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
