{% tab title="Ouputs" %}
**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.
