How can I reskin?

So, i’m trying to reskin a model. Here’s what I do, with GCFscape i grab a vtf file, with VTFEdit i change that vtf file into a TGA file, I open GIMP and change a few things, when I’ve finished, with VTFEdit I change the reskinned TGA file into a vtf file, then i put the file in the original directory and replace the old file with my new reskinned file. When I launch Garrysmod, the model is the same.

What am I doing wrong here!??!

The files have to be in garrysmod folder instead of original game folder.

C:\Program Files\Steam\steamapps\ben_ffxi\garrysmod\garrysmod

Put the new skin files into the equivalent folder to mine above. Click yes to replacing the existing files and you should be all set!
