How exactly do I edit a normal map like pic related? this is like looking at another dimension. Basically I made a few changes to my avatar's body mesh and now the normal map texture doesn't reflect the "weight" correctly in the places I made the changes. Even if I pop open the normal map in photoshop I have no real clue what sort of changes I have to make to it since this is all weird shit. Pls help me understand how all this blue/purple shit works and what do I do to make it apply weight to the texture where I need it to or if there's a program specifically to edit normal maps
