Beautiful shaders! I have a request, if you don't mind making it. I'd like an effect that will cause an object to fade only on one side? When the player walks behind a pillar or something, I'd like it to go semitransparent. I could do this with a tween on opacity, but I think it would look better if the bottom of the pillar or tree or whatever stayed fully solid, while the top became translucent to show the player.
I'd want the Opacity at the sprite's y=0 to be 0, and the opacity at the sprite's Y= height to be 100. Ideally, I'd want to be able to smoothly tween the effect on and off.
Thanks for all your hard work!
