Reflectance
Use this option to enable or disable the material’s reflectance.
Use this setting to define the reflective strength.
This setting is used to adjust the sharpness of the reflection (or of the matte effect). If set to 0%, the material will reflect like a mirror. Higher values will make the effect correspondingly more matte.
This setting can be used to darken reflections in regions affected by Noise. The visual effect is the same as a more-or-less polished surface with small outbreaks.
This effect is only noticeable with minor roughness, i.e., relatively sharp reflections. Small values will disable the respective effect, larger values will strengthen the effect correspondingly.
