Normal map node¶
The Normal map node generates a normal map from its input.

Inputs¶
The Normal map node accepts a single greyscale image as input, interpreted as a heightmap.
Outputs¶
The Normal map node outputs the generated normal map.
Parameters¶
The Normal map node has the following parameters:
the format of the normal map (default, OpenGL or DirectX). The format should always be set to “default” when connected to the Normal input of a Material node. The correct normal map format for the target game engine will be generated when the material is exported.
the size of the normal map
the strength of the normal map effect
the buffer parameter decides if the input must be stored in a buffer before generating the normal map. Using a buffer is faster but can create artifacts in the normal map, and disabling this option will generate more accurate normal maps. It is recommended to enable the buffer while editing a material and disable it before exporting.
Notes¶
This node outputs an image that has a fixed size.
When using 3D Signed distance functions, it is recommended to use the normal map generated by the
