How do i change a ui piece so that it works for other downloaded ui's? i downloaded a ui and everything on it works, but i wanted a few pieces like player and target windows from another specific ui i took the files for the pieces that i need out of it and ut them into my downloaded ui and they just mess everything up. how do i change it so it works for the ui? do i need to edit the file?
