Normal maps do not work in only the positive and negative x-directions.

Question

For some reason, normal maps do not work in only the positive and negative x-directions. Any idea why?

If I map the normal maps onto the albedo I can clearly see that they're getting passed into the shader correctly. alt text

But when I try to map them normally they work on all faces except on the positive and negative x-direction ones. No idea why. Any help will be useful.

I have this exact same problem and its very frustrating, i found if i adjust my mesh slightly so the surface normal is off the x axis its fine but i dont really want to do this. Did you come across a fix as i was going to ask a identical question?
