Computes a normal map from a grayscale image interpreted as a height map.

The node converts an input grayscale map to a tangent-space Normal map output. It has a few user options to set intensity and encoding.

It is a very useful node that is used often to convert height map inputs to normal maps for realtime-ready materials. There are alternatives to be found in Normal Sobel and Height To Normal World Units.

Parameters

Intensity Float

Modifies the intensity of height map. Sets how intense the input height map is interpreted for converting to normals. Depending on input maps, values above 100 have little more effect.

Normal format Boolean

Inverts the Y coordinates of the height map (OpenGL). Sets how the Green (Y) channel is encoded. Basically a “Flip Green/Y” switch.

Alpha channel content Boolean

Fill the normal map’s alpha channel with the input texture. Fill Alpha With Input/Force Alpha To 1: This allows for the Alpha channel to be set to solid, instead of using the Input as an additional Alpha.
