All nodes in the Specular group respond to specular light, which refers to specular light from direct (point- spot- infinite) sources only. The regular \u2018specular\u2019 node itself<\/a>, either separate or embedded in the PoserSurface definition directly is fast to calculate, but falls short for a neat illusion of about any real stuff except hard plastic.<\/p>\n This is why Poser offers alternatives, like Blinn<\/a>, or Anisotropic\u00a0<\/a>for microscopically grooved surfaces. In this series, Glossy can be considered as somewhat outdated, and available for compatibility reasons mainly. Glossy was introduced as an improvement over the classic Phong specularity, and added the suggestion that light sources have a physical size (while in Poser, they have not). So Glossy produces quite intense midsections in the round highlights; nice for point- and spotlights but incorrect for infinite lights unless these represent a sun.<\/p>\n Glossy makes sharp highlights with eventually a softening edge. In the image above the highlights are about equal size. The left pawn is regular specular, color white, value 1.0 and highlight size 0.05. The right pawn has the same color, the Ks<\/strong> value matches Specular Value and Roughness<\/strong> matches Highlight size, while Normals Forward<\/strong> matches the same option in PoserSurface.

\nThis leaves Sharpness<\/strong> as an extra parameter. It makes the width of the blur at the edges of the highlight. High values \u2013 up to 1.0 \u2013 produce sharp edges but frankly, values over 0.1 start to make quite an unnatural impression.<\/p>\n
