Download Kaldaien's Untitled Project X on steam here : http://steamcommunity.com/app/359870/discussions/0/364041517007524857/ Extract the archive at the root of your Final Fantasy X/X2 HD Remaster directory. Then, grab my mod and extract to "\Steam\steamapps\common\FINAL FANTASY FFX&FFX-2 HD Remaster\UnX_Res\inject\textures"
Uninstall
Remove the dds from the inject folder (the name of each dds are inside the archive, so keep it)
