This node defines a spotlight style light source.
A spotlight is placed at a fixed location in 3-space and illuminates in a cone along a particular direction. The intensity of the illumination drops off exponentially as a ray of light diverges from this direction toward the edges of the cone. The rate of drop-off and the angle of the cone are controlled by the Drop Off Rate and Cut Off Angle fields.

Determines whether the source is active or inactive. When inactive, the source does not illuminate at all.
Illumination intensity of light source. Valid values range from 0.0 (no illumination) to 1.0 (maximum illumination).
