};
And for the backpack, i only remplaced the "txd" and "dff" of the original skin, in "mods" = "items"
For the Coyote, it's the "1252.dff" and "1252.txd", check it in the script files "core".
I didn't creat new backpack, i juste edit the backpack script in all of the scripts files, use "control - F" to search the info of your backpack, and edit it.
