I decided to share my own reshade preset . The way I did this was I mimicked a film filter to give rdr2 some sort of moodiness and drama to it . I did not touch the color and its saturation since for me it’s perfect the way it is.
Instructions are on the readme file . Feel free to comment about what you feel , even if it is negative or positive because I want to learn more from you and the modding community 🙂 Cheers!
