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.

 

In case anyone wants to see the actual object. It's not mine, I pulled it from a game.

 

I suspect the normals on those polygons are reversed. DS will cope with that, it always renders both sides of a polygon by default, but with the map also reversing the normal direction it's probably getting confused. Is this soemthing you made yourself or a third-party product?

These are objects I pulled from a game. I'm importing them into DAZstudio for later use. Each one is pulled with a texture map, specular map and normal map, but the normal map seems to cause odd issues.

With yellow in the map it suggests you have a map in 'World space' instead of 'tangent'.

I don't know if that's the cause of your problem but there are quite a few programs that can convert Normal maps to 'Tangent space' format. Its more common.

xNormal for example.
