Well, I finally finished my first render with Renderman/RIS. I made the model in ZBrush using a caricature from Jit Leong as reference ( www.caricature.com.sg )
RenderMan 21 Update:
Scene has been converted by Leif Pedersen for RenderMan 21 and Pixar Surface Shader.
Burley Normalized Subsurface model was used to create a more lifelike skin render, taking advantage of new optimizations for noise and realism available in RenderMan release 21.2.
Initial Subsurface Color and Mean Free Path Color settings were taken from the pxrSurface Subsurface documentation and then tweaked slightly to achieve a cartoony saturation of skin. These values are important to make sure light penetrates accurately in various wavelengths through the skin.
Consequently, tweaking the Mean Free Path Distance, which we've set at 3, becomes very important, so that the light scattering doesn't overwhelm the model and appear like wax.
New SSS weight maps were painted to drive the Gain Subsurface attribute and provide subsurface in accordance with skin fat. This promotes a more realistic scattering of light through the surface.
Some more saturation and red tints were added to the Color Map in order to simulate richer blood vessels under the skin, especially near the eye and mouth area.
Two specular lobes were used to simulate the various layers of fat in the skin. One much rougher than the other.
A little bit of fuzz was added to show some "peach fuzz" hair in the skin.
Lighting had to be remade for analytic area lights and I added some kickers to show off some backscatter in the ears and hair. I took the liberty of changing the lighting to a more traditional soft portrait lighting setup to show a natural skin render.
Finally, some minor hair tweaks were made to improve the silhouette.
