I'm working on turning a cavity node setup I found online into a node group I can append to my blender files.
The setup uses several mapping nodes (that I already converted to math nodes so the values can be controlled from outside the group), but now I need image textures that receive the modified UV coordinates for the normal map (the "NormalTest.png" nodes in the image below).
The problem is that I want to control the image source from outside the node group and I don't know how to do that. Is there a node that can receive an image as a color input and output an image with the mapping applied? Or is there a way to control the image source from outside the node group?
