That is a Kerkythea issue that was drive me crazy. Do you remember my thread: Does the normal map inverted in Wings3D?? I thought the problem was the Gimp's plugin, but then I realise that wasn't it when I mixed it with Substance Painter maps.
Because I started making the map to use with Kerkythea I was getting them weird in Wings3D and Blender.
I'm create this new post in Kerkythea to not polute your thread.
[edited]The thread I created was a mistake. I misunderstood how Wings3D works with bumps. (see that thread)
