Rough Glass представляет собой шероховатую поверхность диэлектрика. Подходит для матового стекла.
Опции
IOR
Определяет индекс преломления материала и влияет на общий вид, поэтому нужно подобрать IOR в соответствии с требуемым материалом.
Reflection color
Цвет отражения.
Transmission color
This is the color that light will be filtered to after being transmitted. Для идеально чистого стекла нужно установить Reflection и Transmission цвета на 1.0. The color given here will be applied to the material uniformly, you may wish to derive the color from the objects volume instead. (or use the glass2 material, which uses the volume for nearly everything).
Дисперсия
Enables chromatic dispersion to be calculated from the Cauchy B value (see below). Setting this to true will enable chromatic dispersion, aka splitting the spectrum into a rainbow of colors. Be warned this is an intensive effect that will greatly increase the number of samples (and photons, if applicable) that are needed!
Cauchy B
This is the B value to Cauchy's equation. (The value specified under IOR will be used for n)
Roughness
This determines how clear the material is by varying the roughness of microfacets. If your exporter uses the exponent to control roughness, higher values are more transparent, with 0 being a matte glass surface. If your exporter uses the direct roughness control, lower values are clearer, with 0 being a perfectly reflective and transmissive surface like the glass and glass2 materials, and .8 being matte. Values between .8 and 1 are an unrealistic "super-matte" and should be avoided.
