Normal to Height


Normal to Height

In: Filters/Normal Map

Intermediate

Description

A reverse-conversion node that attempts to convert a tangent-space Normalmap back into a Heightmap. This is the slightly simpler version; Normal to Height HQ has more options.

Useful for when you only have a Normalmap source, yet still want to perform operations combining it with a Heightmap. Keep in mind that this will never be able to provide a 100% correct result, as information is lost by nature of the process when Height is converted to Normal. If you tune the settings accordingly, this Non-HQ version does do a decent job of converting simple details.

Parameters

  • Relief Balance0.0 - 1.0
    Adjust the extent to which the different frequencies influence the final result. This is largely dependent on the input map and requires a fair bit of tweaking.
  • Normal FormatDirectX, OpenGL
    Switches between different Normalmap formats (inverts the green channel).
  • Global Opacity0.0 - 1.0
    Adjusts the global opacity of the effect.
