Strange problem with normal map

[1096bimu]

So I got this custom weapon mesh, I could import and see it in game and everything, except my normal maps don't work properly.

 

The most annoying part is that it partially works, so it's not like I got the wrong path name or anything. Basically everything with the normal map works except making bump on my model.

So alpha channel works which controls highlight levels, same as other textures I have edited, so I know it sees the texture and I got the right channel.

If I draw random stuff on the normal map, it also works, you see weird changes on the model's face normals in-game

But, if I apply the Nvidia normal map filter and make it blue like all other normal maps, there is zero effect on the model, alpha still works, but there is zero difference in how it reacts to light, flat faces are perfectly flat.

I have modified a lot of normal maps for other models in game, I know how it works. It's just not making any difference.

 

Screenshot:

This is with a normal map converted from all kind of black and white super high contrast random lines that I have drawn, but as you can see there is zero effect. however I know the map is there because the model is mated by my alpha channel.

Is the texture named Name_n.dds? Meaning Exactly the same as the difuse, but a _n behind it?

Is the pathing correct inside Nifskope?

 

Uh.. That's about all I can thin could be the issue.

I'm wondering if somehow you've reversed the normals. What program are you using? Can you load it back in flip the surface normals and reexport like in Max?

 

Actually if thats it upload the model and send me a link and I'll check in Max.

I flipped the normals in nifskope but still absolutely no sign of normal map. but I'll let you take a look at it, just email me and I will mail you the model. my email is just my username @gmail.com

 

It could not be path or naming problems because I can see the difference, and very obvious differences when I edit the texture. It just doesn't work properly.
