Quote - These four are all Blinn at various settings. The Blinn node can accurately portray a very wide range of micro-bumpiness, from nearly smooth to craggy. (Microscopically craggy, of course. You could not see the little mountains with the naked eye.)

what if we wants a wide backlight specular and small specular infront.
then we combine one blinn and a normal specualr. right?
