Odd Lighting on Animated object

I tried to import an animated box from blender and it results in very odd lighting as you can see in the picture I have bright and dark faces even though they are all supposed to be bright.
I already tried all combinations of normal import method and Normal Generation Method, some make it worse by making the object completely smooth. I also checked the normals in Blender and they all look fine.



Still desperate!
Anyone? :frowning:
