I am making a playertype using a custom model, but the shading is broken. everything appears as if it has the "Glow" effect, and isnt affected by the darkness of the world, unless you change the "Shadow color"

In the model i added a skeleton and everything, so all that is fine, but my only problem is the shading.
thanks!
P.S. i used the default gun model, imported and exported through shaper... that might be my problem, but i'd like to know for sure.
