the tex files are the original game texture format. All the hd texture use png or dds (dds not available for reunion).
Yeah, but i don't need any other UI upscale, i need the one that comes with Reunion by default, but converted in PNG format since i need to modify it with some elements that are present in UI upscales into those default textures.
For example, i need to add upscaled timer texture that is present in upscaled UI, though i don't want to modify anything else than the timer, that's why i need to have the stock UI in PNG, otherwise it won't work correctly.
Edit: The thing is, when is just insert some parts of UI, it starts to look for other PNGs, it doesn't merge with the TEX files, so that makes battle UI appear as black boxes 'cause of the missing texture.
