Hi clockworkocean, thanks for your soon response. Your answer helps me a lot. I have 3 button of different color grading settings and how do I change the color grading when different button is pressed. Also I have a question. I am using the above method and i made only color grading settings enabled and rest of the pins are disabled. For example I have disabled the vignette intensity. The default post process settings for vignette intensity is 0.4. when I do the above method with vignette intensity disabled, will vignette intensity be used as default 0.4 even if it’s pins are disabled . please correct me if I am wrong with question. Thanks clockworkocean.
