Diffuse color color – The color of the material. Note: The actual diffuse color of the surface also depends on the reflection and refraction colors.

Diffuse strength – A multiplier for the diffuse color.

SSS mix – Mix between the Diffuse component and the SSS component.

SSS mode  – Sets the Sub Surface Scattering Mode.

Diffuse bump tex – Allows you to select a texture for the bump or normal map for the diffuse component. The bump effect here is added to the General parameters bump effect. If no map is set in the General parameters or the map there is disabled, the map in this layer still produces its bump effect.

Note that if we add SSS mix value, GI and Lighting data, which use materials' diffuse component, go to VRaySSS2 render element. For example,  a value of 1 indicates 100% SSS component and 0% diffuse component.
