Hi, I'm looking for outline/glow effect, which I can apply to 2D sprite. I don't care about 3D. Something pretty simple, because it has to be efficient on mobile devices. I know I can make second sprite with outline made in any graphical editor, but I have a lot of spritesheets, so I think shader will be better option. I only found somewhere extension or something, but it was said it doesn't work with sprites (3d crap only). I'm also aware that unity pro has that feature, but it's not worth...
