Programs used:
- GIMP 2
- PakScape
1. Finding default skins
Open up pak3.pk3 found in Call Of Duty/main

Find a file called: "m1carbine.dds"
Make a new folder in Call of Duty directory, named something like: "my skin mod", copy the m1carbine.dds into your new folder.
2. Editing .dds files
Open m1carbine.dds in gimp(note: you need to install dds-plugin before this)
When you open the file, a popup appears. Just toggle Load Mipmaps off, since we don't need them.

For the simplest editing/result, we're going to deesaturate and darken the skin so it looks "cool".
Click Colors > Desaturate and choose "Average" then click OK.

Then change brightness and contrast in Colors > Brightness-Contrast

And we're done with editing! Save the image.
3. PAKing and testing
Now you should have an edited m1carbine.dds in your "my skin mod" folder.
Open up PakScape, make a new file and add a new folder, name it "skins"

Copy the m1carbine.dds into the skins folder. Save the file as .pk3 into "my skin mod" folder.

Launch CoDMP.exe, select mods, then your mod folder name, click launch and start a new server.
Done!
