The specular highlight color is the color of spots where the object reflects light very strongly. Hardness Also called shininess, hardness usually ranges from 0 to 255 and controls the size of specular highlights. Look around you at different surfaces and notice that the harder surfaces, such as metals, have small sharp highlights, while wood or paper has larger diffused highlights. More advanced software allows custom defined falloff of specular highlights to simulate a wide range of surface types. Reflect Reflect attribute determine how much of an object's color comes from a reflection of other objects.
True reflections require raytracing calculation and are extremely time consuming.
Some software allows the use of reflection maps that wrap an image around an object to simulate reflections. In such software, the reflect attribute determine how much of the reflection map colors are mixed with the color of the object. The bright attribute determines whether the object appears to be self-illuminated or glowing with its own light. This does not mean the object emits light that can illuminate other objects, it only means the object appears to be glowing. The bright attribute is useful for objects such as car headlights, building windows, and light bulbs.
