Normal To Height HQ
In: Filters/Normal Map
A reverse-conversion node that attempts to convert a tangent-space Normalmap back into a Heightmap. This is the more advanced node; Normal to Height has less options and uses different calculations.
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. It can never replace a properly generated Heightmap!
- Normal Format: DirectX, OpenGL
Switches between different Normalmap formats (inverts the green channel).
- Relief Balance: 0.0 - 1.0
Blends between low and high frequency bias.
- Height Intensity: 0.0 - 1.0
Intensity or multiplier for the Heightmap, works a bit like global opacity.
- Height Normalize: False/True
Automatically scales the Heightmap range to use full contrast, like an auto-levels.
- Quality: Normal, High
Switches between speed or quality.
