I don't know why I cant find this anywhere online, but I'm creating a character for my game and I want him to almost glow black because he's a shadow person. Of course I cant use bloom since that only works for colours with brightness, and I cant use a light because a black light just wouldn't do anything. so I'm very confused I don't see why this wouldn't be possible, I mean I'm not a unity developer but surely making something glow black isn't that hard. right?
Ive tried using a particle system, but it didn't give the results I wanted. Some particles cluster together and create an ugly effect and also having less opaque particles results in them overlapping and having patchy transparent and opaque spots. It also slows the game down a lot compared to a basic glow effect like I need. Of course if there's ways to circumvent this using a particle system I'm open to suggestions.
Here is an example of "black glow" https://2.bp.blogspot.com/-eMAczq5WtXo/VWb3afZBODI/AAAAAAAAA7c/GXAaFg8D48k/s1600/17.png
