SS | Subsurface (Number) | Subsurface scattering (0.0 = pure diffuse to 1.0 = subsurface scattering)
SM | Subsurface Map (Bitmap) | The Bitmap used to alter the subsurface value of the material.
SC | Subsurface Scattering Color (Colour) | Subsurface scattering base color.
SV | Subsurface Scattering Value (Number) | Subsurface scattering multiplier value.
CM | Subsurface Scattering Map (Bitmap) | The Bitmap used to alter the subsurface scattering value of the material.
SR | Subsurface Scattering Radius (Number) | "Average distance that light scatters below the surface. Higher radius gives a softer appearance, as light bleeds into shadows and through the object.
RM | Subsurface Scattering Radius Map (Bitmap) | The Bitmap used to alter the subsurface scattering radius value of the material.
SP | Specular (Number) | The reflectivity at the incident vector.
PM | Specular Map (Bitmap) | The Bitmap used to alter the specular value of the material.
ST | Specular Tint (Number) | The reflectivity color at the incident vector.
TM | Specular Tint Map (Bitmap) | The Bitmap used to alter the specular tint value of the material.
