I'm into mathacking on servers, it's undetected, easy, and not that obvious. The problem is I want to code them for GMOD. I know how to use the VMT and VTF files, but there are other files I have no idea about. These files are VTX, PHY, MDL, VVD, and, SW. I have no idea what these file types are. Is it possible to code mathacks for these files. I want to create mathacks for the civilians on GMOD/HL2, please help.

Also I'm fairly comfortable with the VMT and VTF so is there a way to create mathacks for the civilians using VMT and VTF? I want to create mathacks from head to toe.
