Generate a normal map from an image.
Generate Normal Map
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.
Parameters
These properties control the core behaviours of the node.
Parameter Details Active
Enables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance.
Depth Scale
Control the scale of the depth in the normal map.
Invert Normal X
Invert the direction for the normals generated along the X axis.
Invert Normal Y
Invert the direction for the normals generated along the Y axis.
Invert Normal Z
Invert the direction for the normals generated along the Z axis.
Inputs
These properties control the core behaviours of the node.
