Bizarre shadow issues on ragdolls/player models.

Hi,

I’d like to voice an issue in regards to some bizarre graphical errors a friend has been experiencing during the process of posing ragdolls in Garry’s mod. The issues referred to are seen around the eyes and the nose of the ragdoll, in where there are strange splotches from shadows. A screenshot is provided.

A solution to the issue would be much obliged. Thanks in advance.
