I was able to use nifconverter on the nif file in the skin folder but in the main directory, nif converter would give me an error when trying to convert that.
Don't try converting style's skopes it's already converted.
That might caused the problem on the hulk6 as well?
Nope, still dark. I never convert meshes unless they are dark first.
That might be a problem with your video settings?
Video settings are the same for all the other meshes/skins that work perfectly. Does the mesh work for you without being dark?
