This is probably in need of an update because they are possibly undocumented/unknown issues with this shader. Works in the demo; I import and apply the shader in my project and the artifacts are really bad and it doesn't function properly; I import my sprites into the demo and the issues are the same, however, the shader functions when the sprites are resized very small, but only in the demo. My dissolve map is the same size as the sprite, so no issues there, and everything is perfect, it simply fails.
