TranslucenceΒΆ

Using the Surface > Diffuse > Translucence Color attribute, the light is scattered through the surface. It can be used to make leaves or paper sheets translucent. Unlike SSS, this doesn't blur the illumination.

The Surface diffuse translucence set to black, white and green.

The Library/Materials/Surface2 shader for details. The User Guide/Shading/Sub Surface Scattering section.
