Material Editor > Type button > Material/Map Browser > Choose SSS Fast Material (mi), SSS Fast Skin Material (mi), SSS Fast
Skin Material+Displace (mi), or SSS Physical Material (mi), and then click OK.
Note: The SSS materials appear in the Browser only if the mental ray renderer is the currently active renderer.
The subsurface scattering (SSS) materials are provided especially to model skin and other organic materials whose appearance depends on more than one layer of light scattering. Autodesk VIZ provides four of these materials. Each material is a top-level wrapper (a “phenomenon”) for shaders whose controls are documented in the Standard mental ray Shader Libraries document. Click a link to see the mental images documentation for the shader.
Tip: When you follow a link to the documentation for mental images library shaders, scroll up a bit in your browser. The links tend to go past the title of the section, and there might be introductory content above the link location. If the link goes to the beginning of a section, scroll down instead.
| Material Name | mi Library Shader Name |
|---|---|
| SSS Fast Material (mi) | misss_fast_simple_phen |
| SSS Fast Skin Material (mi) | misss_fast_skin_phen |
| SSS Fast Skin Material+Displace (mi) | misss_fast_skin_phen_d |
| SSS Physical Material (mi) | misss_physical |
Also see Subsurface Scattering Shaders and the topics that follow it for more general information. See Physically Correct Subsurface Scattering for background information and tips about the Physical material.
Note: The SSS Physical Material can also be used as a shader for the Surface and Photon components of a mental ray material.
The SSS Physical material includes light controls that correspond to the lights array in the parameters for the misss_physical shader.
Lights—When on, the material is illuminated only by those lights specified in the list. When Lights is turned off, all lights in the scene affect the material. Default=off.
The remaining light controls are available only when Lights is on.
List of lights—Displays the lights you have chosen to illuminate this material.
Add—Adds a light to the list. Click Add to turn it on, then click the light object in a viewport.
Replace—Replaces a light in the list. Highlight a light's name in the list, click Replace to turn it on, then click the replacement light object in a viewport.
Delete—Deletes a light from the list. Highlight a light's name in the list, then click Delete.
