Problems with imported models

[nerth]

Hello guys i still do have some problems with my own models in Warcraft reforged before it showed too dark now its shiny as a new car its wierd and i doubt its because of warcraft engine when i riped models and then worked on them in mdlvis i must have forgot something i dont know. I think that i have made a mistake in 3ds max maybe something with shadows and lightning i would really appreaciate any help. Thanks
