let say that you make a normal map from a 3D model or an image
you then get a bluish picture saved as a PNG or other format for this normal color map!
now when you create a new file you add a plane and add to it this normal map and set some NOR value to get the 3D effect
butr how do you put back the color on it ?
do you have to do a UV mapping or can you do this with normal mapping and what settigns are required to get good results?
is this applicable to other type of normal map the other type than color coded bluish map ?
