3D model looks cloudy once imported, how do you fix the cloudy look?

So I’m having this odd issue where I’m importing a 3D model of a car but it looks really off. It seems to almost be deformed/cloudy. I tried importing other 3D models to see if I can replicate it and it happened to only affect a few others but majority seemed fine. I have no clue what would be causing this or how to fix it. Maybe I have to do something in Maya or 3Ds but nothing I have tried has worked.

The above images are with a bone and the image below is with all the meshes separated. The image below is the way the model is suppose to look.

it looks to me like a lightmap issue. maybe bad resolution or overlaps. that kinda thing isnt really my forte though so its just an idea.
