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. |
