Node
Color – Specifies the color of the material.
Transparency – Specifies the transparency of the material.
Parameters
Subdivs – Controls the quality of glossy reflections. Lower values will render faster, but the result will be noisier. Higher values take longer, but they produce smoother results.
Cutoff – This is a threshold below which reflections/refractions will not be traced. V-Ray tries to estimate the contribution of reflections/refractions to the image, and if it is below this threshold, these effects are not computed. Do not set this to 0.0 as it may cause excessively long render times in some cases.
Theta Samples –
Importance Sampling – Enable to use importance sampling for the reflections.
Resolution – Resolution for the resampling of the BRDF used for importance sampling of reflections.
View Terms – Number of terms to decompose the view-dependent portion of the resampling matrix.
Half Terms – Number of terms to decompose the half-angle portion of the resampling matrix.
Back Side – When enabled back-side reflections will also be calculated.
