Houdini 19.5 Nodes VOP nodes

Conductor Fresnel VOP node

Outputs a physically correct reflection factor for conductive materials.

Since 14.5

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


Physical Parameters

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


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.



Incident ray direction.


Surface normal.
