Specularity measures the overall fraction of light reflected by an object. The specular exponent determines the apparent shininess of the object.

Details

The specular exponent defines how sharply the intensity of reflected light falls off away from the mirror‐reflection direction. Higher values lead to more sharply defined reflections, typical of shinier materials. Values above 10 produce definite "specular highlights".
