I am trying to make the PBR maps from the image. Then is this a proper setup? How should I connect the nodes to get PBR maps? I can write the script for batch PBR map creation, but I need to get the set up in material maker done.
The node setup depends on the input image. The normal map node expects a height map as input. In your case inverting the image works because stone is higher and darker than lava. But say you have an image of a wall with white bricks and dark mortar, and this won't work.
