Maxwell Render for Maya: Plug-in Help 1/34 doc v.1.1 - iam

The Subsurface editor panel provides access to the values which define the behaviour of a Maxwell
Subsurface layer. Each BSDF layer can have specific SSS properties.
Coefficient: When this is set to 0 it has no affect. The value sets the virtual thickness of your
surface in mm. This parameter acts as a multiplier for the inverse color set in the transmittance
parameter. The inverse color of the transmittance parameter will be absorbed faster.
Scattering Color: Scattering color is the reflectance of inner particles causing subsurface
scattering. This means that the incoming light will be reflected/ scattered in this color. This value can
be mapped.
Asymmetry: Asymmetry defines the isotropy of scattering. Asym=0 (default) means that light rays
will be scattered equally in all directions. A negative value will let the light rays go through while a
positive value will send the rays back. Besides the volumetric subsurface scattering explained above,
Maxwell Render also has a Single-Sided mode which helps you simulate thin translucent materials
like paper, leaves, and lampshades. The remaining parameters in this drop-down only control Single-
Sided scattering.
Use Thickness: Switch on to set user thickness values or texture maps.
Thickness (mm): Set a value or texture map chosen by the user.
Thickness Range: These values define the minimum and maximum virtual thickness and are
only available when a thickness map is used.
Surfaces properties
Roughness Value: Controls the diffuseness of the material (0 is a perfect mirror)
Roughness Texture: Roughness allows you to add tiny imperfections and miniscule details on a
surface to make it reflect light in a more diffuse way.
Anisotropy: This parameter controls how directional the surface reflections should be.
Angle: Specifies the anisotropy angle; the main direction of the reflected light.
