Normal map editing as ordinary image After baking from the photogammetry mesh I've got the normal map wich has areas that need to be corrected. Can I edit the normal map in Photoshop as the ordinary image - apply patching, bluring, clone stamp and other similar tools?
I'm worring about the fact that the normal map encodes the normalized vectors and after editing these vectors will became denormalized and any artifacts can be appeared...
You can edit the normal map as much as you want, just use the good spectrum of colors, so use the eyedropper. If you blur the image then the 3D relief will be softer, if you put other colors than the normal spectrum you'll have dark spots:
