LightSpotExponent Property

The spot exponent varies from 0.0 to 128.0 and provides an exponential interface for controling the focus or concentration of a spotlight (like the OpenGL GL_SPOT_EXPONENT parameter). The spot exponent and hot spot parameters are linked; changing one will change the other. A hot spot setting of 0.0 corresponds to a spot exponent of 128. A hot spot setting of 1.0 corresponds to a spot exponent of 0.0.
