Well you can't test it in the server even if you replace the .txd file with the shader you designed cause once you enter the server the files you that you have replaced will be re-loaded once again and the default shader will be replaced so the only way to test a modded skin is in a private server or in the map editor and for that you can check Liso's and Harb's post.
anyway you will find all the shader .txd in this folder Show content
