Hello, I am creating a game where the player will use a lantern as a light source and wanted to create an effect where the film grain intensity increases in the areas that the lantern light touches or in lit up areas in general. But after experimenting with different values currently it will either not increase at all or increase areas I don’t want it to as well. Does anyone have any ideas or has experimented with something similar in the past. I would really appreciate some help!
