This model is used a lot on ZM servers. It's the Charple model from hl2. The skin is horrible (it's a toasted guy), so I decided to make a new skin to replace the default one. It has GLOWING red eyes, so you can see them on dark areas. I also added a normal map with alpha, and I played with the VMT to get a realistic phong effect.
Remember, this uses a pre-existing model.
Enjoy!
