Importing a skin?

[Strohd]

I was just wondering if im doing something wrong or if its something else. A few items on the workshop have skins available for download. So I downloaded one and put the corresponding materials and models folder bits in the right places. The item I chose the skin to replace now has 2 files of the molde, the original and the skin, however the skin does not appear. Any advise on what I did wrong?
