Translucent Modifier

Create a translucent radiance modifier from a reflectance and transmittance.
The sum of the reflectances and transmittances must be less than 1 and any energy not transmitted or reflected is assumed to be absorbed. The resulting material will always be grey with equivalent red, green and blue channels.
name
Text to set the name for the modifier and to be incorporated into a unique modifier identifier.
diff_ref [Required]
A number between 0 and 1 for the diffuse reflectance of the material.
diff_trans [Required]
A number between 0 and 1 for the transmitted diffuse component. This is the fraction of transmitted light that is diffusely scattered.
spec_trans
A number between 0 and 1 for the transmitted specular component. This is the fraction of transmitted light that is not diffusely scattered but passes through like a beam. (Default: 0).
spec
A number between 0 and 1 for the fraction of specularity. Specularity fractions greater than 0.1 are not common in non-metallic materials. (Default: 0).
rough
Roughness is specified as the rms slope of surface facets. A value of 0 corresponds to a perfectly smooth surface, and a value of 1 would be a very rough surface. Roughness values greater than 0.2 are not very realistic. (Default: 0).
modifier
A translucent modifier that can be assigned to a Honeybee geometry or Modifier Sets.
