highlights on Phong surfaces. Use the Blinn surface
material for surfaces with bump or displacement maps to reduce highlight
roping or flickering.

Cosine Power
Controls the size of shiny highlights
on the surface. The valid range is 2 to infinity. The slider range
is 2 (broad highlight, not very shiny surface) to 100 (small highlight,
very shiny surface), though you can type in a higher value. The
default value is 20.
