Conductor Fresnel VOP node

Outputs a physically correct reflection factor for conductive materials.

On this page

This operator supports two different ways of defining relevant material properties:

Parameters

Physical Parameters

When enabled, use physical parameters rather than intuitive color parameters.

Reflectivity

Controls the reflectivity of the surface when facing the camera.

Edge Tint

When the surface is seen from a grazing angle, the color transitions to this value. This tinting is typical of conductive materials.

Refractive Index

The refractive index of the conductive material.

Extinction Coefficient

The extinction coefficient of the conductive material.

Inputs

nI

Incident ray direction.

nN

Surface normal.
