Have you ever had trouble with getting proper transparency on line art? Perhaps some layers got messed up and need to fix the transparency. This shader will intake any black and white image and convert lighter colored pixels into transparency. What this does for line art is it keeps the line smoothing on the edges of a line by setting those values to their proper alpha. This makes it so the lineart can be properly overlaid over another layer. This package includes some basic code to save a sprite to your game directory, however it could be modified to solve a number of situations.
Feel free to use this for anything you like.
