Transparency
Here you can dene the transparency. If the material has a color, the color is automatically reduced
with increasing transparency. The equation is: color percentage + transparency percentage = 100% .
So a white material with 0% transparency is white (100%). A white material with 50% transparency
is 50% white (gray). A white material with 100% transparency has no color.
Refraction
You can simulate the refractive index by setting the Refraction value. Objects that are not closed, such
as a hemisphere without a cap, can give unexpected results with refraction. See Figures 1 to 3. In the
gures, the Refraction value is represented by the character ‘n’.
