I'm new to Normal Maps. I understand the concept, but I am running into a problem with this particular map and am hoping someone can help me out or understand what is happening. If you look at the circular emblem on this map you can see that it is surrounded by a yellowish color. On the object this map accompanies the yellow portion around the emblem turns black when this map is applied. Without the map (only texture and specular map applied) everything looks fine, but when I apply this normal map that area just turns black. Is there something particularly special about the yellow color on the map? Is there something I can do to fix the issue? Thanks for any help.
