Generate Normal MapGenerate a normal map from an image.
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 Amount||Changes the opacity of the new effect over the original image.|
|Depth Scale||Control the scale of the depth in the normal map.|
|Invert Normal X/Y/Z||Invert the direction for the normals generated along each axis.|
|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.||Envelope Modifier|
