This page provides information on the MtlSingleBRDF material node.

 

 

Overview


This node enables a BRDF material to be double-sided. It also enables materials to be transparent except in the case of specific ray types.

By default, all V-Ray BRDFs are connected to an automatically-generated MtlSingleBRDF in the VRScene before assignment to the Node plugin holding the geometry.

Node


The MtlSingleBRDF node contains the following input:

 

 

 

brdf – Specifies the BRDF material that will be affected.

 

Parameters


 

 

Mode – Specifies one of the following behaviors for the material:

Single-sided – The lighting on the "outer" side of the material will be computed. You can use this to achieve a fake translucent effect for thin objects like paper.
Double-sidedV-Ray will flip the normal for back-facing surfaces with this material.
Transparent For Camera Rays – The material will not be visible to camera rays.
Transparent Except For Shadow Rays – The material will be invisible to all rays except for shadow rays. This allows it to still cast shadows.
Transparent Except for Shadow/Refracted Rays – The material will be invisible to all rays except for shadow and refraction rays. This allows it to cast shadows and be seen in refractions.

Filter – Specifies a color filter to tint the material.

Allow Negative Colors – Enables the use of negative values in the color swatches of the connected BRDF.
