update : ok so it doesnt really turns black but it makes the color more dark

 

Maybe it's mapped to a different material for some reason.

Try checking if it has instanceDiffuse enabled.

 

what is that ?

 

It's usually applied to the 2nd stage, makes that part of the material colorable

 

i have no idea what you are talking about... does it have something to do with blender ?

and btw, everything is somehow mapped to other materials, but everything looks fine except the body...
