Mesh Has Black Faces and Recalculate Normals Outside (Ctrl+N) Change Nothing everyone.

I'm still "intermediate" in Blender.
I usually mod 3D model from TESIV:Oblivion game.
Know a bit about: importing, exporting, cutting mesh, UV mapping, bone weighting, etc.
But haven't learn to make 3D model from 0.

Usually, there's commmunity that likes to rip 3D model from games.
And so, I import .obj file to Blender 2.49b, but found this issue on the mesh:


Anybody know how to fix it?

(I follow this link: Why are some faces in my mesh darker? but nothing change)
Found solution!
Use NifSkope, right-click on the mesh, choose Mesh > Face Normals.
