Here you will learn the difference between diffuse and subsurface reflections. Starting with a real-world analysis of subsurface/diffuse objects, you will then learn how in CG you can use either single-scattering
or multi-scattering to get the look you need. This lesson will also explore the Transmission Color options on transparent shaders to achieve a colored glass effect.
