These are server side models that replace a dead players ragdoll (using "Beefs Chunks!" for SM, unreleased) for specific players. I've chopped a set of these models for each player model, and the textures are referencing the originals (no skins/materials needed)! The only texture that is required is the red in between the limbs.

Excellent! This looks great. Why have you not released this Source Mod?
Just trying to stay unique is all.... if not for that, I'd share it in a heart beat!
