Specular section of the ifmTransmittance material
 
Weight
The amount of specular weight. A value of 0 shows no specular reflection. A value of 1 shows only the specular reflections.
 
Mode
The specular reflection of the material. Select one of the following attribute values:
 
Constant: The specular reflection of the material is angle independent.
 
Curve: The specular reflection of the material is defined by a custom curve, defined by:
Fresnel: The specular reflection of the material is defined by the Fresnel term.
 
Fresnel (Advanced): Same behaviour as Fresnel.
 
Color
The specular color of the material.
 
Roughness
The appearance of the specular reflection. A value of 0 describes a plain, smooth and highly reflective surface; a value of 1 describes a rough and dull surface.
