It works so thanks for this. I do however, like to try out other blood mods and so this is a general question but whats the best way to uninstall this mod. Installing I used package installer with OpenIV with the oiv file but whats the way to uninstall? Do I go through OpenIV, delete files manually from the game folder? I don't want to uninstall and reinstall the game fresh so whats the easiest way?
