This video showcases this one specific effect for a few seconds. They move up and down the canyon object and the “layers” of color, for lack of a better word, seem to stay in the same place. It’s like a world-height-based mask. I’ve opened the UE5 project myself and those assets all share something that gives them those layers based on their world height, but I can’t exactly figure it out.
I want to imitate this in UE4 but it’s beyond my knowledge to know where to start. I’ll try digging into the UE5 project myself again, but any help is appreciated.
