In this paper and video tutorial, you will learn everything you have to know to be able to adjust and customize the Iray shaders used by the skins of your figures. At the end of it, you should be able to modify the exact properties which need to be modified, knowing exactly what you do, so that the final look of your rendered figures gets as close as possible to the one you have in your mind.
The paper documentation reviews the key Iray Uber properties necessary for skin shading, respecting the Iray Uber shader groups order, and explains the contribution of these various properties on the final skin look.
The video documentation is organized a bit differently, and is divided in three parts :
- an introduction to PBR shaders and how Iray Uber Base groups of properties correspond to the physical interaction of light with skin
- A second part detailing all the parameters influencing the final skin tone, with a strong focus on transmission and scattering (SSS) effects
- A third part detailing all the many possible ways to modify the glossy look of your figures, explaining how you can act on the properties of Dual Lobe, Glossy, Metallic Flakes and Top Coat to adjust this glossy look.
A pdf summary of the Video files is included so that you can find the information you want easily.
