In architecture, light reflectance value (LRV), is a measure of visible and usable light that is reflected from a surface when illuminated by a light source. The measurement is most commonly used by design professionals, such as architectural color consultants, architects, environmental graphic designers and interior designers.

WebIf you use a Reflectivity mask in the Alpha Channel of the Normal Map (See section 6.5 below), slider values of 0.0 correspond to no reflections and 1.0 corresponds to whatever the grayscale value of the Reflectivity mask is. Slider values above 1.0 will multiply the Reflectivity mask value by 1x to x2 (the result is capped at 2.0). WebReflectance is defined by the amount of light reflected compared to the power of the light being transmitted down the fiber. Thus a 1% reflectance is -20 dB, which is about what you get from a flat polished air gap connection, and 1 part per million would be -60 dB, typical of an APC connector.
