SFM lighting bug on custom imported model need help

[Anleus]

Hello, been thinking about posting this in the technical support board instead, but all the SFM geeks are in here instead I think :ok:

I've been ripping models from Skyrim with the nif extractor tool, and ported it into SFM with wallworm. Everything worked great, until I got this annoying lighting problem.
Basically, when i put a spotlight to shine onto the model, the skin parts of the model doesn't seem to behave right. It turns black at the parts where it's supposed to have light, and weirdly enough works however when the spotlight is turned to face the front of the model.
I really wonder why the feck it turns dark when light is pointed behind the model, almost like as if the lighting details are reversed. Anyone have experience with light on textures and stuff like that on SFM? Or have had the similar problem? Didn't know jack shite on what to search on google to find a resolve to this.


Great
