Phong exponent

WebIn the specular workflow it uses colours to define intensity and the specular colour - but in game engines especially it's a waste of texture memory as most surfaces have a specular value of approx 0.5 so you generally don't bother. Some engines let you use a custom spec value or map though as an option for stuff like skin and gemstones but ... WebIn 1977 the Blinn-Phong shading model was introduced by James F.
