Overhauled the materials and bodygroups, the whole model is much more customizable now. and added a skin to disable the rimlighting

The lenses are a little weird, if theyre ever pure white, just use mat_reloadallmaterials

Updated the names of most of the bones to fit SFMs naming system, makes the model look much cleaner as well as allowing Left and Right color coding

Added a bone for the glasses so you can move the whole glasses model

This might mess up your model from a session that had the previous version spawned in already.
You can try reattaching the model, but if that doesnt work youll probably need to spawn in a fresh one.
