Refract Environment (Pro/Studio)

Top  Previous  Next

 

 

 

Overview

 

Refracts an environment map through a 3D surface defined by a height map.  This is equivalent to observing the environment through a transparent medium, such as water.

Inputs

 

 

Input

Description

Heightmap

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

Environment

An environment to be refracted through the surface. This input must be in latitude/longitude format.  The Make Environment node will produce environment maps in this format.

 

 

 

Properties

 

 

Property

Description

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.

Index

Specifies the refractive index of the surface.  The refractive index describes the degree to which a surface will bend light rays passing through it.

Skip for Color Only

During color-only renders, certain parts of a texture, usually those adding highlights or shadows, are skipped so that a flat-looking version is created.  Activating this property will cause this node to render as if it had a Height Factor of zero during color-only renders, thus flattening away any highlights.  This property doesn't have an effect during normal renders.  More information on color-only rendering can be found in the Using Effect Maps tutorial.
