This fixes the Summer Shades for the Medic by reducing the clipping and changes the bone to use “prp_glasses” (which adds support of Medic taking off the shades during certain animations, like losing to RPS and the Neck Snap). It also adds $nocull to the material files, so the lenses no longer disappear from behind (this applies to all classes, however).

This fix was not done by me but was done by Zeugziumy! This is being uploaded on their behalf as he does not wish to fill out the Workshop's banking info.

This is also available to download as a mod (does not work on Casual Mode): Improved Summer Shades for Medic (Gamebanana Link)[gamebanana.com]

For Valve: If Extra class bodygroups is added as well, the Summer Shades should also include a "medic_glasses" "1" bodygroup setting to the Item schema, as it will look better without Medic's default glasses on top of it.
