So the case is that I’m very simple on programming in Blueprints so I’ve followed a tutorial on YouTube of a Post Process Echolocation filter. This one —> https://www.youtube.com/watch?v=YoQGYuR65qs That consists in making materials and putting them in the Character Blueprint in the Post Process Materials in Array and making a Blueprint Sound Generator for the Decal. My problem here is that I have in my Post Process Materials/Array 1 material for the white outlines and another to make the environment black like the first image. But when the Decal is being displayed It is not visible because my black surrounding material covers it completely and I do not know how to make the Decal show above the black material in order to have Outlines + Dark + Decal.
