I'm trying to replace the load screens with my custom ones through the use of loose files, however every time I load into the game they come out unrecognizable and fuzzy like someone broke my screen. I have been looking to see if they needed to be a certain image size, and even copied the already made loading screen size of 1024, 512. Nothing has worked. Do they have to be at a certain resolution or file size. They are all dds files.
