Generate Normal Map

Generate Normal Map

Generate a normal map from an image.


Method #

This node generates a normal map based off the luminance values from an image, and comparing the relative change in value for each neighbouring pixel. Not 100% accurate, but great for quickly generating a normal map for a surface which doesn’t have one available already.


These properties control the core behaviours of the node.

Blend AmountChanges the opacity of the new effect over the original image.
Depth ScaleControl the scale of the depth in the normal map.
Invert Normal X/Y/ZInvert the direction for the normals generated along each axis.


NameDescriptionTypical Input
ActiveEnables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance.Envelope Modifier
