I’m trying to experiment to see if it’s even possible for a game idea (crime solving sort of thing), trying to replicate a substance called Luminol. This is a chemical that basically reacts with oxygen in blood stains, and glows. So far so good, I’ve got that and that’s in this video:
But the chemical fades over time, that’s where the problem comes in. I’m not sure exactly how to do that, due to the way Unreal seems to handle Render to Target real time drawing. Below are pictures of my materials/blueprints:
So does anyone have any idea how I could achieve a per stroke fade effect, almost similar to particle lifespans?
