Hey guys! Like most of you I've been playing around with all our fancy new shaders r100 brought, and there's one effect I just can't get down right: heat distortion. You know the type, when you look above an open fire and everything's all blurry and wavy.
I guess the hardest part is that any sprite you apply this to will have to end up being basically invisible, while still able to distort the background... if that makes any sense. Maybe it isn't possible the way I'm thinking of, but if it is, I'd appreciate some help trying to nail it down.
