Generating curvature from normals?
polycounter lvl 10
I have an asset I bought from the UE marketplace but I'm not super happy with how the wear matches my scene and would like to do a retexture. I recall having a Photoshop script forever ago that generated curvature form my normal map but have lost that. Anybody know of the script, or can explain the process of taking the RGB channels and setting the blending modes?

There are other automated methods like NDO/Crazybump and you can do it manually in photoshop with channel blending but it's been so long since I've done it that I can't remember too much about it
Alternatively, if you use Blender here is a node setup

But the tool that @musashidan linked looks pretty cool, too.
