You shouldn't test a skin like this, this takes too much time and ruins Your game files.
Firstly, Download this:
https://workupload.com/file/6nnVnaFMdjTDownload the .rar file and put the folder inside it in
C:\Program Files (x86)\MTA San Andreas 1.6\server\mods\deathmatch\resourcesGo inside the folder, delete the .dff file and replace it with the current id You are working with, so for example I want to work with id 101, I would delete the current "sale.dff", put 101's .dff file in there and rename it to sale so it replaces the old "sale.dff"
after You finish the png of the skin, Open the .txd file and put it in there with the skin's original name otherwise the texture will not show up and it will be a white skin. For example I want to test 101 ingame, I'd have to open the .txd file and put 101's texture PNG in there with its original name "WMYST"
This is really important, the name has to be exactly what it was in the game files otherwise it will be a full white skin with no texture at all.If You have any questions about this, mention me or PM me. Hope this helped
