Garry's Mod for PC is an open-source game distributed by Steam and is available online only. Being open source, Garry's mod is fully customizable and users are able to create and modify all aspects of the game, physics and all. Creating custom skins is something that many users of Garry's Mod enjoy doing, although some may not know how. Create your own skins for use in Garry's Mod with a image-editing program and the Photoshop VTF plug-in.
Extracting the Skins
Exit the Steam application and download GCFScape (see Resources). Open GCFScape.
Click "File," "Open." Select the directory of your Steam Apps folder, usually located under C:/Program Files/Steam.
Open up the source materials.gcf file and browse to "Group01," located in the HL2\materials\models\humans\male folders.
Right-click "Group01" to extract it to a place of your choosing. Your desktop is a common, easy-to-find location.
Creating the Initial Skin
Open the citizen_sheet.vtf file, located wherever you chose to extract the Group01 folder, with your image-editing program, such as Adobe Photoshop, GIMP or Google's Picasa 3. Click "Image," "Image Size."
Make the images resolution 2048 by 2048 pixels. Select the polygonal lasso tool.
Cut out both of the shirts. Click "Image," "Adjustments," "Desaturate." Create a new layer. Fill in the layer with any color of your choosing. Change the box that says "Normal" above Layer 1 to "Overlay." Cut out the pants the same way that you cut out the shirt. Edit their color and pattern any way you would like. Repeat for the undershirt.
Save the file as the same name and overwrite. Browse to
and copy and paste your Group01 folder into that directory.
