Remarks
This property represents the intensity value for light that slowly dissipates. Attenuation1 represents an attenuation constant as a fixed-point value with the valid values range from zero to MaxValue. Attenuation values are ignored for directional lights. For non-directional lights, avoid setting all three attenuation values to 0.0 simultaneously.
