Reflect

Overview

 

This node reflects a base image against a perfectly reflective three-dimensional surface.  The surface is defined by a height map provided by one of the node's inputs.  You can think of this node as what you would see if a camera were pointing directly at an irregular mirror while a picture was behind the camera.

 

Reflect Environment and Full Light nodes provide alternative ways to produce reflections through the use of environment maps.

 

 

 

Inputs

 

 

Input

Description

Base

The base image that is to be reflected off an irregular surface.

Heightmap

The red channel of this input is used as a height map for constructing the three-dimensional reflective surface.

Property

Description

Elevation

Increasing this value moves the base image farther from the mirror in the z direction, increasing the effects of distortions.  Negative values move the image closer to the mirror, and eventually behind it, at which point the image will begin to disappear.

Height Factor

Scales all values of the input height map by a given factor to quickly change overall elevations.  Entering a negative value will reverse elevations.
