spotlight.
