Generating curvature from normals?

zombie420

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?

I haven't tried this but it looks like it's just what you need

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

I posted a Photoshop action that does that in this thread:

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