Watch this video carefully (

https://reshade.me/) Then during setup, find the game executable but DO NOT run the game by itself. You will need the model importer XXMI (
https://github.com/SpectrumQT/XXMI-Launcher) so it works as a bridge between Wuthering Waves and Reshaders/Textures. Run XXMI everytime before running Wuthering Waves.
In order for Reshade to work, please follow the instructions in the Game notes above before just launching the game with reshade enabled by itself.
