I have two simple translucent circle sprites that I'm using as fake shadows (shown below) under some characters (not shown below). When the characters get close enough, sometimes their shadow circles can overlap - which is fine - but thanks to the default blending it doesn't look right. I want the shadow circles that do overlap to be visually merged/mixed so they maintain the same opacity, but instead they add together where they overlap like this:
I have to imagine there's some way to make this work with a shader, but I'm so bad at shaders that I can't seem to figure it out. Does anyone know how to solve this?
