Hello,
I regularly add images to the colored studio logo Textures.xbt file. I use the Kodi Texture Tool. When I finish up and copy the modified file back to Its location in the add-on's resources folder, LibreELEC then refuses to read it at all. Of course I make sure there is only one studio entry in the Nfo file, otherwise it doesn't help at all. Anyway, LibreELEC (AFTER file mod) only displays the text from Nfo file Studio line. No image.
If I copy the EXACT same updated Textures.xbt file into Kodi on my Shield / Android TV or macOS installations, its flawless.
Any ideas?
