|---|
| Enable Spot Light: true | A cone with an emitting object inside. |
| Type | Defines the geometry of the inner object as described above. |
| Cone Angle | The angle from edge to edge of the spot light’s beam. |
| Cone Delta | Penumbra angle: the angle from the edge of the spot light’s beam over which the intensity of the spot light falls off linearly to zero. |
Light emitter
The emitter is generated from the following parameters:
