open item editor
look for the item
right click the item and select item edit (parent)
once the window is open you will see the fields Wear (fight), Wear (Fencing), etc...
those are the cps
just open the skinobject.rcc and exctract the needed cps files
then once you have the cps files you need to view them with a hex viewer/ editor
there you can see the associated X file for that cps
once you have the X file, you need to view it again using the hex viewer/ editor
once you have opened the X file search for ".dds" thats where you can find the texture of the item
in conclusion you need .cps, .X, and .dds for the item... i hope this is the answer of your question and not unpacking the game.exe
