I want to add a similar distant blur seen in AC2, (screenshot below), which looks like it may be blurring just the colors and not the values of the image, or maybe it’s some sort of bloom/glow that doesn’t brighten but just has the blurring qualities. Maybe someone will know exactly what it is which would be helpful. Whatever it is I hope you get what I mean from the description and image.
It also becomes greater the further distance it is but I think I can do that myself, feel free include how to do that too if you want to though. I want to specifically do this in a post process material.
