?—? Glossiness. Often confused with specularity, glossiness determines how shine
spreads on a surface. A surface with high glossiness exhibits tight highlights or
???hot spots???; this option is dimmed if specularity is 0.
?—? Reflection. If you want a surface to reflect light, you specify how much with this
control; a mirror would have a high reflection setting.When you want to control
what??™s reflected in a reflective surface, you??™ll use the Environment tab.
?—? Transparency. This controls the degree to which you can see through a surface.
?—? Refraction Index. This value controls the amount that light bends as it passes
through a transparent surface.Material with an index of 1 doesn??™t bend light at
all; the index for glass is about 1.5, and for water, about 1.3. This control is
dimmed on surfaces with zero transparency.
?—? Translucency. This value specifies the degree to which light can pass through a
surface from behind, as it might a thin leaf or piece of paper.
?—? Bump. This controls a function that makes surfaces look irregular. It gives an illusion
of surface bumpiness, but doesn??™t actually cause any elevation or depression
of the surface geometry.
