Hair Shading/Texture pb?

Hi there, finally managed to import my first model into Skyrim, now there's something which I'm not sure what's causing it, most likely texture or shading. Below you can find a texture which shows the problem. Still to tiny issues left, hair place and scale, which I think is a bit to small.

Hope someone can give me some tips/help now.

Looks like the specular map is all-white, so the highlighting is at it's fullest everywhere. At least I assume that's what you're wanting to point out, as you didn't mention it.

In the alpha chanel of the normal map, you'll need to create some kind of texture there, check out some of the vanilla textures to get a feel for what it should look like. For the most part, with hair you can desaturate and run levels or somesuch from your diffuse texture and get a decent result.

Well it's fixed now, I had to add an alpha map to normal map as you said, thanks. Btw I guess it's not possible from Nik to rescale the hair, guess I need to redo everything no?

you can scale a mesh in nifskope, but it's limited and time taking if you want it to be exact, so probably faster to import it back to whatever kind of 3d modeling program you're using and scale it there.

I have moved verts in nifskope because i did not see clipping until textures were applied, also scaled a helmet to better fit the head.

Yea kinda like that that.

 

Redid the whole thing, scaled etc, now it's fine I'd say, but another problem showed up, which wasn't here before, could be a problem because of scale? (I doubt...)

 

Once I remove the NiAlphaProperty it's gone, so obviously a alpha problem, but thing is that the alpha is perfect on texture...so dunno :/ If it's matter I'm using the DDS presents from here http://skyrim.nexusmods.com/downloads/file.php?id=6152

Edit: Tried with DXT3, and more or less same result, here's a screen in NifSkope

Looks like issues with triangle sorting / alpha blend mode. This is more or less fixable in a 3d editor, but a major pain. Without going into much detail, the 'strips' of hair need to be combined in a back-to-front order, so the mesh renders properly.

 

However, in Skyrim, alpha blending on hair models won't render shadows, instead, use alpha testing only. Which also avoids the triangle sorting issue, and renders faster. (at the cost of losing the smoothly blended alpha)
