What causes a mesh/skin to be dark in the game?

[SingleMalt]

I am still having trouble with Hulk6 from Style's skopes. The mesh is very dark in the game but not in the character select. I have used EZNifConvert to convert it but it is still dark. In fact all but one of the Style's skopes are dark. How are they for you guys?

when you converted the mesh did you run it through stumpy's lighting converter?

[SingleMalt]

Yes

Then I'd say the only way to fix it is to manually fix the lighting values in nifskope. I don't know why they're dark though
