Importing hair alpha textures into Blender

[ruifly2]

I'm trying to modify some hair mods. I have successfullly imported the mesh from .nif file, color texture from .dds file and normal map from _n.dds file.

However, I could not figure out what the _hh.dds and _hl.dds do. I assumed they must be the alpha maps but they are different from blender default which is:

black reflects light and transparent absorbs light. Does anyone know a way of importing _hh.dds and _hl.dds into blender?

 

I'm currently using 2.49b version of blender. It will be hugely appreciated if someone can upload a sample .blend file with a hair model fully imported

 

Thanks a lot
