Subsurface Scatter (New for v7.8)
The Subsurface Scatter section can be used to adjust the light transmission effect through the entire object.
Basic Settings
- SSS Falloff: This color determines the final color shown on the shadow area after the light passes through the object.
SSS Falloff = #FFFFFF (Default White)
SSS Falloff = #00AAFF (Sea Blue)
- SSS Radius: The approximate distance up to which light can scatter below the surface. Higher values will smooth the appearance of the subsurface scattering, while lower values will result in a more opaque look.
SSS Radius = 1.000
SSS Radius = 13.000
Advanced Settings
- R, G, B, A Channel Scatter Scale: These sliders change the strength of SSS effects that are defined by the RGBA Area Mask texture.
R Channel Scatter Scale = 1.000
G Channel Scatter Scale = 1.000
R Channel Scatter Scale = 1.000
G Channel Scatter Scale = 0.000
- SSS Distribution: This setting determines the gathering level of the light passing through the object's medium. A higher value gathers more of the scattered light.
SSS Distribution = 0.930 (Default)
SSS Distribution = 0.990
- SSS IOR: It determines the falloff of incident light. Higher values means that light falls off faster. The effect is quite subtle and changes the distribution function only a little bit. By the examination of many different materials, values of (1.3 to 1.5) have been found to work well for most materials.
SSS IRO = 1.000
SSS IRO = 2.500
- SSS Transmission Decay Scale: This value determines the light decaying level within the object's medium.
SSS Transmission Decay Scale = 0.000
SSS Transmission Decay Scale = 0.070
