This is HQ Paintings for both Thief Gold & Thief II: The Metal Age games. They were created by hand using online galleries. To be unpacked/overwrited into game directory after everything else from ESRGAN Pack.
As you know, paintings in Thief game series were real paintings from the real world. So I found everyone of them and created more detailed textures for use ingame. Game textures were of various quality and sizes (256x256 and so on). I improved everything to 1024x1024. Every texture was edited to look more like Thief original ones in terms of crop, rotation, brightness, colors and so on. I consciously reduced saturation and colors and so on to match original textures. Few textures weren't found on internet and were filtered as much as possible with all available means. Enjoy.
This mod can be used with any mods and installations for this two games, not just with ESRGAN Packs. Just keep in mind that you need TFix patch to be installed for texture mods to work.
