Strange normal direction problem

[1096bimu]

I'm having a really strange problem with my mod here:

Specifically it's only the one named "caliburn" and its sheath that have the problem, the other ones are fine.

The problem is with how it reacts to light, I think my normals are facing the wrong direction but not just flipped. It's kind of complicated, you can see it for yourself in-game but screenshots won;t do it. So I made a simple diagram to explain this:

if you look here, situation A is what we want( all 4 lights are in the same position relative to the cube, and perpendicular to the edge between side 2 and 3).

Situation B is what happens when the normals are flipped.

 

however, my sword starts with B or D, I can't tell which. But when I flip it it just goes to situation C but not A.

If you look at the side labels in the middle, only sides 2 and 3 should be illuminated, side 1 and 4 should not because they are at an angle greater than 180 degrees to the light. If the normals are reversed then only sides 5 and 6 should be illuminated because they are opposite to 2 and 3.

What I have here is some screwed up normal that is not just flipped but also seem to have been rotated 90 degrees over some other axis, I just have no idea what's going on. I can't use the face normals command because it just screws up all my smoothing groups. I tried all the other ones and none of them work. Of course these models all look perfect in 3ds MAX, until you import and paste them into the game's nif file branches.

Would love some screens, and I do love your diagram aha :)
