This is a specialized material that adds a conductive component to the geometry. It duplicates the features of Dali Physical.
R (Reflection)
A parameter that determines the color and intensity of reflection from the metal. An additional factor, the Fresnel coefficient for metals, will be used in any case.
Edge
This is a non-physical parameter that interpolates the reflection color between R and Edge depending on the Fresnel coefficient. Must be 0 to match physics.
Retro
Defines
- The share in the total reflection energy and
- Color with intensity
for Retro reflection.
IOR
Refractive index (real part). Can vary across the spectrum, in which case interesting spectral effects of color dispersion are possible.
K (Complex IOR)
The imaginary part of the refractive index. In practice, it enhances the brightness of the reflection.
Roughness type
Selects the model that will be used to calculate the Roughness of the material, if any.
GGX and Beckmann models are available.
Base
The value of the roughness of the material. 0 - smooth surface, 1 - completely rough. At high roughness values, there is some energy loss and darkening of the result.
Roughness can be varied across the spectrum by setting different values for different wavelengths. This opens up wide possibilities for shading.
Anisotropy
Roughness difference along the U and V axes. Can be changed along the spectrum by setting different values for different wavelengths.
Rotation
Rotation of the U and V axes. Can be changed across the spectrum by setting different values for different wavelengths.
Spectral range
Specifies the interval of the spectrum on which the spectral splines are defined.
